2048 — Crystal Tile Number Merge Game

Yes, completely free with no sign-up, no paywalls and no move limits — play as many rounds as you like. The board renders as translucent crystal-style tiles that crack and shatter on merge, but the underlying rules match the original 2048 exactly.

The game runs on a 4×4 grid — slide every tile in one direction using the arrow keys, WASD, or a swipe gesture, and each tile slides as far as it can until it hits the edge or another tile. Two tiles with the same number merge into one worth their sum (2+2=4, 1024+1024=2048), and each merge adds that new value straight to your score. Reach a 2048 tile to win, or keep playing past it for a higher score, and a one-step undo button lets you take back your last move.

Yes. Your board layout, current score, and win state are written to local storage after every move, and your all-time best score is tracked separately — refreshing or closing the tab picks up exactly where you left off.

After a run ends, if you've set a new personal best you can submit your name and score to the shared world leaderboard, which keeps the top 50 highest scores from every player. Runs that don't beat your existing best aren't offered a submit prompt, so the board stays reserved for genuine improvements.

Yes. The 4×4 board is fully responsive with large touch targets, and you swipe in any of the 4 directions (up/down/left/right) to move tiles — no keyboard needed. The crystal tile lighting and shatter effects render smoothly on phone-class GPUs.

The core merge rules are unchanged, but tiles are rendered as semi-transparent crystal blocks that visibly crack and scatter shards on every merge instead of flat colored squares. This version also adds a one-step undo button, automatic save/resume, and a global leaderboard for the top 50 scores — none of which the original 2048 included.
