First, here is a table of the roll possibilities and point values:

The rules are simple. Two to four players may compete. The first player to reach 100 points or more is the winner. When it is your turn, you roll. If you get a Pig-Out or an Oinker, then you pass the pigs onto the next player. If you get anything else, you may decide to roll again or pass the pigs. If you keep rolling again, you accumulate points to add to your bank but if you get a Pig-Out, then all your points accumulated this turn are nullified.
