## What is 2048 (3x3, 4x4, 5x5) AI?

Classic 2048 puzzle game redefined by AI.

Our 2048 is one of its own kind in the market. We leverage multiple algorithms to create an AI for the classic 2048 puzzle game.

* Redefined by AI *
We created an AI that takes advantage of multiple state-of-the-art algorithms, including Monte Carlo Tree Search (MCTS) [a], Expectimax [b], Iterative Deepening Depth-First Search (IDDFS) [c] and Reinforcement Learning [d].

(a) Monte Carlo Tree Search (MCTS) is a heuristic search algorithm introduced in 2006 for computer Go, and has been used in other games like chess, and of course this 2048 game. Monte Carlo Tree Search Algorithm chooses the best possible move from the current state of game's tree (similar to IDDFS).

(b) Expectimax search is a variation of the minimax algorithm, with addition of "chance" nodes in the search tree. This technique is commonly used in games with undeterministic behavior, such as Minesweeper (random mine location), Pacman (random ghost move) and this 2048 game (random tile spawn position and its number value).

(c)Iterative Deepening depth-first search (IDDFS) is a search strategy in which a depth-limited version of DFS is run repeatedly with increasing depth limits. IDDFS is optimal like breadth-first search (BFS), but uses much less memory. This 2048 AI implementation assigns various heuristic scores (or penalties) on multiple features (e.g. empty cell count) to compute the optimal next move.

(d) Reinforcement learning is the training of ML models to yield an action (or decision) in an environment in order to maximize cumulative reward. This 2048 RL implementation has no hard-coded intelligence (i.e. no heuristic score based on human understanding of the game). There is no knowledge about what makes a good move, and the AI agent "figures it out" on its own as we train the model.

### 5/5 — Well made version of the classic

*2025-12-09, version 6.5*

This is one of the better versions of the 2048 game. It runs well and there are not a bunch of intrusive ads like some of the others.

### 5/5 — Lot’s of games

*2025-05-17, version 6.5*

In 2048, it’s not just that they’re more other games if you don’t feel like playing 2048.

### 5/5 — fun

*2025-05-06, version 6.5*

it’s fun

### 5/5 — 2048->4096->????

*2025-04-22, version 6.5*

Add 8192 please

### 3/5 — New games??

*2025-02-25, version 6.5*

Any chance of adding new games??

### 5/5 — Good games and tools

*2025-01-25, version 6.5*

Great but annoying you can’t pay to make ads go away

### 2/5 — Too many ads

*2024-09-19, version 6.5*

Game itself is fine, but popping ads are very annoying and their appearance are far beyond reasonable. I have no interest wasting time to watch stupid ads, deleted.

### 4/5 — Review

*2024-07-01, version 6.5*

I love this game! It would get 5 stars if there was less ads, but the game it self is great. There are 13 other mini games in this game and other things, like a full screen clock etc.

### 5/5 — love!

*2024-06-18, version 6.4*

this app is so good. i was searching for an app with the block puzzle featured in this app, but i wanted it to have other games too, as my phone doesn’t have enough storage for lots of apps. this app was perfect! i was searching for the block puzzle like the one in this game, but i also wanted to play the sort of “tetris” type game, where you drop blocks from up above as the blocks slowly move up to the line. still searching for a game like this, but this app was perfect

### 5/5 — 9.9 / 10

*2024-02-23, version 6.1*

Amazing multi use app! I do wish there was a time zone calculator though.
