Puzzle Master Space Rail Level 7

Object: Construct and operate your mini marble roller coaster. SpaceRail is a line of do-it-yourself marble roller coasters. Assemble the pieces by cutting track to the correct size, forming cubes, loops, runs, and drops, and attaching everything to metal rods in the plastic base. Once assembled, enjoy hours & hours of rolling metal ball entertainment.   The auger that lifts your ball back to the top will ensure that it is in constant motion, flying down the track to its next turn or looping through the track again and again.
This set is suitable for advanced users. An English instruction manual is included.
