This game is mostly for the little ones, from 6 years old. Maximum weight is 50 kg. One can use it for 5 minutes, assisted by an animator. The balls are attached to buoys, which are located at maximum 20 meters from the bank. Usually there is no water inside the ball, but a few drops might enter, so guests should use their swimsuits when playing this game. The use of the ball is highly not recommended for claustrophobics and for people suffering from heart diseases and panic disorder!
