I've just completed The Room Three thus ending the wonderful Room series. The plot was a bit shallow but I found the mechanical puzzles quite fascinating.
Now I'm looking for another puzzle game just like this. Without a plot, just the puzzles. You know, turn the box, flip the switch turn the key, work the cogs, etc.
Something like Cogs https://play.google.com/store/apps/details?id=com.lazy8studios.cogs but with Room like puzzle-boxes, mechanical apparatus and stuff.

Is there such a game?

I'm not a gamer but had a quick look
and found this

molly38 thank you for responding but that's not the kind of game I'm looking for.
There are about a thousand variations of 100 Doors and I'm not looking for a room crossing game (solve the puzzle, go to the next room, etc.)

I want a puzzle game with mechanical elements, just like the puzzles in The Room. Flip switches, turn keys, crank cogs, things like that... preferably in 3D.

I think you should give Lara Croft Go and Hitman Go a try.
