Reti: Chess Puzzle Trainer

Reti is the tactical training app for chess players who want to improve for real.

Every session brings puzzles calibrated to your level, delivered at exactly the right moment — no mechanical repetition, no artificial difficulty.

♟ TRAIN LIKE A MASTER

• Adaptive puzzles: the FSRS system learns from you and presents each exercise right when your brain is ready to retain it.
• Real-time ELO: track your progress with a candlestick chart. Watch your rating grow session by session.
• Puzzle of the Day: a special puzzle every morning to sharpen your mind before the day begins.
• Smart hints: if you get stuck, the compass guides you without giving away the answer.

🏰 THE KINGDOM — PLAY WITH PURPOSE

Earn crowns, crystals and chests by solving puzzles correctly. Lives give you just the right amount of play time: enough to improve, without the burnout of infinite scrolling.

📈 REAL PROGRESS TRACKING

• Session traffic light: see at a glance whether you've trained enough today.
• Visual history: every puzzle you've solved stays in your profile with a mini board.
• Daily streak: build the habit with a streak earned through quality, not quantity.

🌍 AVAILABLE IN 4 LANGUAGES
Español · English · Français · Português

Inspired by Richard Réti (1889–1929), the hypermodern chess genius who proved a king can chase two hares at once.
