This is a game is great for a party with your best friends or if you go out in the evening with them.
The goal of the game is to always tap the grey square. After each tap the square changes its size and position randomly. If you are lucky, the square rests big, otherwise you probably miss it and the Prosit!-Circle appears. At this point you have to drink something of your choice. After every tap, its the turn of the player next to your right. If the square is to small and you miss it five times, it resets to standard size.
