Anti-Knight 4's- Every 4 in the puzzle cannot be a chess-knight's move away from each other

Row 6 Indexers - Every digit in Row 6 indicates the placement of that cell's row number in its column (ie if R6C8 is a 4 then R4C8 is a 6)

Column 1 Indexers - Every digit in Column 1 indicates the placement of that cell's column number in that row (ie if R4C1 is a 7 then R4C7 is a 1)

Black Renban line - must be a set of consecutive non-repeating digits

Red Killer Cages - digits must add up to the total in the top left hand corner. Digits may not repeat in a cage
