11.265% HA. Stupid game.
Quite simply, there are 33 outcomes. A tie happens 11.26% of the time, which is the advantage.
What a sucker game it is!
It seems like a game for people who are afraid to learn craps,
or just prefer an uncomplicated dice game with simplified payout and zero math.
Take a 7, which is the outcome 16.67% of the time. You have 15 ways each to win and lose, and 6 ways to tie. The tie rate is 16.67%.
For 6 and 8, the tie rate is 13.89%
For 5 and 9, the tie rate is 11.11%
For 4 and 10, the tie rate is 8.33%
For 3 and 11, the tie rate is 5.56%
For 2 and 12, the tie rate is 2.78%
Really, the HA is (6/36)^2 + 2*(5/36)^2 + 2*(4/36)^2 + 2*(3/36)^2 + 2*(2/36)^2 + 2*(1/36)^2.
= (36 + 50 + 32 + 18 + 8 + 2)/1296 = 146/1296 = 11.2654%
Game is called Beat the Dealer. Very simply the dealer rolls two die in a box (Sic Bo style), setting the point. The player then rolls the two die craps style, and if the player's roll beats the dealers roll, all bets are paid even money. Ties go to the dealer. Game has a very high house edge, but has been extremely popular so far. The table is a craps box with a different felt, and every time I have been to this casino the table was been very full. Minimum bet is $1, max is $100.
In VERY new gaming markets, just about any Chevy Chase type games can get installed and get action.
I realize that bad a house edge would make them redundant, but it's the "big money" bets that keeps the suckers betting.
My HA is correct.
Yes it is. If the dealer rolls the 12 it is an auto loser, but your edge is correct because even if they player were to get a chance to roll, a 12 would still be a tie, which is a loss.
