How to play PigDice

1. Each players has 2 dices.
2. Each player rolls the 2 dices and sums up the sum of both to their score.
3. However, if one dice gets 1, overall score is set to 0 and it's the next player's turn.
4. The player can choose to play or hold (hold = give the turn to the next player)
