Pop-One Marble Race marble run - 108 parts to build yourself

Description

The box reads 'Pop-One Marble Race' with '108 PCS' next to it. It is a marble run in loose parts: straight and curved tube sections, funnels, dishes and supports in bright colours, plus the marbles that roll through them.

Building is half the game. Stack the pieces, let a marble go, see where it gets stuck, adjust the track and try again. The box shows four example layouts; anyone who would rather invent their own can simply ignore them.

The box states explicitly that colours and contents may differ from the illustrations. The packaging measures 65.5 × 45.5 × 12 cm and weighs 2.76 kg - a sizeable box to put under the Christmas tree.

A present that is not finished after one go: the track looks different every time, and rebuilding it is as much the game as the marbles are. A flat floor or a low table works best, because a tall track needs room.
