Reversi Coach

Most Reversi apps give you an opponent. This one gives you a coach.

Play a game, and Reversi Coach reviews it move by move — your accuracy score,
every inaccuracy, mistake and blunder, and for each one, the move you should
have played and why.

LEARN THE GAME PROPERLY
90 lessons across 15 courses, from the rules to championship analysis:
• The board, flipping, legal moves and passing
• Corners, danger squares, and why more discs early is a trap
• Mobility, stability, parity, and the endgame count
• Edge tactics, diagonals, openings, and master games explained
Lessons are interactive — you play the positions, not just read about them.

A HINT WHEN YOU WANT ONE
Stuck mid-game? Ask the engine. It answers instantly, and you can set how hard it
thinks when grading your finished games.

IT ALL RUNS ON YOUR PHONE
No account. No sign-in. No ads. No internet required — the engine, the lessons
and your history live on your device, and your games are never uploaded anywhere.

FREE TO START
Levels 1–20, every lesson and every puzzle are free. One payment unlocks levels
21–60 forever. No subscription.
