WHAT YOU CAN DO
PUZZLES
• Mate in 1, 2 and 3: from beginner to tricky. Any move that really works counts, not just one answer.
• Daily Puzzle: a new one every day. Build your streak.
• Puzzle Rush: 3 minutes, 3 strikes. Beat your best.
• Ghost Race: 90 seconds against a ghost of your own best run.
• Streak: no clock, keep going until your first miss.
• Themes: practise forks, pins, back-rank mates and more.
• Coordinates: a 30-second drill to learn the board.
PLAY AND LEARN
• Quick Game: a full game against the computer. 8 levels, play White or Black. It saves after every move.
• Win the Endgame: start from a winning position and finish the job.
• Lessons and Learn the Pieces: short, step-by-step practice for beginners.
• Hints that teach: a nudge first (which piece), then the idea, then the move. You also get a short explanation after every solve.
TRACK YOUR GROWTH
Streaks, badges, weekly progress, and a list of your mistakes to retry.
MADE FOR EVERYONE
6 board themes, 4 piece styles, light and dark mode, colour-blind-safe colours, large text, reduced motion, and keyboard move input.
