Wooden Roller Puzzles
The roller puzzle is designed by Rokus and Corry in 1979. Puzzle pieces can be put on wheels with notches which suddenly give new dimensions of play. The puzzles are designed and produced for Simplex, the puzzle manufacturer which had tight connection to Sio.
The puzzles have drawings of traffic with trains, cars, traffic signs and farms with animals and equipment.
The puzzles are an immediate success and have been produced in large numbers.
At the annual press day of the Royal Dutch Jaarbeurs in Utrecht in 1980, the Roller Puzzle was awarded by representatives of the national and international press.
Many designs made by Rokus and Corry have been copied during the years. After the presentation of a design, the next year the copies appeared in stands from countries like the DDR, Greece or Taiwan.
This happened with the roller puzzle. Copies of the puzzles appeared already in the first Toy Fair in Nuremberg the year after the introduction.
Corry hid her initials CVBM in her designs. The puzzle with the farm and tractor was copied with letters and all, including the CVBM on the hood of the tractor.
