Puzzoku is a logic puzzle game that blends the spatial thinking of Tetris with the number skills of KenKen. Fill the grid by dragging arithmetic pieces into place. Every row and column must contain each number exactly once — and every piece must satisfy its target sum, difference, product, or quotient. Simple to learn. Genuinely hard to master. HOW TO PLAY Each puzzle presents a grid divided into irregular pieces. Every piece shows a number and an operator — your job is to drag the pieces onto the board so that each row and column contains no repeated numbers, and every piece's cells produce the correct result. As pieces lock into place, the grid comes alive. When the last piece fits, you've solved it. 99 CAMPAIGN LEVELS Work your way through a hand-crafted campaign that starts gentle and gets brutal: • Levels 1–10: 4×4 grids, addition only — perfect for learning the ropes • Levels 11–30: 5×6 grids, introduce subtraction and multiplication • Levels 31–60: 7×8 grids, all four operators, increasingly complex shapes • Levels 61–99: 9×10 grids, irregular shapes — rings, crosses, diamonds, frames — and no mercy ENDLESS GAME GENERATOR Not in the mood for campaign? Build your own puzzle. Pick a grid size from 4×4 up to 10×10, choose which operators to include, and hit Start. Addition-only makes for a relaxed challenge; all four operators on a 10×10 grid is a serious test of concentration. ACHIEVEMENTS & STREAKS Over 30 achievements track your journey — from placing your first piece to completing 500 games without hints. Keep your daily win streak alive to unlock Streak badges, from On a Roll (3 days) all the way to Century Streak (100 days). Every win counts. SMART HINTS Stuck? Tap the lightbulb for a nudge. The hint system highlights a misplaced piece and animates exactly where it can go — starting with the piece that will unblock the most options. Each hint adds 30 seconds to your time, so use them wisely.
