The sentence giving the highest theoretically possible total score seems incorrect to me. It gives high scores for all 2s appearing, and for all 4s appearing, but the highest possible score will occur when 2s always appear except when a 4 must appear in a sole vacant spot in order to combine with another 4, then 8, then 16, etc. -- ScrabbleCurling ( talk) 01:54, 3 May 2014 (UTC)
I know we're supposed to use videos sparingly here, but I think that one would be beneficial to this page. It's one thing to say that the tiles move in a direction and combine if they're the same, it's another to see them go up to, say, the first 32 tile. Any thoughts? Anyone able to make one?

Given the large interest in making clones and AIs for this game, I have added a section more clearly specifying the rules. I haven't been able to find any exact descriptions of these other than the source code of the original game.

First of all, this line smells like original research. Secondly, it's wrong -- the game randomly spawns 2s or 4s. If it spawn all 4s, one would only need 512 such tiles. Also, what a "join" is is not obvious. — Preceding unsigned comment added by 24.7.84.130 ( talk) 08:29, 12 April 2014 (UTC)

Change "Therefore, the highest theoretically possible total score would be 1,835,012 if only 2s appear, and twice this value in the case of 4s only." to "Therefore, the highest theoretically possible total score would be 1,835,012 if only 2s appear, and HALF this value in the case of 4s only.", because as it is right now the sentence doesn't respect the formula shown above.
Thank you.

The highest total score section is still not correct; it says "Therefore, the highest theoretically possible total score would be 1,835,012 if only 2s appear, and half this value in the case of 4s only." As the table shows, if you get a 131072 tile (from only 4s appearing), you could get a score as high as 1966080. In fact, you could build up the earlier tiles using 2s to score even higher.
Besides, someone should add in the code that the player gains 4 points if the tile generator would choose that tile so the player is not cheated for any points. — Preceding unsigned comment added by 84.202.189.96 ( talk) 20:13, 2 July 2014 (UTC)
Thank you. Mpozar ( talk) 23:18, 9 May 2014 (UTC)
The highest score possible is 3,932,100 and could be achieved as follows:
Only 2s appear until the board is filled with the following tiles:
{65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 2, 2}
At this point, the 2 2s could be merged. If a 2 appears, the game is over - the board is full and no merges are possible. However if a 4 appears, the tiles would then be:
{65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 4, 4}
Merging could then continue, allow the user to get a 131072 tile. Assuming all subsequent new tiles were 2s, the user could end up filling the board with:
{131072, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 2, 2}
At this point again the 2 2s could be merged, but the next tile would have to be a 4 or the game would be over. If a 4 appears, the tiles would then be:
{131072, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 4, 4}
Merging could then continue, allowing the user to get up to a 65536 tile (with the 131072 tile remaining).
Gameplay could continue in this fashion, where each time the board gets full, 2 2s can be merged, and the next tile must be a 4 to prevent the game from ending. Ultimately the user would end up with:
{131072, 65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 4, 4}
After merging the 4s into an 8, either a 2 or a 4 would appear, and the game would end with the board:
{131072, 65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, (2 or 4)}
Total score from merges that created each tile:
Tile | Accumulated Score |
---|---|
131072 | 1966080 + 131072 - 4 |
65536 | 983040 - 4 |
32768 | 458752 - 4 |
16384 | 212992 - 4 |
8192 | 98304 - 4 |
4096 | 45056 - 4 |
2048 | 20480 - 4 |
1024 | 9216 - 4 |
512 | 4096 - 4 |
256 | 1792 - 4 |
128 | 768 - 4 |
64 | 320 - 4 |
32 | 128 - 4 |
16 | 48 - 4 |
8 | 16 - 4 |
Total: 3,932,100

The result of the move request was: no consensus. Both the original and modified proposals appear to deviate from the guideline naming convention for video games. While guidelines are always open to exceptions, no compelling argument for the exception appears in the discussion below. Xoloz ( talk) 16:15, 20 June 2014 (UTC)

