The Thales puzzle has a unique design, where the puzzle includes 4 layers with laser engraved numbers. The 'lower' layer (the larger bottom layer) doesn't rotate, however, the 3 layer on top of it can rotate.
The object of this puzzle is to turn/rotate the layers and stop them in a position where all the numbers lined up on all 4 layers (same row) sum to the same number.
There are 16 rows in all that each one of them need to have a combination of numbers matching to the other rows.
Now, let's see you figure out what is the number each row should sum to and how you make it happen.
Note: Wood color may vary.
