How to fix my tablet from restarting upon opening certain apps?

One month ago, I got a tablet. Some weeks ago I noticed it restarted upon opening some apps. These include: Geometry Dash, PacMan 256, Hill Climb Racing, Minecraft PE, Trippy Wheels, etc. I tried googling the problem and even looking on YouTube, but I didn't find what I was looking form, so I decided to ask here.
