Aha! I like the way how 27 cage is forced. Excellent arrangement.

Fun and approachable, 2 star solve time, but indeed one tricky step halfway through. Thanks!

Great puzzle! Funny to see the variety of responses, it’s not often you get a range of difficulty for just killers and thermos haha. I solved it in 8 mins and I consider it a two star because it had some steps I got quicklybut would consider a little tricky so I can see how I’d have gotten stuck on a different day!

very easy - until you hit a brick wall ...
until you realize that there's some hidden geometry, and the thing you absolutely didn't want to look at is actually the key.
prove that the 27 cage must contain AT LEAST 5-6-7-8.
the rest is very easy

Incredible setting. I managed to solve in a "2* time frame" but i was lucky to spot a mid-game break-in that i think many will struggle to find quickly, so rated 3*. Very impressive setting. Bravo.

Very nice but maybe 3 stars difficulty as it took me 59 minutes!
