For me, there's nothing better than Poker if we're talking about skills games, but there are other options. There's also blackjack and, I'm quite surprised no one mentioned Spades, it also includes a lot of strategic thinking, no less than Poker, perhaps. And, of course, there's Yahtzee. While it includes dice, which brings an element of luck to the game - a strategy should also be applied and you need to make a lot of decisions, evaluate your risks, which is why to play this game it's better to understand probabilities first.
