shoot to win craps

i saw this at Treasure Island yesterday. apparently its now at the redrock too. its an electronic craps game where you bounce the dice inside this cylinder. what i found interesting is the $1 wagers. they round up instead of rounding down. so a $1 placebet on 6/8 pays $1.17 ($1.1667) and a $1 buybet on a 5/9 pays $1.43 ($1.4250). also commission on buybets are paid on wins only.
