Mini Speed Sudoku
Three rounds in one run: 4x4, then 6x6, then 9x9.
Fastest total completion time wins the leaderboard.
01 /How to Play
- Complete three rounds in order: 4x4, then 6x6, then 9x9.
- Each grid follows standard Sudoku rules for its size and box layout.
- Round timer runs while solving each board; your final score is total time.
- Conflicts are highlighted in red so you can fix invalid entries quickly.
- Lower total time ranks higher on the global leaderboard.
02 /The Science
This mode combines working-memory constraint solving with sustained processing speed across escalating problem scales. Switching from 4x4 to 6x6 to 9x9 increases search space and executive load while preserving the same core rule set.
