Installation Errors On Android

I tried to download an APK for this game from a random forum and my phone blocked it saying it was unsafe. I really want to have an icon on my home screen. How do I install it safely without triggering security warnings?

Your phone blocked it for a good reason; those random files are dangerous. You should not install an unofficial Plinko App from forums. Instead, go to the official website in Chrome, tap the three dots, and select "Add to Home Screen". This creates a safe shortcut that looks and acts like an app but uses the secure browser version.
