Like Blackjack, cards are chosen from a finite number of decks. So you can use the same chart to log cards dealt. Knowing cards already dealt gives you insight of cards left to be dealt. Be sure to read how many decks the machine you choose uses in order to make accurate decisions.
The hands you play in a game of poker in a table game isn’t necessarily the same hands you want to play on a machine. To maximize your profits, you should go after the more powerful hands much more often, even if it means missing out on a few small hands. In the long-run these sacrifices will pay for themselves.
Video Poker shares some strategy with slot machines as well. For one, you always want to play the maximum coins on each hand. When you finally do hit the jackpot it will payoff. Winning the jackpot with only half the max bet is surely to disappoint. If you are playing at a dollar machine and can’t afford to play the max, drop down to a quarter machine and max it out. On a dollar machine 75 cents isn’t the same thing as 75 cents on a quarter machine.
