We play the game since tens of years at home. I took it in recent times also at different circles of friends, anywhere it comes to super. Power just mega mood. On the subject of luck or skill: A bit of luck is always of course to that is quite normal in games. But most of all it depends on skilful weigh their own card. You learn over time. 2 players would be too boring. Also at 3 happens relatively little, but is entirely possible. The most fun is it with 4-5 players. With 6+ players it's a "murder Gaudi", but is increasingly becoming a matter of luck.
Tip: So we play it: After each round, we write on a great summary sheet for the negatives of all players. If the first player has minus 100 points, the game is over.
