A full-size one is generally about four foot long and two foot wide. A standard table has eight rows of playing figures fixed to horizontal metal poles.
Each player controls four rows of these figures. The poles are pushed and twisted, and in this way the players can move the foosball-players around, pass the ball between the players and shoot at the goal.
A large number of different designs exist. Some are very simple and budget priced. Some are very elaborate and sleek. Some companies have manufactured very luxurious tables available for players to buy for their homes. You will often find a pay foosball table in a club or bar.
