Dominosa

About the game

A browser adaptation by Zarocer.

Dominosa Zarocer brings the classic Dominosa puzzle to your browser. A grid holds the numbers from a complete domino set, but the boundaries between the pieces are missing. Reconstruct each domino by pairing two cells that touch horizontally or vertically. Every number combination must appear exactly once: 1–2 and 2–1 count as the same piece. Study the numbers, rule out repeated pairs, and revise your placements until the entire board is covered. Practice mode offers three difficulty levels, while the daily challenge provides a shared puzzle that changes at 00:00 UTC. There is no countdown, so you can think at your own pace, pause, and continue a saved game in the same browser. Play with a mouse, touch screen, or keyboard. Hints help you move forward when stuck and mark the attempt as assisted. Times and statistics are kept locally when browser storage is available. Global ranking remains disabled until the official integration is completed.

Controls

Choose a practice difficulty or open the daily challenge. Select one cell and a horizontal or vertical neighbor to place a domino. Use each number pair exactly once. The order of the numbers does not matter. Select a placed domino to remove it and try a different pairing. Cover every cell without overlap to win. You can pause and resume your game. On a keyboard, use arrows to navigate, Enter or Space to select, and Escape to cancel or pause.
