Normal killer cage rules apply: digits in cages cannot repeat and must sum to the number shown in the upper left corner of the cage.
Every diagonal of length 7, 8, or 9 is either modular or unimodular. On modular lines, every set of three sequential digits contains one digit from {147}, one from {258}, and one from {369}. On unimodular lines, all digits are from the same class (all from {147} or all from {258} or all from {369}).
