This work was designed for Karakuri Puzzle Party in Hakone 2018.
“Is it possible to make items of system such as Binary or Ternary with avery clear design?” I wondered about this so I decided to try and see if Icould do it. There are only 3 “drawers”. It is the minimum number that weneed to fully enjoy the system. There are only 2 devices. When you havesolved the puzzle, you can finally open the bottom drawer. The mechanismused for RF-38 “Canon Chest” was used.

This is a drawer of Quinary system. It takes 50 moves to open (exceptfor opening the lid). When all the 3 “drawers” are opened, you can open thebottom drawer. The number of moves has increased in this work. As might beexpected, it will take time to solve this item. The formula to calculate thenumber of moves is “5*5*2=50”. Well, how about the formulas of other items?
