This app has been updated by Apple to display the Apple Watch app icon. This version is totally rewritten in Swift. Try it out and let me know of any new features you'd like to see. Happy backgammoning!

Fixed bug where a checker is flipped on edge at the start of a new game.

• Added native support for iPad. • Refined the graphics to look good on a larger screen.

• Hint feature. Can't decide what to do? Just ask, and iGammon will show you step by step. It's a great way to learn! • Tutor mode. Tells you when you've made a mistake. Then you can go back and think some more, ask for a hint, or make your own play anyway. • Orientation lock. Keeps the board from rotating when you turn the phone.

* Table stakes. You and your opponent start with an equal number of chips and keep playing until one player collects all the chips. Use doubling cube, optional Jacoby rule, or optional Beavers rule. Start with 5, 10, 15, 20, 25, 50, 100, or 500 chips each. * Match play. Be the first player to reach a specified number of points. Use doubling cube and optional Crawford rule. Match lengths can be 1, 3, 5, 7, 9, 11, 13, 15, 17, 21, 25, or 99 points. * Choose direction of play. Bear off to the left side or to the right side. * Reverse colors. Play using either the red or the yellow checkers. * Human-vs-human play. Use your iPhone or iPod touch as a traveling backgammon board. * Auto finish game. Have computer finish the game for you.

Doubling cube -- just slide the cube over to your opponent's side of the board when you want to double the stakes. Landscape mode -- game switches to landscape mode when iphone/ipod is rotated. Strong AI -- now there are four levels of play: "Cautious," "Wild," "Advanced," and "Expert." Many minor features to improve the playing experience -- touching the dice to switch their order, option for auto bearoff, fast animation.
