A game with thousands of rules ...?!

In circle 2 Card have the test of time: One is "6 takes" and the other United Nations. Both are highly recommended!
So actually the UN is nothing more than the well-known game all Mau Mau. Therefore, the explanation for new players, who do not know the game very quickly and easily.
Unlike Makao there are a few more tickets are numbered from 0-9 (there this is this all twice) and a few more action cards: color change, take 2, take 4 and color change, change of direction (instead of clockwise it goes counterclockwise on)!
With the rules easy to understand where you can quickly spend a few nice hours and even small children are fine with.
Before starting the game with unknown fellow players, however you should always check that they play their own version, which make the game more often funny and sometimes stressful:
Examples:
Playing the 0 all pass on the cards in play Richting
Who asks who it is or to take a long time to create a map, must take a penalty card.
Black on Black may (not) to put
Interposing: Since each card is duplicated, one must have identical card to the other card set (if you are fast enough). Then it continues with the player who has interposed. Otherwise: penalty card if you were too slow ...
On a +2 card (= 2 take) one must create a +2 card, take the next must be 4, unless he also has a +2 card (= 6nehmen) - This is really great (and messy) if you then also must interposing.
A card may +4 to + 2 card set (then take 6 ...
So there are really thousands of rules and make the game become a real experience. An ideal vacation game!
