FUBI is "eines der bester Tischfussballbillardspiele der Welt" - One of the best table football games in the world. It made the Games 100 for 2002 where they said "It's more challenging than regular soccer (or billiards) and a hoot to boot!"
Basically, It's a football pitch with pegs hammered into it. There is an elastic band surrounding the board. On your turn, you smack a heavy metal pinball and try to get it into the goal. If you fail, your opponent hits the ball from where it stopped. Keep going until someone scores!
