Pig is a simple dice game first described in print in John Scarne in
1945. Players take turns to roll a single dice as many times as they
wish, adding all roll results to a running total, but losing their
gained score for the turn if they roll a 1. Each turn, a player
repeatedly rolls a die until either a 1 is rolled or the player decides
to "hold": If the player rolls a 1, they score nothing and it becomes
the next player's turn. If the player rolls any other number, it is
added to their turn total and the player's turn continues. If a player
chooses to "hold", their turn total is added to their score, and it
becomes the next player's turn. The first player to score 100 or more
points wins.
