    Frequently asked questions

    How many puzzles are there?
    115 puzzles across 13 categories at three levels: Warm-up, Solid and Sweaty. Every one comes with step-by-step working, not just an answer.
    Is it free?
    Yes, completely free, no signup, and it runs in your browser.
    Is anything stored or uploaded?
    Nothing is uploaded or sent anywhere. Your player names, scores and place in the round are saved in your own browser only, so an accidental tab close does not wipe the game. Reset everything clears it.
    How many people can play?
    Two to four. Names are editable, so use real ones.
    Can I choose the puzzles?
    Set a difficulty, narrow the categories with the filter, or open All questions to browse the whole bank and jump straight to any puzzle.
