# https://www.amazon.com/Puzzle-Day-Acrylic-Original-Challenges/dp/B0BNRSLTG5?th=1 The acrylic version of the puzzle has colors for the pieces. Perhaps change our colors to match? Techincally you can reach all possible orientations & flips of a piece in just three bytes (instead of four). A flip horizontally & vertically is identical to a 180 degree rotation, for example. You can probably get away with just a horizontal flip and then 0,90,180,270 for a total of three bytes.
