I have the game for the first time to play in a 5-man round on weekends. The rules are added somewhat complicated (too many things at the same time), but no later than the 3rd cycle one gets the hang of it. The fun factor is inevitable, since one of his own recurring error - and that of others and - can laugh heartily. The hustle and bustle of the cards reveal was very amusing.
The game promotes concentration and logical thinking and is therefore suitable for young and old. The age I find a bit too low, but that's just a personal opinion.
