The rules are simply explained:


Each player gets three cards. The goal is it to have as many points in his hand as possible. For cards with the same color, the points add up. Aces give 11 points. Face cards 10. Otherwise, the number of the cards count. Alternatively, you can collect cards of the same rank. However, there are only points(30.5) if all three cards are of the same rank. You can either exchange (by tapping the cards) one card or all cards. Alternatively, you can push too. The first player can in the first round only push or exchange all cards with the middle. The game is over when one player has 31 Points or the player is turn back who has knocked. When a player loses and has no more life, he is eliminated. The last one left wins the game.
More detailed rules are easily to find on the web.

Way better than the "Schwimmen Deluxe" App, but still you game makers don't understand the fact that "changing the rules to those I'm used to play with" doesn't mean to give me three or four options to change but necessary changes can't be made. Also I got no clue why every game ends after two rounds...

Thanks for your review. Usually, a round of a game end after few rounds, because the round end if a player has 31 or more points or he had knocked in the round before. If you miss a rule option, please let me know and I will develop an Update.

I don't like that you can't login to anything like Facebook or Google. So the progress doesn't get saved if you uninstall for whatever reason.

I'm sorry the game doesn't meet your expectations. After my extensive testing, the incorrect counting shouldn't be happen. Can you please send me an example screenshot to contact@hensch-it.de so I can take a look at it? If you have any further suggestions for improvement, I would be happy to include them in a future update.
