About this game

A wood-block puzzle combining Sudoku grid logic with polyomino piece placement. Place 3 shapes per turn, clear rows, columns and 3x3 boxes.

How do you play Woodoku?

You receive 3 wooden block shapes each round. Drag them onto the 9x9 grid. Complete any full row, column, or 3x3 Sudoku box to clear those cells and earn points. When all 3 shapes are placed, a new round of 3 shapes appears.

What is the difference between Woodoku and Sudoku?

Classic Sudoku fills numbers 1-9 so each row/column/box contains all digits exactly once. Woodoku uses polyomino block shapes instead — you clear by COMPLETING (fully filling) any row, column, or 3x3 box, with no number constraints.

How do you get a high score in Woodoku?

Clear multiple lines and 3x3 boxes with a single placement for combo bonuses. Box clears score 3x more than line clears. Build streaks by clearing on consecutive placements, and keep the grid center open for flexibility.

Is Woodoku free to play?

Yes, Woodoku is completely free to play online at GameZipper.com. 30 hand-crafted levels across 5 difficulty tiers, no download or registration required.
