Dragon Ball is a Challenge Puzzle where players must solve 8 challenges to complete the trigger requirement. It is re playable, because every time they play is different. Players roll a steel ball "uphill" along two aluminum rods, defying gravity to reach the targets. 
This game arrives in two parts; top cabinet and lower cabinet. It is easy to assemble and will fit through a standard doorway. Just hook up your own trigger result; a door lock, maglock, lighting etc...
