The sharpshooting is extremely difficult. It takes a long time to get right. No idea what sort of advantage you can get on it, but I've heard of some guys making alot.

Roulette, well most roulette advantage players let a palm computer do the work for them :wink: Variance isn't as high as you'd think. For an advantage player the risk is in getting caught, not losing their BR.

Video Poker is the easiest advantage play out there. Alot of variance, so you need a large bankroll (in relation to bet size). You basically find a machine where the pot is high, and you play VP basic strategy.

Blackjack (card counting). What you do is keep track of the cards that have come out, so then you have an idea of cards still to come. You see the more high cards left in the deck, the better for the player. More high cards= greater chance of dealer bust, greater chance of BJs, and better results of doubling and splitting.

There is plenty of info around the net on card counting.
