In my attempt to make Doppel-Dög happen, now i ask everyone to make their own puzzles using it.
- Normal sudoku rules apply.
-
Doppel-Dög loop:
- Draw an orthogonal non-branching closed loop that doesn't cross or touch itself, not even diagonally.
- The loop "starts" at the cell marked with the dog and is considered to be oriented in the direction indicated by the arrow (i.e. r7c6 and r7c7 are in the loop).
- A cell on the loop with a digit D will have a value equal to the digit D steps away along the loop in the orientation given by the arrow.
- Cells not on the loop will have a value equal to the digit in them.
- Any three adjacent cells along the loop must have digits (not values) from all sets {123}, {456} and {789}.
- Values in a cage sum to the indicated total.
- Cells marked with a circle are not part of the loop and have a digit that equal to the count of the, up to 8, neighboring loop cells.
- Clues outside the grid show the value sum of loop cells in the indicated row/column.
Example: The numbers in red show the value of each cell. The dog cell takes its value from the cell 8 steps ahead along the loop.
Another Doppel-Dögs:
- can i pet that dog!?
- nopil nahual
- Convection Currents by ThePedallingPianist
- Doppel-Dög Sandwich by phil_the (hat)
- Tentropic Terrier by Scojo
- a changed man
Solution code: Values on column 8, top to bottom.

another great puzzle, mainly due to the break in and all the logic needed to get there. After that it goes from 5* difficulty down to maybe 3.5. Interesting how you end up using modular logic as well

more Dögs!

Another very impressive creation, and surely one of the most clever uses of Entropic Lines out there, or that I've seen anyway, with a key deduction that I wish I had been quicker to figure out, but I imagine that it’s this deduction that just outright stumped some of the other solvers.
For this reason, I actually found this one harder than ‘nopil’, but all that early work I did paid off, as ultimately, the holding CTRL-Y replay of my solve was only about 25 seconds, which speaks to the flow of the puzzle and is crazy for a variant this nuts. And what about that one [...] tho, and the very last disambiguation – hats off once again, really!

I love solving your puzzles, thank you very much for constructing and sharing them. This one was very fun

Playing with the rules of the low-middle-high set and the Value 4 cages gave me the start for the loop coulours/values. Very intresting rules and nice flow. Great puzzle - thanks.

Me the same. No break in found. I try to solve others of this kind first...

Well, I tried - but I'm going to have to wait until someone makes a video, ha ha. I got some loop cells and non-loop cells identified, but couldn't nail down a single digits. Clearly 4 or 5 stars.
