This fun and challenging game for ages 7 to adult contains a set of building blocks and a number of multi-colored balls. To play the game, participants need to build a stairway of a desired size, place the balls on the stairs and flip the BiGA character to go down the stairs and gobble the balls. Who can get the most balls? Players can vary the number and position of balls per stair, and the game can be played at different multi-skill levels – from Beginner to Master, improving eye-hand coordination. The building set is extendable. Teachers and  scientists appreciate that more physics is incorporated into the game for teaching through fun action.
