Jacks or Better is a video poker game, found in Las Vegas casinos and also online. Like all video poker games, the player makes a bet and receives five cards, each of which can be retained or discarded for a new one. The resulting hand is evaluated, and credits are awarded for winning hands. The bet can be from 1 to 5 coins or credits. The payoffs are 1 for a pair of jacks or better, 2 for two pair, 3 for three of a kind, 4 for a straight, 6 for a flush, 9 for a full house, 25 for four of a kind, 50 for a straight flush and 800 for a royal flush.

There is an optimal strategy for playing Jacks or Better, and when used, the game will pay off, in the long run, $99.54 for every $100 wagered.
