The coach

Grandmaster strength, gentle delivery.

The engine runs entirely on your device — no server, no waiting — and plays at the level of the strongest programs. The coach turns that strength into teaching.

  • ✓A word at the right moment. Ask for a hint, or let the coach step in before a blunder becomes a habit.
  • ✓Every game, debriefed. Post-game analysis walks your key decisions, shows the better play on the board, and explains the idea behind it.
  • ✓Progress you can see. A rating built on the quality of your decisions — not just whether the dice were kind.

No lectures. A 54-stop Adventure carries you from your first roll to real doubling-cube judgement, one bite-sized challenge at a time — and the Daily Challenge gives you a fresh position to argue with every morning.

  • ✓Find the best move — classic positions, graded instantly, explained properly.
  • ✓Should you double? The decision the app is named for gets its own trainer.
  • ✓One a day keeps the blunders away. A daily position, a streak worth keeping.

The house rules

Designed like an object, not an app.
