Shapedoku Guides
Everything you need to get more out of Shapedoku, the shape-based Sudoku you can play free in your browser. These guides cover the difficulties and the gentle Beginner tutorial, the Daily Challenge and streaks, challenge modes like Speed, No Mistakes and Perfect Run, pencil Notes with smart cleanup, hints that explain why a shape fits, XP, levels and rank titles, and how to play offline or across devices.
Shapedoku keeps the exact rules of classic Sudoku and swaps the numbers 1 to 9 for nine glowing shapes, which makes a busy board easier to scan and friendlier to colorblind players. Everything here is honest and practical, meant to help you play better rather than to sell you anything.
