In this game, players make sets of not-matching cards.
Four cards are placed on the table. The rest of the cards are distributed between the players.
The cards are double-sided. Each side is either blue, green, or orange, and shows one, two or three objects (astronauts, moons, and rockets).
Everybody will simultaneously try to make (and then complete) sets of cards. To make a set of two cards, they have to have different objects, different numbers of objects, and different background colours. To complete the set, the third card has to be added (being different from both other cards in all aspects). Once you've completed a set, you collect it as a trick and get to play a new card to the table.
The game ends when someone plays their last card, or when no more plays can be made. The player with the most tricks wins.
