This is the Hungarian version of Crazy 8s, but it is played more like Uno. The difference is, unlike Uno, it is played with a deck of 52 cards. If there are a lot of players, two decks can even be shuffled together. There aren't really any "official" rules, which is part of what makes the game so much fun. It is an easy, laid back card game for two or more players, and now you can play Macao for Android whenever you want.
Each player gets 5 cards, and then one is left face up. Players have to discard a card onto the one that is face up by matching the number or the suit, each one playing off the last card discarded. You don't have to play even if you can as a way of psyching out other players. Just remember, anytime you do not play, whether by choice or because you have nothing to play, you must take another card from the deck.
This is bad, because the way you win is by getting rid of all your cards. The first one to get rid of all their cards wins, and the Swarm leaderboards keep up with the scoring so you can see where you stand along with other players. Can you make it to the top?
