Sudoku Brain Blocks is a fun block-fitting puzzle game that uses a 9x9 sudoku-style board. Place the blocks on the board and try to fill horizontal and vertical lines, or the shaded blocks of 3x3 squares. How long can you keep playing?
Drag the three blocks that appear at the bottom of the screen and place them on the board. The aim is to fill complete rows, columns, and the blocks of 3x3 squares. This will make the blocks vanish, freeing up precious space for new blocks.
Plan your moves carefully. Every time you’ve placed your three blocks onto the board, three new ones will appear. If you run out of space to fit any of the blocks, you lose the game.