Of course this is not a video game guide, but should there be a sentence or two on basic strategy, or links to high-quality further discussions of strategy?
Came here via the reassessment request in the talk page template. Leaving this as C-class, though even that's pushing it. Some ideas for improvement below:
The article repeatedly mentions that Gabriele Cirulli does not make money on the game, but this is no longer accurate.
His official iOS version of the 2048 game: > https://itunes.apple.com/us/app/2048-by-gabriele-cirulli/id868076805 now includes advertising, and users must pay $0.99 to remove the advertising.
His website does still allow people to play the game for free. Mkilby ( talk) 12:03, 30 March 2016 (UTC)

I'll make an initial review of this by the end of the week. Grabbing it now as it's a game I've spent plenty of time on. I see that the nominator hasn't made many edits to the article but it's not in a quickfail state. I do, however, see sourcing which will need serious improvement if this is to pass—as a couple of examples, student newspapers are not appropriate sources, nor are blogs, and nor is the primary source of DuckDuckGo. Conversely, once all the bad sources are stripped out, to ensure breadth and depth of coverage we'll want to make sure we're including as many reliable sources as exist. — Bilorv ( talk) 23:17, 15 July 2020 (UTC)
Referencing:
Clones written in C++ and Vala are available. There is also a version for the Linux terminal.has only primary sources. It needs either secondary sources, or removal if no secondary sources have discussed this code—otherwise there is no evidence of significance (I could write a version in Brainfuck but that wouldn't be information suitable for Wikipedia).
Content:
The game can only last a finite amount of moves, and the theoretical limit for the highest tile on a standard 4x4 board is 131,072.Says who? This isn't routine calculation.
This is perhaps more work than I expected from a first viewing and it may be too early to get this article to GA. In all honesty, I think the current article is C-class (or possibly Start-class) rather than B-class in quality. Let's see if we can get it up to B-class at least over the course of the review.
I'm leaving the article On hold and the review will be failed in seven days if there is not substantial progress in the referencing quality. If there's substantial progress then we can continue onwards with more low-level details. Even if the review fails, I'm interested in helping improve this article. — Bilorv ( talk) 15:53, 20 July 2020 (UTC)
Hi Dgpop, I saw that you're editing the page at the same time I am. I'm trying to get it to pass a GA this time around, and I'm following the suggestion left on the TP. I'm just following the suggestions left on the previous GA review (about six months ago). Are you also planning to do so? If so, then we could do a joint nomination or something if possible. One more thing — the picture being that large just don't work on a laptop, it's too big and the text does some funky things, so I'm undoing those, hope you don't mind.

Hello, I am planning on reviewing this article for GA Status, over the next couple of days. Thank you for nominating the article for
GA status. I hope I will learn some new information, and that my feedback is helpful.
If nominators or editors could refrain from updating the particular section that I am updating until it is complete, I would appreciate it to remove a edit conflict. Please address concerns in the section that has been completed above (If I've raised concerns up to references, feel free to comment on things like the lede.)
I generally provide an overview of things I read through the article on a first glance. Then do a thorough sweep of the article after the feedback is addressed. After this, I will present the pass/failure. I may use strikethrough tags when concerns are met. Even if something is obvious why my concern is met, please leave a message as courtesy.
Best of luck! you can also use the {{done}} tag to state when something is addressed. Lee Vilenski ( talk • contribs)
Please let me know after the review is done, if you were happy with the review! Obviously this is regarding the article's quality, however, I want to be happy and civil to all, so let me know if I have done a good job, regardless of the article's outcome.

It contains copyright infringements-
It has, or needs, cleanup banners that are unquestionably still valid. These include{{cleanup}}, {{POV}}, {{unreferenced}} or large numbers of {{citation needed}}, {{clarify}}, or similar tags. (See also {{QF-tags}}).-
It is not stable due to edit warring on the page.-

