A lot of money in craps gets bet on odds that are close to even-money. It's hard, I think, to weight dice so that the house would increase their take by a measurable amount.

A lot of the effective value of a casino is gamblers ruin -- gamblers stop betting when they run out of money, but the house can't run out of money. If the game has sufficient variance and the players are not aware of the bias, then the house still wins.

It's for a reason similar to this that the only game I will play in casinos is craps.

It's not hard to imagine ways to get cheated out of a "fair" bet in card games, roulette, slots, etc. whether it's a mechanical cheat, sleight of hand, adjustment of odds, or whatever. Not saying it happens or is even a common occurrence but it's very easy to imagine ways it COULD happen or has happened in the past that are impossible for the player to detect.

Craps is the only game it feels like to me where provided the payout odds used are the same standard you see everywhere and the dice aren't metallic there is virtually no way to cheat the player/a bet in a way that wouldn't also benefit another player/another bet.
