Good card games can be so simple: either take a card or pay a chip. Anyone can make that decision, right? However, there's a catch - in fact there are two. Nobody wants the cards, not even for free, because they give you points in a game where you need to have the fewest points to win. And the chips? They are scarce, very scarce.
An excellent filler game that appeals to non-gamers as well.
3-5 players. 20 minutes playing time.
