I have gotten quite hooked on these Tessellation puzzles that juggler and others have been setting. After solving or seeing a couple of gdc's Mad Fold-In puzzles, I just had to try to combine the two variants. I hope you enjoy!
Rules
TESSELLATION
- Fill each cell with a digit from 1-9.
- Cells sharing an edge can't have the same digit.
- Each horizontal row and vertical column contains a non-repeating consecutive set of digits (like 23456) in any order.
DUTCH WHISPER LINES
- Adjacent digits along an orange line must have a difference of at least 4.
FOLD-IN
- Dashed red lines are folded into each other so that columns 1-4 and 7-9 form a smaller 7x7 Tessellation grid.
- Tessellation AND Dutch Whisper rules still apply after the grid has been folded in:
*** Rows must still contain non-repeating consecutive sets of digits in any order.
*** Cells sharing an edge can't have the same digit.
*** Adjacent digits on an orange line must have a difference of at least 4.

Very clever. Halfway through I got stuck and I had an intuition of what the correct path would be, yet couldn’t prove it til I slept on it. Love the combination of rules thanks :)
MSDOS: Thanks so much Spider! There are a couple of steps in the mid-late solve that are potentially 3.5-4 star. The combo of the tessellation and fold-in make for some very unintuitive cell-adjacencies.

Really cool to see folks setting these! The fold-in idea works surprisingly well, and I liked the break-in. Though I got a bit stuck on the second half of the solve.
MSDOS: Thanks for coming up with the grid type and creating the space for so much creativity!
