Play the daily board
The board below is identical for every player worldwide until midnight UTC. Highest verified score wins.
How to Play
Swap any two numbered tiles, make lines of 3+, maximize your score, and decide when to end the run and submit.
- 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 any tile, then select any other tile anywhere on the board. The two tiles swap positions. Clicking the same tile again deselects it.
- Matches are horizontal or vertical only. Any horizontal or vertical line of 3 or more identical numbers can trigger a clear, but if those lines join, they clear as one connected group. Diagonals do nothing.
- No gravity and no refill. Cleared tiles become permanent gaps. Nothing falls and nothing new appears.
- Groups score by size. 3 = 100, 4 = 160, 5 = 250, 6 = 380, 7 = 540, 8 = 730, 9 = 950.
- Every swap matters. When you end the run, your final score deducts 10 points per swap used.
- Perfect clears are special. Clearing the entire board awards a flat +400 Perfect Clear bonus.
- Swaps are global. You are not limited to adjacent tiles. Any two non-empty tiles can be swapped.
- Shape bonus matters. If one cleared group spans both horizontal and vertical directions, that group gets a 20% bonus.
- You do not need to clear the board. Your daily standing is based on the highest verified score you build on that seeded map before you reset and try again.
- You decide when to end the run. Use End Run when you want to lock in your score and submit it for verification. The game can warn you if either an immediate scoring swap or a future scoring path still exists.
- Fragmentation is the constraint. Because empty gaps cannot be swapped, isolated leftovers can strand future scoring chances.
- Multi-clears are powerful. One swap can score multiple separate disconnected groups at once. Each connected group scores once by its total size, so a joined T, cross, or bent cluster counts as one group, not multiple overlapping lines. If one swap clears two separate groups, it also awards a flat +80 combo bonus.
- Server verification decides the leaderboard. The client helps you play, but submissions are recomputed by the server before they count.
- Runs are persistent until reset. Scrolling through the site does not reset your board. Use Reset Run when you want to restart the same daily board from scratch.
- The simplest way to remember the game: swap any two numbered tiles to make 3+, keep the board alive, and finish with the highest score possible.
