RAT RUN 6: Equilibrium
(Published on 10. July 2024, 01:00 by marty_sears)
- Normal sudoku rules apply: place the digits 1-9 once each in every row, column, and 3x3 box (marked with dotted lines.)
- AIM OF EXPERIMENT: Finkz the rat must reach the cupcake by finding a path through the maze. The path must not visit any cell more than once, cross itself, or pass through any thick maze walls.
- As well as moving orthogonally, Finkz may move diagonally if there's a 2x2 space in which to do so, but may never pass diagonally through a round wall-spot on the corner of a cell.
- TELEPORTS: Entering a yellow teleport will cause Finkz to be instantly transported to the other teleport. From there she can continue her journey. The teleports contain the same digit.
- ONE-WAY DOORS: Finkz may only pass directly through a purple arrow if moving in the direction the arrow is pointing. An arrow always points to the smaller of the two digits it sits between.
- BLACKCURRANTS: Cells connected by a blackcurrant have a 1:2 ratio (one is double the other.) Not all possible blackcurrants have been given.
- TEST CONSTRAINT: In this experiment, the sum of the digits on the path before teleporting must equal the sum of the digits on the path after teleporting.
Solution code: Digits NOT on the path in row 2 (from left to right)

Finally making my way through solving the puzzles myself. Incredibly enjoyable so far! I loved how I had to keep swapping between doing sudoku and thinking about the path logic.

Claiming another solve! Catching up is going to be easy if I just haven't claimed them all ????

Another great part of the series! For me, it was easier and quicker than the previous parts. I recorded a video of my solve for my YouTube channel -- please take a look! https://youtu.be/Q6Qg1EMVXI0

Blasted through that one, was a nice and smooth ride. Especially loved figuring out that path :3

my fastest rat run yet - 30 minutes and 30 seconds! found the breakin point really quickly, very satisfying

I thought this would be almost impossible when I started, but the break in was so very satisfying! Thanks for making this series <3

Spectacular variety and pacing!

Lovely puzzle, probably one of my favorite Rat runs!

Fantastic puzzle!

Great solve! These puzzles are addictive, can’t put my phone down! Very satisfying break-in, got it in just under an hour. Go Finkz!

very satisfying solve, my favourite so far

The variety of logic in this series is truly impressive!
on 19. August 2024, 05:53 by Nordy
Great fun as always, and extremely smooth once I remembered the teleports contain the same digit
on 19. August 2024, 02:41 by fajoogaloo
Very satisfying break-in. Simple, yet elegant logic. Continuing to enjoy the series, keep it up! :)

And again ❤️❤️❤️
Every puzzle from the series is absolutely amazing and great fun!

Delightful. What a wonderful series. Many thanks.

For Finkz's sake I really hope there was no fly in that teleport device. By the way, many thanks for the signed photo.

One of the most beautiful and fun break-in and solves. Simply wonderful
on 11. July 2024, 06:48 by Klausku
At first glance, this could not be a 2-star-path. But Finks quickly spotted something. Brilliant puzzle again. Thank you for this series.

Wonderful! Felt easier than the rest but no less enjoyable.

I so love these puzzles! Thanks so much marty sears!!
Wonderful storytelling in addition to the awesome concept.
For me this was very easy. I usually struggle a lot, but I immediately grasped the concept and them I solved it in 40 minutes. Which for me is like speedy gonzales (usually I take hours for 2 stars and days for 3 stars)
Thank you so much for your efforts to generate these beautiful sudokus!

Finkz continues her journey to boldly solve where no rat has solved before. Will she get chocolate cake instead of cupcake in the last one?
Marty: I'll have to see if there is a chocolate cake emoji :)

Absolutely sublime! I love that they've all been genuinely approachable while not sacrificing one ounce of beauty!
on 10. July 2024, 15:27 by OrcLord
Absolutely sublime with a truly satisfying solve just like the previous puzzles in the series.

Excellent again. Thanks

This series continues to be great. The break in is cool and easier than I expected when I read the rules.

Another brilliant addition to the series Marty! Finkz is quite the dab hand!
I recorded my solve for my channel youtu.be/NYx6ei4fRBg

Great fun! A lovely entry.
on 10. July 2024, 01:57 by sorryimLate
I guess the digit was teleported with Finkz? Well played, you almost made me doubt my sanity. Crazy fun puzzle again!
Marty: whoops! solution checker has now been fixed :)
