Ultimately, however, your survival toward the end of the game relies heavily on the random tile spawns working out in your favor one poorly placed tile can spell the doom of your game. Some of these tips are fairly well-known - and were even coded into the AI as heuristics - but I figured it's good to cover the bases.įollowing these tips will undoubtedly help you improve your game and - hopefully - beat 2048. Below, I'll outline 4 useful playing tips that the AI adopted to beat 2048. To get a better understanding of how the AI managed to rack up such a high score, I analyzed its playing strategy on its highest-scoring game. At that rate, the AI would theoretically reach the 131,072 tile (the theoretically largest tile) in about 65,500 moves - roughly 2x the number of moves it ended up lasting for - if the random tile spawns played out in its favor. For example, the AI reached the 16,384 tile in about 8,000 moves. What's especially curious about the AI's progression is that it tends to reach tile X in about (X / 2) moves. In that instance, the AI beat the game in only 973 moves, which is about average for the AI. (Though it's theoretically possible, if you're lucky.)įor the rest of this post, I'll be looking at the game where the AI reached the high score of 839,732. In 1/3 of the games, the AI astonishingly reached the 32,768 tile, though it wasn't able to make it much further past that. The AI reached the 2,048 tile - and even the 4,096 tile - in all 1,000 games, and reached the 16,384 tile in a large majority of them. Perhaps even more impressive is how consistently the AI beats 2048. Most instances ended with a score around 390,000 and a 16,384 tile, but the best instance built a 32,768 tile and stayed alive long enough to reach a score of 839,732.Īs far as I know, this is the highest score achieved in 2048 without undos. The worst instance achieved a score of 35,600, but even that instance managed to build the 2,048 tile and beat the game. Some games ended in a few minutes due to a series of unfortunate random tile spawns, while others nearly lasted 4 hours and reached scores previously thought impossible. Like a multi-armed genius, the AI played 1,000 games of 2048 simultaneously without a hitch. it crushed every human record in 2048 that I could find.īelow is a video of the first 20 seconds of the AI hacking away at the game, mashing and merging tiles at superhuman speeds that we only wish we could match. Much to my surprise, it not only beat 2048. It didn't take me long to find out that there's already some pretty good AIs out there, so I picked up the best 2048 AI I could find and fired several instances of it to see what it could do. Last week, I picked up 2048 for the first time and - true to my nature - I started designing an AI to beat the game for me the following day. By now, we've all heard of the addictive tile-mashing game called 2048.
