There are a couple of games that my team likes to play, a lot of them are dirived from drinking and party games but they gain an extra bit of fun and craziness if you add skates and ice to the mix. Two specific ones we love are "Wo ist mein Huhn?" (where's my chicken) and "Flunkyball" and the one I'd like to explain in more detail is the latter. Flunkyball is a mainstay in German youths drinking culture these days, two teams line up opposite each other with some distance between them, with each player having a bottle of beer (or any other drink, it can even be non-alcoholic in theory) in front of them. Between the teams is a water bottle or any other reasonably hard to hit object that can serve as a target. Now one team starts the game by throwing a ball (or shooting a puck for that matter) at the bottle. If they hit, they get to drink from their own individual bottles until the other teams has both retrieved the ball/puck and put the target back in its spot. The teams alternate taking shots no matter if they hit, and the first team where every player has finished their drink wins. There are some extra rules to add a little spice to the game as well: If you manage to hit the bottle in front of another player (which they are allowed to cover AFTER the ball has been throwin) instead of the main target or a player accidentally spills or knocks over his own bottle, he has to finish that one immediately and get a new one and start over. Let the fun begin!