The site elgoog.im has a version of 2048. Should this be included? Mariobros12345 ( talk) 19:27, 29 May 2021 (UTC)
The "Strategy and AI" section that I added (see this
revision) was removed by Dgpop. I feel strongly that its content is important. The most remarkable part about the game that a casual player is not likely to know (or believe) is the achievability of larger tiles, including that with over 80% probability, one can achieve a 32768 tile. The strategic depth has both spawned a loose community of expert human players, and made the game of interest to AI researchers. And the featured article nomination was declined largely due to absence of discussion of scholarly works related to 2048 strategy and AI. However, I will let other editors re-add the section, perhaps partially or in a revised form.
16384 8192 4096 2048 128 256 512 1024 64 32 16 8 2 2 4 snake
A common strategy is to build a snake from the highest to the lowest tile. Despite its name, certain reorderings are fine: For each row in the figure, we can independently set whether the numbers increase to the left or to the right; and (for example) "32 16 8 64" also works.
After learning the snake strategy, many casual players routinely get 2048 (thus winning the game) and 4096, but struggle to get 8192. The requirement to move can shift big tiles, which is often hard to recover from. And out-of-order tiles (especially larger tiles and in the middle of the board) deprive the player of the needed space. However, despite the random element, planning ahead can be remarkably effective, with a number of expert players, and several strong AI.
Using current (as of 2022) AI, [3] the probability of making a 16384 tile is over 95% (and likely over 98%). The probability of making a 32768 tile is over 3/4, and under perfect play expected to be over 80%. The probability of making a 65536 is over 3%. After some near misses, in 2022, 65536 was finally achieved by a human. [4]
To reach 65536, the snake or PDF (described below) at the end would occupy every single square (unless one gets a 4 at the end). The optimal probability for 65536 is expected to be low due to the need for perfection just before 65536, plus near perfection (one spare square) just before 32768, 32768+16384, 32768+16384+8192, ... . [5] The low probability is supported by optimal solutions for constrained boards reflecting that large tiles are effectively frozen. [3] For the same reasons, the probability of making a 131072 is expected to be extremely low with the need for perfection at 65536, 65536+32768, ..., and finally a 4 tile (10% probability) at the exact right time to complete the formation.
16384 8192 4096 32 2048 1024 512 16 256 128 64 8 2 2 4 perimeter defense formation
A variation on the snake strategy (especially for larger tiles) is perimeter defense formation (PDF), which leaves the bottom part plus the right column (or a rotation or reflection of this) free from large tiles. In the snake strategy, one generally avoids moving down (if the large tiles are at the top), but PDF, especially at near full board, can allow all four movement directions. PDF gives somewhat higher success probabilities for AI, but many humans use the snake strategy (finding it more intuitive), as the probability of getting 32768 is still high (under near perfect play). [3]
AI strategy uses expectimax search up to a certain (variable) depth, plus transposition tables to avoid duplication. Analogously to endgame tablebases, tables are used to estimate success (for building a large enough tile without destroying the configuration) in appropriate positions with many large tiles. A position evaluation function can favor empty squares, having a large number of merge possibilities, placement of larger tiles at the edge, and monotonicity for tile sizes, especially for larger tiles. [6] [7] The parameters are optimized by a search for better parameter values; some papers [8] used temporal difference reinforcement learning.

The highest total score section is still not correct; it says "Therefore, the highest theoretically possible total score would be 1,835,012 if only 2s appear, and half this value in the case of 4s only." As the table shows, if you get a 131072 tile (from only 4s appearing), you could get a score as high as 1966080. In fact, you could build up the earlier tiles using 2s to score even higher.
Besides, someone should add in the code that the player gains 4 points if the tile generator would choose that tile so the player is not cheated for any points. — Preceding unsigned comment added by 84.202.189.96 ( talk) 20:13, 2 July 2014 (UTC)
Thank you. Mpozar ( talk) 23:18, 9 May 2014 (UTC)
The highest score possible is 3,932,100 and could be achieved as follows:
Only 2s appear until the board is filled with the following tiles:
{65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 2, 2}
At this point, the 2 2s could be merged. If a 2 appears, the game is over - the board is full and no merges are possible. However if a 4 appears, the tiles would then be:
{65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 4, 4}
Merging could then continue, allow the user to get a 131072 tile. Assuming all subsequent new tiles were 2s, the user could end up filling the board with:
{131072, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 2, 2}
At this point again the 2 2s could be merged, but the next tile would have to be a 4 or the game would be over. If a 4 appears, the tiles would then be:
{131072, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, 4, 4}
Merging could then continue, allowing the user to get up to a 65536 tile (with the 131072 tile remaining).
Gameplay could continue in this fashion, where each time the board gets full, 2 2s can be merged, and the next tile must be a 4 to prevent the game from ending. Ultimately the user would end up with:
{131072, 65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 4, 4}
After merging the 4s into an 8, either a 2 or a 4 would appear, and the game would end with the board:
{131072, 65536, 32768, 16384, 8192, 4096, 2048, 1024, 512, 256, 128, 64, 32, 16, 8, (2 or 4)}
Total score from merges that created each tile:
Tile | Accumulated Score |
---|---|
131072 | 1966080 + 131072 - 4 |
65536 | 983040 - 4 |
32768 | 458752 - 4 |
16384 | 212992 - 4 |
8192 | 98304 - 4 |
4096 | 45056 - 4 |
2048 | 20480 - 4 |
1024 | 9216 - 4 |
512 | 4096 - 4 |
256 | 1792 - 4 |
128 | 768 - 4 |
64 | 320 - 4 |
32 | 128 - 4 |
16 | 48 - 4 |
8 | 16 - 4 |
Total: 3,932,100

