What is Shapedoku?
Shapedoku is a free, shape-based Sudoku puzzle game. Instead of the numbers 1–9, every cell holds one of nine glowing shapes — a triangle, hexagon, circle, crystal, heart, diamond, square, crescent moon and lotus. The classic Sudoku rules still apply: fill every row, column and 3×3 box with each shape exactly once. The shapes make the board easier to read at a glance and friendlier for colorblind players, since each token is distinct by form as well as color.
Play instantly in your browser — no download and no login required. Sharpen your logic across four difficulties (Easy, Medium, Hard and Extreme), take on a brand-new Daily Challenge every day, jot down candidates with smart pencil notes, reveal a hint when you’re stuck, earn XP to level up, and climb the global leaderboards. Your progress saves automatically and the game works fully offline.
