instruction: per this description of the game of fooseball, how many full rotations are allowed in the game at the championship level?
output: 2 360-degree rotations are allowed since January 2012.
input: The game involves using figures mounted on rotating bars to kick a ball into the opposing goal. Table football tables can vary in size, but a typical table is about 120 centimetres (3.9 ft) long and 61 centimetres (2.00 ft) wide. The table usually contains eight rows of foos men, which are plastic, metal, wooden, or sometimes carbon-fibre figures mounted on horizontal metal bars. Each team of one or two human players controls four rows of foos men, one row each for the goalkeeper, defenders, midfield and strikers. Players manipulate the rods to control the figures, using them to hold up, pass or 'kick' the ball. Games begin when the ball is served through a hole at the side of the table, or simply placed by hand at the feet of a figure in the centre of the table. A coin toss is usually used to determine which player or team serves first. If it is not the first match or if the ball gets out of play or if the ball suddenly stops out, then the team scored last would get the serve after he scores one. The term for when the ball leaves the table or gets stopped somewhere out of the men-like figures’ reach is dead ball. Expert players have been known to move balls at speeds up to 56 km/h (35 mph) in competition.
  
  The rules prohibit "over 360-degree shots", or "spinning": using the palm of the hand to swiftly spin the bar all around, instead of using wrist strokes to kick the ball with a bar-mounted figure. Since the establishment of the International Table Soccer Federation (ITSF), the rules have become standardised in most international competitions. However, since January 2012, the annual World Championships and the World Cup have permitted two full 360-degree rotations.
  
  The winner is determined when one team scores a predetermined number of goals, typically five, ten or eleven in competition. When playing Bonzini competitions, the target number of goals is seven and players must win by at least two clear goals.
