Slide and merge tiles to reach 2048 - undo support, keyboard and swipe controls, best score saved in your browser
Basic rules: 2048 is played on a 4x4 grid of 16 cells. Each move pushes all tiles up, down, left or right; two adjacent equal tiles along the direction merge into one doubled tile, and the merged value is your score. The goal is to build the 2048 tile.
Merge constraint: each tile merges at most once per move. A row of [2,2,2] sliding left merges only the edge pair into [4,2]; [2,2,2,2] becomes [4,4], never chaining into an 8. To build big numbers, line equal tiles up before pushing.
Spawning: after every valid move a new tile appears on a random empty cell, about 90% a 2 and 10% a 4. Only real movement or a merge triggers a spawn; a direction that leaves the board unchanged is an invalid move that spawns nothing and is not counted.
Undo and resume: on top of the classic rules we add one-tap undo — the board and score before each valid move are remembered, so you can take one step back (undo never lowers your best). Progress is saved locally and auto-resumes on refresh, no login or network needed.
Winning and continuing: reaching a 2048 tile wins; you may keep going for 4096, 8192 and beyond, or stop and view your score. The game ends when the board is full and no move can merge anything. Score accumulates from merges, best only ever increases, and beating it triggers a celebration.
⚠️ This 2048 is a casual puzzle; scores and best records are stored only in your local browser, and rating text is for fun only.
