If you like playing poker then you may think that there is no substitute for the real thing. However, you may be one of the people who enjoys poker slots and would not consider playing the card game. As with many things it is a matter of taste and you may find that you like just one version of the game or that you like both.
If you have had experience of either game and have enjoyed it, then it could be a good idea to try the other and see what you think. You may find that you like them both or prefer one over the other. You may realise that the other game is quite different to how you imagined.
Playing the card game of poker is very tactical. It can be interesting as no game is the same and how well you do can partly be determined by how good the people you are playing against are as well as the cards that you are all dealt. There are lots of different versions of the game but you will tend to bet on yourself having the best hand. Poker slots are different in that you do not play against anyone. You just look at the hand you are given and decide whether you would like to keep any of the cards, then you change the ones you do not want to keep and see whether you can get a hand which scores. How much is paid out and what each hand will win, depends on the specific game you play. It is very much simpler than playing poker with cards and therefore can be more relaxing. You also can play by yourself and may rather do that.
Of course, you may like to have a go at both. You may enjoy the deep thought and tactics that go in to the card game as well as the fun you can have relaxing when you are playing the slots game. They are very different but can still be enjoyed by the same people.
