Play the daily board
The board below is identical for every player worldwide until midnight UTC. Fewest verified swaps wins. If swaps tie, faster time breaks the tie.
How to Play
Swap any two numbered tiles, make lines of 3+, and clear the whole board in the fewest swaps you can.
- The board is always 9 by 9. Every daily board starts with the numbers 1 through 9 repeated 9 times each.
- Numbers are color-coded for faster reading. The number itself is what matters, while each number also keeps a consistent color to help you spot groups faster.
- Everyone gets the same board every UTC day. There is one seeded daily layout for all players. It resets at midnight UTC.
- Select one tile, then select another non-empty tile anywhere. Those two numbered tiles swap places. Swapping with empty spaces is not allowed.
- Matches are horizontal or vertical only. Any line of 3 or more identical numbers clears immediately. Diagonals do not count.
- Cleared spaces stay empty. Empty cells are permanent gaps and cannot be used in swaps.
- Your goal is to clear the whole board. The daily leaderboard ranks fully cleared runs by the fewest swaps used. Ties break by the fastest time, then earlier verified submission.
- The game ends automatically when the board is cleared. If you are signed in, your cleared run is verified and submitted automatically.
- Sound is optional. Use the Sound On/Off button if you want subtle swap, clear, and finish sounds.
- The simplest way to remember the game: swap any two numbered tiles, clear every tile, and finish in as few swaps as possible.