The result of the move request was: no consensus. Both the original and modified proposals appear to deviate from the guideline naming convention for video games. While guidelines are always open to exceptions, no compelling argument for the exception appears in the discussion below. Xoloz ( talk) 16:15, 20 June 2014 (UTC)

Anyone have a good reference on the tile spawn algorithm? It does not appear to be "random".-- Nowa ( talk) 01:38, 6 July 2014 (UTC)
It is random... just a random empty spot. 71.71.71.105 ( talk) 01:52, 23 August 2014 (UTC)
Of course this is not a video game guide, but should there be a sentence or two on basic strategy, or links to high-quality further discussions of strategy?
Came here via the reassessment request in the talk page template. Leaving this as C-class, though even that's pushing it. Some ideas for improvement below:
The article repeatedly mentions that Gabriele Cirulli does not make money on the game, but this is no longer accurate.
His official iOS version of the 2048 game: > https://itunes.apple.com/us/app/2048-by-gabriele-cirulli/id868076805 now includes advertising, and users must pay $0.99 to remove the advertising.

I'll make an initial review of this by the end of the week. Grabbing it now as it's a game I've spent plenty of time on. I see that the nominator hasn't made many edits to the article but it's not in a quickfail state. I do, however, see sourcing which will need serious improvement if this is to pass—as a couple of examples, student newspapers are not appropriate sources, nor are blogs, and nor is the primary source of DuckDuckGo. Conversely, once all the bad sources are stripped out, to ensure breadth and depth of coverage we'll want to make sure we're including as many reliable sources as exist. — Bilorv ( talk) 23:17, 15 July 2020 (UTC)
Referencing:
Clones written in C++ and Vala are available. There is also a version for the Linux terminal.has only primary sources. It needs either secondary sources, or removal if no secondary sources have discussed this code—otherwise there is no evidence of significance (I could write a version in Brainfuck but that wouldn't be information suitable for Wikipedia).
Content:
The game can only last a finite amount of moves, and the theoretical limit for the highest tile on a standard 4x4 board is 131,072.Says who? This isn't routine calculation.
This is perhaps more work than I expected from a first viewing and it may be too early to get this article to GA. In all honesty, I think the current article is C-class (or possibly Start-class) rather than B-class in quality. Let's see if we can get it up to B-class at least over the course of the review.
I'm leaving the article On hold and the review will be failed in seven days if there is not substantial progress in the referencing quality. If there's substantial progress then we can continue onwards with more low-level details. Even if the review fails, I'm interested in helping improve this article. — Bilorv ( talk) 15:53, 20 July 2020 (UTC)
Hi Dgpop, I saw that you're editing the page at the same time I am. I'm trying to get it to pass a GA this time around, and I'm following the suggestion left on the TP. I'm just following the suggestions left on the previous GA review (about six months ago). Are you also planning to do so? If so, then we could do a joint nomination or something if possible. One more thing — the picture being that large just don't work on a laptop, it's too big and the text does some funky things, so I'm undoing those, hope you don't mind.

