Block Sudoku
Tiles puzzle. Place blocks. Clear rows, columns and boxes.
Block Sudoku is a calm but clever block puzzle. Drag colourful pieces onto a 9 x 9 board and fill a row, a column or a 3 x 3 box to clear it, just like the groups in a sudoku grid. Plan ahead, chain clears together and watch the board come alive.
Drag a piece
You get three pieces at a time. It floats above your finger so you can always see where it will land.
Fill a row, column or box
Complete a line or a 3 x 3 box and it clears with a burst of animation.
Don’t run out of room
If none of your pieces fit, you lose a life.
