Logic Masters Deutschland e.V.

No trial and error is needed to solve, but this does include some very challenging logic.(Who wrote this line, I don't care, I'm going to abuse it. It's just so funny to read this line.)

Standard sudoku rules applies. Fill the grid with numbers from 1 to 6 so each digit occurs exactly once in every row, column and 2x3 box.

Clues outside shows the difference between the first digit X and the x-th digit.

And here we go.

It's not laziness. It's coincidence.

This one is a little hard, so I'll leave you a hint.

These puzzles are made by Old Miles from China. If you want more of this kind, you can search teleportation sum. We call it sum with the x-th. Old Miles named it in 2018, so nobody shall tell me how to name this variant. I'll share the story in the hidden comment below.

Don't worry, the next one or two 9X9 are easier, Also, I got enough time to actually think of some good ideas(like this one). Funny every time I look back at Old Miles'puzzles, I can think of other new ideas. It still interested me why nobody eleborate the two cell series. I really hope some of the setters can go back to the orginal ideas and develop them, not just made a second puzzle. There are only that many Petlov here. Seeing exactly the same rule again and again is challenging my tolerance. A good sequel should make the solvers realize another side of the puzzle, not just the same tricks over and over again. In a word, I just don't want to see a variant go stale, overused and become a stepping stone for new setters.
