Blunderzone

Blunderzone helps chess players train the positions that matter most: the critical moments from their own games.

Connect a chess account, import your recent games, and let Blunderzone turn missed ideas into practical training. Instead of solving random puzzles, you revisit the patterns, openings, time controls, and habits that actually appear in your games.

Training modes:

• Game Tactics: review puzzles generated from mistakes in your own games.
• Quick Tactics: solve fast 10-puzzle sessions for speed and pattern recognition.
• Memory Training: use spaced repetition to keep important tactical patterns fresh.
• Game Review: inspect analyzed games and the moments behind your training.

Blunderzone is built for players who want deliberate chess improvement, not another generic puzzle feed. Your mistakes become a training plan, and the app keeps bringing them back until the patterns are easier to see over the board.
