We invite you to exciting races and you will never guess who will compete: motorcycle racers, cyclists, race cars or just runners. At the start, the usual seemingly multi-colored balls of them will appear blue - yours, for which you will be responsible and how you will manage. As soon as the start is given, roll along the winding track, which, like a tape, bends and tends forward. Your ball can not only roll, but also run. Because he will have legs as soon as necessary, and if he accelerates very much, he can take off and then go down smoothly, opening a small parachute in Rolly Legs.
