Spot the Difference

(Eingestellt am 13. Dezember 2023, 03:29 Uhr von marty_sears)

This is part 4 of my Differences series. I recommend playing them in order :)

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: ???


  • 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.)

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!

Simply brilliant!

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

I don't know how you come up with these puzzles but it is mindblowing. Abosultely incredible from start to finish.

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~
