Jugo Flower Puzzle

Game Jugo translates as Game 15 after the number of petals. It was manufactured by Kuroba (Clover) 1983 in Japan.

Due to its fragility only a small number were produced before production was stopped. It has been highly sought after by collectors ever since.

GROUP THEORY.

This is another puzzle requiring Group theory in its solution. The central cylinder can be rotated which repositions the little white arrows opposite 4 of the 15 petals. These 4 petals, and only these 4, can then be turned over.

After some random twiddling, restoration becomes a serious puzzle.

 

There were 2 finishes: The one illustrated here is "Cocktail", and "Papillion" is shown at the bottom of this page.
The six sides of the original box
The original instruction sheet
 

We are unsure who was the original inventor and we do not know who made this or the following prototypes.

 

Please tell us if you know as we would like to give them credit for these ingenious designs.

This is another very fragile prototype of a related puzzle in which the 3 numbers opposite the "hands" rotate when the winder is turned.
     
In 2011 Wil Strijbos has had made this all metal versions, to satisfy some serious puzzlers.

All 3 versions of Jugo.

With thanks to N.Takashima for help with the history of this puzzle.