Hello, I am planning on reviewing this article for GA Status, over the next couple of days. Thank you for nominating the article for
GA status. I hope I will learn some new information, and that my feedback is helpful.
If nominators or editors could refrain from updating the particular section that I am updating until it is complete, I would appreciate it to remove a edit conflict. Please address concerns in the section that has been completed above (If I've raised concerns up to references, feel free to comment on things like the lede.)
I generally provide an overview of things I read through the article on a first glance. Then do a thorough sweep of the article after the feedback is addressed. After this, I will present the pass/failure. I may use strikethrough tags when concerns are met. Even if something is obvious why my concern is met, please leave a message as courtesy.
Best of luck! you can also use the {{done}} tag to state when something is addressed. Lee Vilenski ( talk • contribs)
Please let me know after the review is done, if you were happy with the review! Obviously this is regarding the article's quality, however, I want to be happy and civil to all, so let me know if I have done a good job, regardless of the article's outcome.

The "Strategy and AI" section that I added (see this
revision) was removed by Dgpop. I feel strongly that its content is important. The most remarkable part about the game that a casual player is not likely to know (or believe) is the achievability of larger tiles, including that with over 80% probability, one can achieve a 32768 tile. The strategic depth has both spawned a loose community of expert human players, and made the game of interest to AI researchers. And the featured article nomination was declined largely due to absence of discussion of scholarly works related to 2048 strategy and AI. However, I will let other editors re-add the section, perhaps partially or in a revised form.
16384 8192 4096 2048 128 256 512 1024 64 32 16 8 2 2 4 snake
A common strategy is to build a snake from the highest to the lowest tile. Despite its name, certain reorderings are fine: For each row in the figure, we can independently set whether the numbers increase to the left or to the right; and (for example) "32 16 8 64" also works.
After learning the snake strategy, many casual players routinely get 2048 (thus winning the game) and 4096, but struggle to get 8192. The requirement to move can shift big tiles, which is often hard to recover from. And out-of-order tiles (especially larger tiles and in the middle of the board) deprive the player of the needed space. However, despite the random element, planning ahead can be remarkably effective, with a number of expert players, and several strong AI.
Using current (as of 2022) AI, [3] the probability of making a 16384 tile is over 95% (and likely over 98%). The probability of making a 32768 tile is over 3/4, and under perfect play expected to be over 80%. The probability of making a 65536 is over 3%. After some near misses, in 2022, 65536 was finally achieved by a human. [4]
To reach 65536, the snake or PDF (described below) at the end would occupy every single square (unless one gets a 4 at the end). The optimal probability for 65536 is expected to be low due to the need for perfection just before 65536, plus near perfection (one spare square) just before 32768, 32768+16384, 32768+16384+8192, ... . [5] The low probability is supported by optimal solutions for constrained boards reflecting that large tiles are effectively frozen. [3] For the same reasons, the probability of making a 131072 is expected to be extremely low with the need for perfection at 65536, 65536+32768, ..., and finally a 4 tile (10% probability) at the exact right time to complete the formation.
16384 8192 4096 32 2048 1024 512 16 256 128 64 8 2 2 4 perimeter defense formation
A variation on the snake strategy (especially for larger tiles) is perimeter defense formation (PDF), which leaves the bottom part plus the right column (or a rotation or reflection of this) free from large tiles. In the snake strategy, one generally avoids moving down (if the large tiles are at the top), but PDF, especially at near full board, can allow all four movement directions. PDF gives somewhat higher success probabilities for AI, but many humans use the snake strategy (finding it more intuitive), as the probability of getting 32768 is still high (under near perfect play). [3]
AI strategy uses expectimax search up to a certain (variable) depth, plus transposition tables to avoid duplication. Analogously to endgame tablebases, tables are used to estimate success (for building a large enough tile without destroying the configuration) in appropriate positions with many large tiles. A position evaluation function can favor empty squares, having a large number of merge possibilities, placement of larger tiles at the edge, and monotonicity for tile sizes, especially for larger tiles. [6] [7] The parameters are optimized by a search for better parameter values; some papers [8] used temporal difference reinforcement learning.
