I've come up with many variations to the Barcode Burr puzzle, most of which are more difficult than the original. I've color-coded the different sets to help distinguish them from one another:

• Barcode Burr (black inserts)
• GrayCode Burr (gray inserts)
• TernCode Burr (orange inserts)
• QuadCode Burr (yellow inserts)
• ExtremeTortureCode Burr (red/orange/white inserts)
• SuperCode Burr (red inserts)
• CoordiCode Burr (blue inserts)
• GreenCode Burr #1 (green inserts)
• GreenCode Burr #2 (green inserts)
• GreenCode Burr #3 (green inserts)
• GreenCode Burr #4 (green inserts)
• CrossCode Burr #1 (white inserts)
• CrossCode Burr #2 (white inserts)
• CrossCode Burr #3 (white inserts)
• CrossCode Burr #4 (white inserts)
• CrossCode Burr #5 (gold inserts)
• PurpleCode Burr (purple inserts)

This listing is for the insert kits only, so you'll need to get a Barcode Burr Body (corner piece) kit or scavenge a set from one of your other existing puzzles if you already have some.

If you are new to this family of puzzles and want to get enough parts to try everything, you might want to consider the Barcode Burr Master Set instead of buying individual insert kits a-la-carte here.
