Normal sudoku rules apply.

Killer: digits in cages must sum to the clue in the top left corner.

Renban: digits along the pink line are consecutive but in any order.

German Whisper: adjacent digits along green lines differ by at least 5.

Region Sum: for each blue line, digits on the line have an equal sum N within each box it passes through. If a line passes through the same box more than once, each individual segment of such a line within that box sums to N separately.

Modulo: Every three adjacent digits along the orange line must be drawn one from each modulo group: {1,4,7}, {2,5,8}, {3,6,9}.

After breaking it several times thinking the orange line was entropic I finally solved it. Lol. Great puzzle.

Like the idea of using 3 with all possible constraint. Good that German Whisper is still difference of 5 and not 3. :)

Indeed a very good training for beginner to understand the different line types, I'd really enjoyed it, thanks a lot!

What a fun puzzle! I thought it was a nice showcase for these different rule types. Was gonna rate it 1* difficulty but a clever deduction near the end tripped me up so I'm bumping it up to a 2. Thank you for sharing!
