📈 ELO RATING SYSTEM
━━━━━━━━━━━━━━━━━━

Every puzzle has its own difficulty rating, just like a chess player. Solve a tough one and yours climbs; miss an easy one and it dips — the same system used by FIDE and Lichess.

The app automatically suggests puzzles matched to your current rating, so you're always challenged but never overwhelmed.

━━━━━━━━━━━━━━━━━━
🔥 COMBO SYSTEM
━━━━━━━━━━━━━━━━━━

Solve consecutive puzzles to enter combo mode:
• 3 in a row → ON FIRE
• 5 in a row → BLAZING
• 10 in a row → UNSTOPPABLE
• 25 in a row → LEGENDARY

Each tier rewards bonus rating points. Lose the streak, lose the bonus.

━━━━━━━━━━━━━━━━━━
📅 DAILY PUZZLE
━━━━━━━━━━━━━━━━━━

A handpicked puzzle every day, identical worldwide. Solve it to extend your daily streak, share your result Wordle-style, and earn streak achievements.

Optional notifications remind you when your streak is at risk.

Recent changes:
• Fixed: replaying a puzzle no longer changes your rating. Each puzzle now counts only on its first attempt.
• Ratings inflated by that bug have been recalculated — your solved puzzles are kept.
• Replays show a "Practice" badge, so you know the result won't be scored.
• The timer now resets properly when you tap Retry.
• Updated for Android 16.
