Field Bet (craps)
A one roll wager that the next number will be a 2, 3, 4, 9,
10, 11, or 12. If a 3,4,9,10,or 11 is rolled, you win even money.
If a 2 or 12 is rolled, you're paid 2:1. Some casinos pay 3:1
for either the 2 or 12 (but not both), and some casinos may
make the 5 instead of the 9 a field roll. This is a one roll
bet that can be made anytime.
