Backgammon

You have the light checkers. The computer has the dark ones. Each of you has 15. The goal is to bring all 15 of yours around the board to your home corner (the bottom right), and then take them off the board. The first side to take all 15 off wins.

Your checkers travel along the top from right to left, then along the bottom from left to right. The computer travels the other way around.

Tap Roll the dice. Each die is a number of steps for one checker. Tap a checker to pick it up. Spots it can go to get a dashed outline. Tap one to put it down. Tap the checker again to put it back. Use each die once. If you roll a double, you play that number four times.

A spot with two or more checkers of one side is blocked for the other side. A lone checker can be hit: if the other side lands on it, it goes to the bar in the middle and has to start again. A checker on the bar must come back in before anything else moves. It comes in on the far end of the board, on the spot that matches the die.

Once all 15 of your checkers are in your home corner, you can take them off. Tap the checker, then tap the box on the right that says Off.

There is no timer and nothing to lose. Undo as many times as you like, even back past the computer's turn. Hint shows a move and tells you why it helps. There is no doubling and no extra points: you simply win or you don't.
