White Kropki dots: Digits separated by a white dot must be consecutive.

Killer cages: Digits in a cage must sum to the number written in the top-left corner of the cage.

Odd/even digits: Digit in a not-fully-shaded cell with a shaded square must be even and the digit in a cell with a shaded circle must be odd.
