Jacks or Better Simple Strategy

Last update: Sep 24, 2001

The following strategy is my "simple strategy" for jacks or better video poker. Using the strategy on a full pay machine will result in an expected return of 99.46%. Compared to the optimal strategy return of 99.54%, mistakes in the simple strategy will cost 0.08%, or one total bet every 1178 hands.

To use the strategy look up all viable ways to play an initial hand on the following list and elect that which is highest on the list. A "high card" means a jack or higher.

Four of a kind, straight flush, royal flush
4 to a royal flush
Three of a kind, straight, flush, full house
4 to a straight flush
Two pair
High pair
3 to a royal flush
4 to a flush
Low pair
4 to an outside straight
2 suited high cards
3 to a straight flush
2 unsuited high cards (if more than 2 then pick the lowest 2)
Suited 10/J, 10/Q, or 10/K
One high card
Discard everything

Terms:

High card: A jack, queen, king, or ace. These cards are retained more often because if paired up they return the original bet.

Outside straight: An open ended straight that can be completed at either end, such as the cards 7,8,9,10.

Inside straight: A straight with a missing inside card, such as the cards 6,7,9,10. In addition A,2,3,4 and J,Q,K,A also count as inside straights because they are at an extreme end.

Example: Suppose you have the following hand.

The top three plays are (1) keep the low pair, (2) keep the 4 to a flush, and (3) keep the 2 suited high cards. The 4 to a flush is listed highest and is thus the best play, so discard the 3 of hearts.

Comparison to Optimal Strategy

The following table compares the probability and return of each hand under both the simple strategy and the optimal strategy.
