How are they made? The answer is that they appear after many attempts, a lot of mistakes, numerous tests and upgrades of every gadget. It’s impossible to predict everything when you have only an idea. That’s why the main factor here is the production volume.
For instance, now our company produces approximately 15 escape rooms per month. For more than 5 years we have made dozens of copies of the same rooms and gadgets so we know all the imperfections and improve them with every new project. Personally, I test each element on the final step, trying to damage it. All the things that fail the test are remade so we can hit with them with a hammer and not to break it.
Meanwhile, I see that
less experienced suppliers produce gadgets which become non-functioning after 10-20 games.
