GatherSpace

Move every tile together, combine matching numbers, and make space for the next turn.

Classic play uses a 4 × 4 board where each valid swipe shifts tiles toward an edge. Matching neighbors merge into a higher value, and one small tile appears only after the board changes. Plan ahead: a merged tile can only merge once during a move. The run ends when a full board has no legal merge.

Explore 50 repeatable challenges across target, barrier, and open-corner goals. Each puzzle has a fixed starting layout and predictable tile sequence, so success depends on your choices rather than a changing spawn roll. Boards range from 3 × 3 to 4 × 4, with move limits on selected puzzles.

Undo your most recent move once per run. Pause, review your highest tile, score, move count, and merge summary, then return to the board or begin another puzzle. A hands-on 3 × 3 guide introduces whole-board movement, merge limits, and ways to preserve open cells.

Adjust swipe sensitivity, tile number size, merge timing, sound cues, visual texture hints, and light or dark appearance. Personal scores, preferences, challenge progress, and saved games remain on your device. Core play does not require an internet connection or an account.
