Blob Giant 3D is a running game where you grow a jelly giant. Your hero runs along a track full of coloured jellies, and touching the ones that match your colour makes him bigger and bigger until the very end of the course.
Steer your runner into the jellies of the same colour and avoid the others. Each matching jelly adds to your size. At the end of the track there is a huge inflatable cushion. Jump onto it with all the energy you have collected. On the other side of the cushion, your teammates are launched into the air, and the more force you put into the jump, the further they fly towards the treasure chest waiting for them.
