Game of PIG - Sixes

PIG - Sixes is a game for two players, played with two dice.

The winner is the first player to accumulate 100 or more points. Players all start with zero points, they take turns and they can throw the dice as many times as they like, adding the total at each throw to their cumulative total.

• Throwing one 6 ends the turn and nothing is added to the score for that turn. 
• Throwing a double 6 ends the turn and sets the total score back to zero. 

Try playing against Piggy. Can you work out Piggy's strategy?

Can you find a better one?

Imagine we change the rules of the game. How would your strategy be affected?

• A one-die version: Roll just one die. If you roll a six, your turn ends and your total reverts to what it was at the start of your turn.
• A friendlier version: double sixes don't reset your total score to zero, but one or two sixes still ends your turn.
• Game of PIG - Ones: If you roll a one, your turn ends, if you roll a double one, your total score is reset to zero. Sixes are safe.
