How to play
Sudoku Blocks blends classic sudoku logic with satisfying block-puzzle gameplay. Fill the 9x9 grid so that every row, column, and 3x3 box contains the numbers 1-9 with no repeats — or place blocks to clear complete lines, depending on the mode. Either way, it's pure number logic heaven for puzzle lovers!
Tips
- Start with the most-filled areas — rows, columns, or boxes with many numbers already placed offer the easiest deductions.
- Use the process of elimination — if a number can't go anywhere else in a box, that's where it belongs.
- Scan for naked singles — cells where only one number is possible are free wins.
- Don't guess — every sudoku puzzle is solvable by logic; guessing creates contradictions later.
- Take breaks on hard grids — fresh eyes spot patterns that tired ones miss.
