Failure is not the opposite of success, it is part of it.

WHAT IS IT?

Blunderzone turns your own games into practical chess training.

1. Import games from lichess.org or chess.com
2. Analyze them in stages: quick, normal, and deep analysis
3. Turn missed ideas into puzzles for game-based, quick, and memory training

New games are checked regularly, so training stays close to what you have just played.

I always make the same damn mistakes.

Why train from your own games?

• The positions match your openings, time controls, and practical habits
• You review your worst moments instead of solving unrelated puzzles
• The app keeps separate flows for daily game-based practice, fast sessions, and spaced repetition
