During the game, you try to get rid of your alien cards as quickly as possible. In each round, you can play a maximum of 4 cards either vertically or horizontally. However, since not all aliens can be played together, you must keep a close eye on the action on the table. If you play cards in large groups, you receive a bonus that allows you to discard additional cards.

Why it's worth it:

1. Reiner Knizia, one of the most popular game designers
2. Simple rules
3. Solo mode available
4. The game develops observation skills, imagination, and competitive spirit.
