I wrote a review of Flaschenteufel. It’s in Finnish, as usual.
To sum it up: I gave Flaschenteufel five stars out of five. I think it’s one of the very best card games around. It’s good for gamers and non-gamers — both groups will probably enjoy the strong and exciting theme. Gamers will appreciate the tension you feel when you have the bottle and some small cards in your hand and the deal is moving towards the end and you’d have to get rid of the small cards and the bottle and if you fail, your hard-earned points will be lost and… It’s just great, really.
