Another unique design and this one has two puzzles in one. The object of both puzzles is to turn the 6 hardwood wheels such that all columns add to 100 at the same time.
There is a SUPER difficult side with 12 columns of numbers. There are over 248,000 possible permutations with 1 possible solution. A hard level 5 puzzle.
The flip side has 6 columns of numbers. It is still quite challenging (level 4) with over 7700 permutations with only 1 possible solution.
The numbers are all deeply laser engraved into the puzzle. Woods used are rubberwood, maple, or ash (all light colored wood that lasers well) depending on what was available. This is a beautiful puzzle that displays well.
