So, if you throw in $2 on the initial bet toward the crap, the most you stand to win back is your $2 and $2 of the shooter's money. The other players must cumulatively come up with $10, but betting crap.
If you've anted up, you can throw in to match, or you can wait and bet on the side. To match the shooter's bet is to come up with the same amount of 'money,' in support of the opposite outcome. The other players must cumulatively come up with enough to at least match the shooter's bet before placing side bets or increasing the wager.The amount of the bet will be either 'pass' or 'crap,' though in some games it's assumed that the shooter will always bet on himself (or will always bet pass, in other words). Once the shooter is selected, the shooter will bet first.
