Video Poker
Video Pokers usually have the lowest house edge of all the games, however they have extremely high variances due to their sliding pay tables. The high return on the least likely hands help casinos boost the player odds. However until you get those hands the house edge is quite high.

To boost play through speeds and to lower the variance, use 50-play versions if they have the same pay tables. Just beware that these versions may not count toward wager requirements, also there may be a minimum wager amount to recieve jackpots or the highest payouts.
