Spot the Difference
(Published on 13. December 2023, 03:29 by marty_sears)
This is part 4 of my Differences series.
Part 1: Same Difference
Part 2: Different Differences
Part 3: Same Zifference
Part 4: Spot the Difference
Part 5: Diffambiguate
Part 6: Pseudo Differences
Part 7: Ziffer Spots
Part 8: Ziffers of Entropy
Part 9: Difference Diamonds
Part 10: Some Difference
Part 11: ???
Rules:
- Normal sudoku rules apply.
- Connect each pair of matching coloured spots with a snake. Snakes may only move orthogonally through the grid, not diagonally. They may touch each other (and themselves), but cannot share cells.
- Each pair of adjacent digits along a snake has the same difference, but this 'difference value' may be different for different snakes.
- A grey square contains an even digit.
- A black dot connects two digits with a 1:2 ratio (one is double the other.)

Way harder than I expected, but nice nonetheless.

Awesome puzzle. Needed help on the initial step. That was hard. Then true 4 star. Tricky not to stay full alert on every idea. Great journey. A true classic thx.

It's a beautifully constructed puzzle!
The break-in was too hard to find for me, so I resigned to watching the Cracking the Cryptic video on this for help. After Simon pointed me in the right direction to start, I paused and then was able to solve it without any problems. Very nice and smooth flow in the rest of the solve.

I have to disagree with some of the previous solvers. I think it was a very nice 3* difficulty. Thank you.

Phenomenal puzzle, took me a couple hours to solve so 5* difficulty but every step was logical and enjoyable!

Solved, but thought I'd ricketed no fewer than three times. Excellent solve, and relieved it's over.

Fabulous puzzle. I actually didn’t think the break-in was that hard (though it was the most awesome part in the literal sense). Though there was a particular… twist… leaving me wondering how I had broken the puzzle for a good long while. Diabolical.

This is hard! And fun!

75min for me. I think it should be 4* or more. The beginning of this puzzle is tricky haha~
