Black Kropki Dots: Cells joined by a black dot must have a 1:2 ratio.

Polarity Line: Every pair of consecutive cells along a red polarity line must contain a low (1,2,3,4) and high (6,7,8,9) digit.

Shade cells in the 7x7 window. No shaded cell is orthogonally next to each other. A straight (orthogonal) line of unshaded cells cannot pass through more than two regions (only crosses one or zero region lines). Cages tell exactly how many shaded cells are in the enclosed area. (Cages do not count as extra regions)
[Despite being similar to heyawake, unshaded cells do not all have to be orthogonally connected to eachother.]

The digit on a shaded cell is higher than or the same as any diagonally adjacent shaded cells below it. If the shaded cells has no shaded cells below it, then the digit will be 1.
