You find the machine you like, choose to play for free or real money, place your bet and click/tap the “deal” or “draw” button. The computer will deal you five cards. From there, your goal is to make the best possible poker hand (by holding and/or discarding cards in your hand) based on standard poker hand ranking rules. Typically, a pair of Jacks - or a pair of other face cards (queen or king) or aces - is the lowest possible payout.
