Drop blocks to fill rows, columns and 3x3 boxes. Endless block sudoku puzzle.
Blockdoku is a relaxing block puzzle with a sudoku twist. Drag blocks onto the 9x9 grid and clear a whole row, a whole column, or a 3x3 box to score. Line up several clears at once for a big combo -- the more you clear in one move, the higher the multiplier. Simple to learn, endlessly replayable. No timer, no pressure -- just you, the grid, and your best score. HOW TO PLAY You get three blocks at a time. Drag them anywhere they fit. Fill any full row, column or 3x3 box and it clears. When none of your three blocks fit, the game ends -- so plan ahead and keep space open.
