PIG

In each turn, a player repeatedly rolls a dice until either a 1 is shown or the player decides to "hold".

If the player rolls a 1, he scores zero and the turn goes to the next player.

If the player rolls any other number, he scores the total and he continues its turn.

If a player choose to "hold", he scores the total and the turn goes to the next player.

The first player to score 100 or more points wins.

This is a version with two players: you and your device which follows an special strategy.

The app can be used as a personal trainer to play after with your friends on a table with actual dices.
