Grand Prix
(Published on 13. February 2023, 16:00 by Blobz)
Normal sudoku rules apply.
Digits in cages sum to the clue in the top left corner.
Two race cars (blue and green) start in box 1 and race around the track to the finish line in box 2.
Draw green and blue lines to show the paths that the cars take. Each checkpoint (cage) shows which cell each car passes through. The cars may not enter grey shaded cells, and must avoid all oil slicks (given digits). The paths cross exactly 3 times during the race. The paths do not share cells.
Digits along the blue path have an equal sum N within each box it passes through.
Adjacent digits along the green path must differ by at least 5.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Row 6 followed by Column 6

Truly awesome. Once you get the rules 1.5 starish. Very clever interactions. Great fun thx.

The setting of this is absolutely genius!
Not too hard to solve but that doesn't matter at all, it's an absolute pleasure to see how the logic flows and works with the 'story' of the puzzle.

I loved this puzzle so much! What great fun from start to finish and I never felt lost (until I overlooked a cage in the end and didn’t know how to resolve the last few digits

I always find line puzzles horrifically hard to solve, but after seeing the ratings (both beautiful AND easy-ish?!) and reviews (overwhelmingly positive!), I checked it out. And was NOT disappointed! It's amazing, tbh!

I usually do not do path puzzles as I find them quite difficult but this one was very enjoyable

I went off track once but was nonetheless able to finish with a reasonable lap time. Very nice racing :-)

Quite a banger. Either I´m too thick/inexperienced or the rating systems here are scary. I don´t even wanna try the 5 star puzzles. Anyhow, super interesting and fun, thanks!

I enjoyed this puzzle a lot. I found it very difficult, but I imagine I am an outlier since I am not used to path drawing puzzles.

This puzzle was VERY enjoyable and approachable. Thank you for setting it!

Perfect puzzle! Interesting ruleset and nice solve path throughout.
I would suggest to clarify that the racecars can go orthogonally and diagonally.

Loved it! Very nice flow and not too hard.

Phew, I managed to solve this without having any lap times deleted for track limit violations!
