Diamond Heist
(Published on 9. May 2025, 01:45 by marty_sears)
Rules:
Normal sudoku rules apply.
Escape from the diamond vault by finding a path from the ventilation shaft (r9c9) to the door (r2c1). Your path may only move orthogonally, and may not visit any cell more than once. You may not pass through any coloured display plinths. Also, stepping on any floor tiles with an even digit will trigger the alarms, so don't do that.
The digit on a diamond equals the sum of the digits on all the keys that match its plinth colour (and letter). No two diamonds have the same digit.
Discover these diamond digits to steal them, and find the path to escape the room. You have 45 minutes!
Please leave a comment if you enjoy :)
Solution code: Row 9 from left to right

Just found this one because of the CTC feature, so I decided to try it myself before watching the video.
Tons of fun! What a cool puzzle.

I cannot imagine how I missed this one. But now I found - and solved - it. Only five minutes left… Thank you very much for creating and sharing another lovely pathway puzzle.

Great puzzle, very, very enjoyable. The graphics are great too but perhaps the jewels are a bit too big/ominous on the sudokupad, making them a bit distracting when one uses the usual markings & colorings. That's just my 2cents suggestion for improving a wonderful composition. Thanks for sharing!

It was hard to see the digits from all those shiny diamonds But luckily I found my sunglasses and escaped with time to spare, was a great adventure!

That was a lot of fun! I managed to get 21:32, but admittedly made an educated, but lucky guess: I looked at two options and chose the one that would result in a more interesting-looking puzzle solution.

A lovely birthday gift! I escaped in just over 16 minutes!

Another absurdly well-made puzzle. Great fun!

oooh: 44:43, and I wasn't even looking at the clock plus dealing with random work distractions. I'll take it (and the diamonds)

Managed to finish in 28:32, yay! Wonderful puzzle as usual, thank you, Marty!

Didn't quite make it out in 45:00, but at least i did make it out!
on 9. May 2025, 18:19 by Drafuf
Woohoo i managed to get the diamonds in 44:24. Totaly forgot about the time restriction and needed to hurry in the end, when i finally remembered. That gave me an extra thrill XD
Now let's celebrate our succesfull heißt!
Thanks for this fantastic puzzle! I had lots of fun!

I've grown so accustomed to brilliant puzzles from Marty Sears that this excellent one came as no surprise. Thank you for it!

Managed this one with 15 minutes to spare for admiring the diamonds. All that rat run training is paying off...

Wow, I really enjoyed this puzzle. I don't usually do these with paths because I am bad at them, but I found the difficulty just right on this one. Highly recommended.

Really enjoy!!!

Gem of a gift for a gem of a setter!

Wonderful puzzle with hints of Finxz!
Getting the diamonds and the keys was easy enough, but plotting the path took me too long unfortunately - 64 minutes in total - so the police was waiting for me as I escaped.
Happy birthday, Scojo! Could you send me a piece of your birthday cake with a file hidden in it?

The race against time adds an extra dimension to a superbly crafted puzzle.
As always, great fun to solve!

Solved in 29:30 during Uni classes, was a lot of fun!

I just got caught while trying to run away (45:24). The chase at the end was real fun though!
on 9. May 2025, 04:00 by LunarOnSudoku
I'm afraid I wasn't able to beat it in the 45mins allocated and I was apprehended by the police far before I could, but they kindly let me finish it while I await trial for the diamond theft! (65:20)
Fabulous puzzle as always Marty!
