Normal Sudoku rules apply.

The grid "wraps around" (the top connects to the bottom, and the left edge to the right edge).

DUTCH CELLMATES: Every digit in the grid needs to have a digit at least 4 greater in the cell below it, or a digit at least 4 smaller in the cell above it. It may have both, but doesn't need both.

CAGES: Cages chained to each other have the same sum.

Solution code: Row 1

Pretty interesting puzzle, this ruleset has some clever implications that was nice to figure out.

Everything I look for in a puzzle - Michael Lefkowitz, Dutch Flat Mates, rated 2 Star difficulty. I Couldn't get my head around solving it, glad I saw olliwright in the solvers list so went on Twitch to find and watch the video of him solving it.

Fun! At the beginning it seems like there can't possibly be enough constraints, but then things piece together and I see the structure.

Fun idea. A little time to work out the implications of the ruleset then smooth from there. Thanks!

Very nice puzzle. It is amazing how this resolves with only a few cages.
