Proposition bets are those placed in the middle of the table layout. Those bets never have a good house edge. You should make these bets only for fun and to make your game more exciting.
Any Craps
The house edge for this bet is 11.11%. When making this bet you bet that the next roll will be a 2, 3 or 12 also known as craps.
Any Seven
With the "any seven" bet you're betting the shooter will hit a 7 on the next roll. It pays 4 to 1 and has a house edge of 16.67%
Eleven or Three
Actually those are two separate bets. With the first one you are betting that the next roll will be an 11. with the second one you are betting that the next roll will be a 3. Bouth of them pays 15:1 with a house edge of 11.11%.
Twelve or Two
Again two separate one-roll bets, one that the next will be 12, one that the next will be 2 and this one is also known as the snake eye bet. It pays 30 to 1 and has a house edge of 13.89. As all the other proposition bets, don't even thing about it.
Horn Bet
If any one of the numbers: 2, 3, 11, or 12 is rolled, you win. If any other number is rolled, you lose. You have to place one unit on each number. If a winner appears the bet is paid at the posed odds of the individual number. The house edge for this bet is around 12.50%.
Horn High Bet
This bet is the same as a horn bet but putting an extra unit on the 'high' number of your choice. The house edge depends on what number you choose to be high, but it's always humongous.
C & E
This is a one roll bet that the next number will be 2, 3, 11, or 12. 2, 3, 12 is craps, so the name is simply saying Craps and Eleven. This bet is cool because you get to use those neat little circles. Oh and the house edge is well into the double digits, so if you actually bet on it, you're so very uncool.
Hop Bet
The hop bet is a one roll bet that the next roll will result in a particular combination of the dice. So the image of a combination of dice is put right on the felt, how friendly. What's unfriendly is the 13.89% house edge on the 30 to 1 bets, and the 11.11% edge on 15 to 1 bets.
