After making several puzzles with twin grids, I wanted to try and make something with 3 identical grids. Here is an experiment I made with killer cages. This was trickier to set than I thought, probably because of the nature of my ruleset. Have fun solving !
I found that having the 3 grids side by side was easier for scanning between grids, but if you wish to optimize screen space, you may want to use one of the links below instead.
Rules :
Normal sudoku rules apply in the 3 grids (with digits 1 to 6)
The cells that are in the same position in the 3 grids must contain 3 different digits. (For example, R1C1 cells may contain 2-3-5 but not 2-3-2)
Killer cage : Digits can not repeat in a cage and sum to the total in the top left corner, if given. If the total is not given, it still has to be the same for the 3 cages that are in the same position in the 3 grids.
The cages that are in the same position in the 3 grids may not have the exact same composition of digits (For example, a 3-cell 12 cage could not be 3-4-5 in 2 different grids)
R6C4 (marked by an hexagon) has the same parity in the 3 grids.
Solution code: Column 5 of the grid with the lowest digit in R1C5, followed by column 6 of the grid with the highest digit in R1C6

This has all the hallmarks of a puzzle that seems approachable enough on the surface but will have taken painstaking hours to set that way. Thank you for all your hard work, this was a beauty.

Seemed like a nightmarish idea from the outset, but had some great smoothness and taught me a few things about 6x6 killer math! Scanning got a bit tricky towards the endgame, but there was always a clear point to be found.

Very cool, thanks!
