'Black Rainbow Tower' Puzzle Box

A limited edition - 1 of 20 - sequential-discovery puzzle box/marble maze.

Made to order by me, BRT is a tricky puzzle and marble maze all in one.
Drop the brass ball into the top of the tower then figure out how to get it to come out on the ground floor. There are at least a dozen moves/hidden moving parts/tools to discover along the way.

This design is limited to 20 boxes. Further varieties (colour changes/architectural changes) may be created in future depending on demand.

This puzzle is designed for adults; there are a number of small parts. Not suitable for young children.

Although I will try to respond and get your puzzle box out in a week or so, they are painstakingly put together and at times may take longer to produce.
Please bear this in mind when ordering.

* Designing puzzle boxes is a new interest for me – look out for further designs to appear over the coming months.

This puzzle box is made entirely from new elements and ships assembled, ready to solve. All puzzles are personally assembled, tested and reset by Christophe Gowans, the designer. Solving and reset instructions (PDF) will be emailed at time of shipping. No refunds. I am not responsible for packages once shipped. None of my products are endorsed by or affiliated with The LEGO® Group. Not suitable for young children - small pieces present a choking hazard.
