Description
You are not a player.
You are a test subject.
Welcome to MACHINE TRIALS, a mysterious survival experiment inside a dangerous industrial facility.
A powerful machine system controls every challenge. Each trial puts your reactions, timing, memory, and decision-making skills to the test.
Enter unknown rooms. Learn the rules. Avoid deadly mechanisms. Complete the objective. Survive the next experiment.
Every round brings a new challenge. Some tests require speed. Others require precision, patience, or quick thinking when everything goes wrong.
But you are not alone.
Other test subjects are trapped inside the facility, competing for the chance to continue. Work together when necessary, overcome obstacles, and prove you are the one who can survive.
As you progress deeper into the facility, new questions emerge.
Who created the machine? Why are these trials happening? What is the system trying to discover?
FEATURES:
- Unique survival trials - Fast and intense challenge rounds - Dangerous industrial machines - Tests of skill, timing, and strategy - Mysterious experimental facility - Simple controls, difficult mastery

Do not download this because it has WAY too much pop-ups like sometimes when u get on the app the pop-up covers the go button so u have to wait until the pop-up is gone to play, and I can't play it any more like when I try to play and song it says please connect internet connection when am connect to Wi-Fi

Edit: The games ads make this unplayable for me now. I can't even open the game and click play because of an ad that won't go away and blocks half the screen. It's an amazing game otherwise
