Rules

• Two players work on the same puzzle at the same time.
• You see each other's moves as you play.
• Score by filling in cells correctly.
• Lose points for mistakes.

Scoring

• Filled cells: ✅ 1 point each
• Mistakes: ❌ -2 points each
• Score example: 5 (-4) means: total score is 5 after subtracting 4 points for mistakes, meaning the player filled 9 cells correctly and made 2 mistakes.

You can go into negative points.

The game ends when the puzzle is completed — the player with the most points wins. In the event of a tie, the player with fewer mistakes wins. If mistakes are tied too, the game ends in a tie.
