Normal sudoku rules apply. Digits in a cage sum to the number shown. Adjacent digits on a green line differ by at least 5. A pink line contains a consecutive group of digits in any order without repeats. Each digit 9 must not be a chess knight’s move away from another 9. Each digit 1 must be a chess knights move away from at least TWO different 1s. All knight’s moves see the grid cylindrically/as a torus, for example R1C2 would see R2C9, R8C1, R8C3, and R9C4 wrapping around the grid; as well as normal knight’s moves like R2C4
