Puzzle Generation

Puzzle generation technique was taken from this great Stack Exchange answer

Puzzle "seeds" are generated from here.

A series of transformations is then applied to a seed

  1. Remap tokens, for example mapping all 1s to 9s and 9s to 1s still gives us a solvable puzzle (~300,000 variations)
  2. Rotate the puzzle by 0, 90, 180 or 270 degrees (4 variations)
  3. Reflect the puzzle vertically, horizontally, both or neither (4 variations)

This way one seed can be used to create ~4,800,000 different puzzles
