About

2048: slide the grid, equal tiles merge and double, a new tile appears each move. Keep going until you make 2048 — or run out of room. Arrow keys on desktop, swipe on touch.

How it works

Each direction maps to four lines of indices; every line is compressed and its equal neighbours merged (one merge per tile per move), then written back. A move that changes anything spawns a 2 or 4. Best score lives in localStorage under kaspirius:2048:best. No backend.
