Cross the Tubes has now been out for a week. It’s proven to be pretty difficult, so hopefully the interactive version and hint below will be useful.
Once you’ve finished that, you can try out this week’s new puzzle, Chain-Link Crossing. This is the final feeder puzzle before next week’s metapuzzle.
Rotate the tubes to create a single linked system with no tubes ending at gray lines. You may play an interactive version of the puzzle here. Once you have finished this step, focus on the white squares.
