Shapedoku Challenge Modes: Speed, No Mistakes and More

Classic play

Classic is the heart of Shapedoku. You solve at your own pace with room for a few mistakes before the game ends. It is the best place to learn techniques, experiment and simply relax. If you are new, start here and stay a while.

Speed

Speed mode puts a countdown on the board. Finish before time runs out to win, and the faster you go, the better your score. It rewards quick scanning and confident placement, and it is a great way to push your recognition speed. When the clock gets low it pulses to keep the pressure honest.

No Mistakes

No Mistakes is a test of precision. A single wrong placement ends the run. There is no room to guess, so every move must be proven. It teaches the discipline of checking the row, column and box before you commit, which quietly makes you a better solver everywhere.

Perfect Run

Perfect Run is the purist's challenge. Finish with no mistakes and no hints, relying on nothing but your own logic. It is the achievement to chase once the other modes feel comfortable, and clearing one is a real badge of skill.

Daily Challenge

The Daily Challenge is one fresh puzzle each day, the same board for everyone. It is the perfect anchor for a daily habit and a friendly way to compare your time against other players. Keep coming back and your streak grows along with your skill.
