Logic Masters Deutschland e.V.

I was inspired by the isofill ruleset of Marty Sears

Rules:
ISOFILL: Divide the grid into 10 regions, each with 10 orthogonally connected cells. Every cell in a region should contain the same digit. All of the digits 0-9 must appear in the grid.

REGION ROTATION PAIRS: The ten regions are divided in 5 pairs. Two regions form a pair when their unique digits sum to 9. Two regions that form a pair have the same shape rotated by 180 degrees.

RENBAN LINE (purple): contains a set of consecutive digits in any order, without repeats.

SLOW THERMOMETER (grey): Numbers increase or stay the same as they move away from the bulb.
