About this game
Crux turns chess tactics training into a daily habit you will actually look forward to.
Every puzzle is picked to match your level. As you solve, Crux tracks a separate rating for each tactical theme - forks, pins, skewers, mating nets, endgames and more - and serves the next puzzle right in your stride: hard enough to grow, fair enough to win.
KEY FEATURES
- Adaptive difficulty: a per-theme rating engine finds your sweet spot on every move.
- Personal AI coach: a short, personalized daily summary highlights your strengths and what to work on next.
- Deep stats: track your rating over time, accuracy, streaks, and your deliberation sweet spot.
- Spaced repetition: tricky themes come back for review until they stick.
- Compete: climb global and weekly leaderboards, or compare with friends.
- Challenge a friend: send a 5-puzzle duel and see who scores higher.
- Beautiful by default: bold, modern board themes and satisfying animations.
- A huge, ever-fresh library of puzzles across every motif and phase of the game.
Crux is free to play. An optional "Remove Ads" subscription removes interstitial ads and unlocks premium cosmetics.
Sharpen your tactics. Beat your yesterday.
