Video Poker
Jacks or Better · Provably fair
Jacks or Better video poker. You're dealt five cards: tap the ones you want to keep (or press 1 to 5), then draw once to replace the rest. Your final hand is paid by the table above the cards, from a pair of jacks or better up to a royal flush.
The gold button deals the hand, then draws it. Hold what makes a pair of jacks or better, any three of a kind, four to a flush or a straight, and let the rest go. Held cards are kept, everything else is replaced from the same deck.
The whole deck is shuffled from your own provably fair seed pair when your bet goes in, and the page only learns the cards you draw once you draw. Check a hand on the Provably fair page. A hand left alone is drawn after ten minutes, keeping the cards you held.
