Street football games are usually individual based, as it's not really suited for team games. Street Football games ALWAYS result in the loser receiving "Batty Beats" AKA "Tan Arse".
Batty Beats is where the loser has to stand on the goal line and bend over and present their arse for the rest to kick the ball at. The distance from which you kick is down tou the group playing. I personally play minimum one step(It's a bit shit when everyone takes it from halfway and misses).
Here are some examples:
Heads and Volleys: Self-explanatory. You can only score with a head and volley. Volley's will have to be from a certain distance, usually outside the box if there is one.
Shooting game: This is a tan-arse-fest. Self-explanatory, shoot from behind a certain distance. Goalie loses all his lives = Tan arse.
For both of the above games, the goalie changes when the ball is caught, or kicked wide or over. Certain variations may allow you to kick it over or wide etc if the "Over saves all" rule is in play, or "Post saves all" etc.
Here is one that a friend of mine made up after he got a nasty injury which prevented him from playing to 100%.
The post game: This is more calm game. It's all about accuracy. You simply have to hit each post; Left, right, crossbar, and middle. For the middle one the football cage has to have another post running down just behind the goal, down the middle, this is extremely hard to hit. Once you have hit each post you are through. Last person through receives batty beats.
What variations do you play?
