The solution to Cross-Breeding, the puzzle from two weeks ago, has now been posted. The hint for last week’s Cross the Tubes is available as well.
The final regular puzzle for this set is Chain-Link Crossing. Come back next week for the May-June metapuzzle. As this puzzle was originally borderline impossible, it has been updated as of 5pm CDT on 22 June. You have my sincere apologies.
