How to play and game rules
- Fill every cell with ○ (0) or ● (1). No row or column may contain three equal symbols in a row.
- Each row and each column must hold the same number of zeros and ones. No two rows may be identical and no two columns may be identical.
- Fixed cells (bold, gold) cannot be changed. Every puzzle has a single solution that can be deduced without guessing.
- Press a cell to cycle between empty, ○ (0) and ● (1). With the keyboard, Tab enters the board, arrows, Home and End move focus, and keys 0 and 1 set the value; Backspace or Delete clear the cell.
- Cells that break a rule get an orange border and a “!”, but the game still lets you place them. You win by completing the board without conflicts. Undo keeps up to 100 steps.
- Easy: 6×6. Medium: 8×8. Hard: 10×10. The daily game uses medium.
- Daily: one scored game per UTC date, changing at 00:00 UTC (19:00 in Panama). Unfinished games expire at the next challenge and finished games cannot be restarted.
- Unlimited games keep separate statistics. Only finished games count. Changing language preserves progress. Data stays in this browser and domain; clearing site data removes your history.
