The game is a variation of Pig. Here is how the game works:
There are about 20 players. Each round, a single six sided die is rolled. All players add that rolled number to their "bank." However, if a 2 is rolled starting at the 3rd round, all banks are set back to 0. Before a die is rolled, a player can choose to sit down and add their bank to their score, keeping it permanently. The game is played until scores are reset a total of 6 times, at which point the player with the highest score wins.
What is the best time to sit down each round to have the highest chance of getting the greatest score?
