Buchclub edition, marked SPIELE CLUB EXCLUSIV
Actually, it is a compilation, because Check Point (34449) is inside, too. (But not mentioned on the box)
Compared to the Schmidt version, there are the following differences:
Pads only in black and white, no color.
Evaluation sheet (Bewertungsbogen) has half the size.
Sheets tasks and solutions are doublesided, so 2 instead of 4 card boards.
12 instead of 36 Joker cards.
1 instead of 2 sand timers
