I forgot about the knights move constraint and was able to get most of the way through (more complex). Wish there were a different way to disambiguate the renbans without knights moves :)

Great use of the anti-knight rule! Thanks for sharing.

On an different note: man, those 3 on the corner. What did Simon do? It became to a point where if there's a pair on the corner and one of them is 3, well, it's almost a new rule already hehehe

"Mom, can we have 1* sudoku?"

this was brutally hard ... then i checked the rules ... lol, no, that didn't happen today.

but seriously, this DID feel harder than level 1 ... then i used FOCUS ... all you need is basic sudoku and basic addition ... at all steps, there's at least ONE EASY STEP.

Beautiful puzzle, but definitely a low 2* for some tricky spots.

I didn't notice the humor of the given 2's till after I finished. It does take two. And a Two star puzzle for me. And just like real life, while it does yield fun results, the puzzle was more difficult than one might imagine.

Fun but definitely more than a 1*

For some reason I really struggled with this one. Glad I persisted though. Thank you for a lovely construction.
