The Train and the Fly
(Published on 16. August 2024, 11:13 by marty_sears)
Rules:
- Fill the grid with digits, and draw a train that moves orthogonally through the grid and visits every cell once.
- The train consists of 4 carriages of equal length.
- A carriage doesn't touch itself, not even diagonally.
- Adjacent digits along a carriage are consecutive.
- An X connects the end cells of two carriages, which sum to 10.
- The black fly connects two digits with a 1:2 ratio.
- Identical digits may not touch each other orthogonally.
- A digit on the train indicates how many times that digit appears on the train.

This puzzle is mad.

An absolutely fabulous puzzle with all the great geometry you would expect in a Marty sears puzzle. I don’t think I ever figured out whether the train cars had to be a certain composition as described by BHUNTER47 but it’s nice that you can solve this either with more local deductions or thinking globally.

In a blind "guess the setter" challenge, I would guess Marty Sears was the setter of this puzzle every time.
That is to say, clever and unique idea, smooth logic and plenty of counting.

Needed some pen and paper notes before i got started. Then there was a Nice flow well constructed.
Facinating that there is a unique solution, fantastic construction.

It took some serious brain training to understand what was going on here, thoughts buzzing and flying around wildly before landing safely on the restaurant carriage's window. Amazing!

This felt for me like 4 stars, but it is brilliant puzzle either way. As expected from Marty another beauty!

It took me a while to get my head around the ruleset because it’s so original. Afterwards it felt so good how the funny deductions came out of my brain and I could solve this new MS-puzzle. So again, Marty Sears, thank you so much for creating and sharing another puzzle pearl.

Absolutely fantastic ruleset. I love how the way the rules were put together could lead to deducing the exact composition of all the train cells.

Great refreshing ruleset. Im not entirely sure at certain points whether my deductions where fully waterproof. But it felt right but everything was new to think through. Thx for sharing.

Got to be the first to test this. It is a great puzzle with multiple phases and some really fun logic throughout. Surprising this has a unique solution and that it is such a fun solve path.

Cute idea. Flows pretty easily once one understands the concept behind it :)
