Escape from the Room with 10 Safes
Sounding more like the title to a 50s era popcorn muncher you'd see on some broadcast channel's late late show, Escape from the Room with 10 Safes by Hottategoya is decidedly tamer, shorter, and less edge-of-your-seat. Unless you are afraid of maths. As you gaze around the room and discover that ten safes actually amount to about ten algebraic puzzles, your opinion of whether this will be an enjoyable escape should be easily decided—either you're giddy at the chance to play with numbers or you're already disappointed, conjuring up images of your mean old Math Teacher from 9th grade.
See, that podium over by the door contains a short string of numbers and functions which you can change, given the right buttons, to equal a number on the front of each safe. Open the first safe, you'll get a new number button to replace any of the others to make a new equation to open the next safe to get a second number button and so on until all ten safes are open, earning you the key to the door, likely in a matter of mere minutes. In typical Hottategoya fashion, the room isn't much to look at, either; while not as imposing as The 5,000 Fingers of Dr. T, whatever your attitude toward mathematics, you will feel happily liberated once you succeed.
