If you want to play Jacks or Better always keep this tips in your mind:
Jacks or Better Video Poker (the 9/6 Version)
Make sure you’re playing a full-pay 9/6 version by looking at the Full House/Flush payouts forone coin.
Because of the increased payouts for a royal flush, always play the maximum coins to get the best odds even if that means finding nickel or quarter machines to stay within your bankroll.
Never keep a kicker (a high card along with a pair).
Throw away a small pair (tens or lower) if you have four cards to a flush or three cards to a royal flush.
