Nightmare is sadly right. While any and all new rules are worth initially looking into, ones that aren't actually fun to solve are usually worth discarding from a setter's toolbox.

This is just too much work for the solver; maybe limit it to only pairs which sum to five OR fifteen, not both at once? That would be less scanning work, while still keeping the ultimate conceit there.

--from riffclown. I'll fully acknowledge that this is a scan heavy constraint and it isn't for everyone. Like Anti-knight it will have both advocates and critics. Both are valid and welcome. I will point out that the CTC Knightmare Pack got really good reviews and even some reports of Knightmare being some individual's new favorite constraint.

---That's fair! Looking back, I think it could work just as well simply condensing the total to 10 rather than both 5 and 15 though. You're still looking for 4 pairs of digits that way (1&9, 2&8, 3&7 and 4&6), but only one total, rather than 4 pairs AND 2 totals (1&4 and 2&3 being 5, and 6&9 and 7&8 being 15). So would need just as much scanning (where every number except 5 needs to be scanned for) without adding a second layer of mental overload via a second total.

I still have to find my technique for this ruleset, but I'm happy I was able to scan and solve it!

I've really enjoyed solving this one, even though at first I couldn't find the break in. I had to get used to the knightmare rule and because of this solving took a full 30 minutes T^T

--This is indeed mostly a scanning exercise but it is intended to introduce the logic. The most common pitfall is trying to apply Anti-knight logic which isn't truly applicable in this variant.
