GammonGuide: Backgammon Coach

GammonGuide Coach now has a lower one-time price.

GammonGuide teaches backgammon the way strong players learn it: call the expert's move, then see how close you came.

A strong backgammon engine plays both sides of every game. When it's your turn, the game pauses and you decide. Move your own checkers, or just tap the one you think moves first. The engine then plays its move and grades yours: right, close, mistake or blunder.

PLAY EVERY DECISION • Full play: move the checkers yourself and submit the whole play. Rings show where each checker can land and how far it travels. • Quick play: tap the checker you think the expert moves first. One tap, one grade. • Play the computer: your moves stand, even the wrong ones, and you play the game out against the computer. Every play is still graded, and your wins and losses are kept. • The doubling cube: decide when to double, take or drop, and see what the engine would do. • Undo a move before you submit it.

SEE WHY • Why? explains the last round in plain language: what your play leaves open, how often the computer's best reply hits, and how often each play wins from there. • Replay acts the round out on the board while a voice walks you through it.

WATCH YOURSELF IMPROVE • Progress shows how often you blunder and whether that number is going down, game by game. • Opening Drill: practice the first move of the game with every opening roll, and build a streak.

GAMMONGUIDE COACH One in-app purchase unlocks Why? and Replay for every round, plus Previous games with playback. Everything else is free, and Why? and Replay work free for your first ten mistakes or blunders. One purchase covers your iPhone and iPad.

APPLE WATCH Play a whole game on your wrist, one tap per turn, with the same engine and the same grades. Requires Apple Watch Series 9 or later, or Ultra 2 or later, with watchOS 27.

PRIVATE BY DESIGN No accounts, no ads, no tracking. The engine runs on your device and works offline, and your games never leave it.

GammonGuide plays money games without the Jacoby rule.
