About this game

How Twenty Forty-Eight works

Twenty Forty-Eight slides number tiles across a 4×4 board. Equal values combine, but the direction of a move determines which pairs meet first.

Objective and win/loss conditions

Build a 2048 tile to reach the target; larger tiles remain possible if you continue. The board is over when it is full and no horizontal or vertical neighboring pair can merge. A move that changes nothing does not spawn a new tile.

How it plays

Slide with arrow keys, WASD, or a swipe. All tiles travel as far as they can in that direction. Equal neighbors merge once per move. After a successful slide, a new tile appears in an empty cell: 2 with 90% probability or 4 with 10%.

For example, before the new tile spawns, sliding the row 2, 2, 2, 2 left produces 4, 4, empty, empty. It does not produce 8 in one move because newly merged tiles cannot merge again until the next slide. A row of 2, 2, 4, empty similarly becomes 4, 4, empty, empty.

Scoring and strategy

Each merge adds the value of its resulting tile to the current score. The four-twos example earns 4 + 4 = 8 points. The persistent best, however, is the largest tile reached, not the run’s point total.

Keeping a large tile near one corner can make a descending chain easier to maintain. Before changing direction, check whether the slide separates a useful pair or traps a smaller tile behind a larger one. Random spawns mean this is a planning habit, not a guarantee of reaching 2048. Undo can restore a previous board.

Local save data

nocharge:2048:best-tile remembers the highest tile reached in this browser’s localStorage. It does not store the current score, full grid, or undo sequence. Reloading begins a new board with the saved best tile still available as a personal reference.
