It was installed without my knowledge, which makes me suspicious...

When I opened Playo today, there was an unknown game in the 'Continue Playing' section. What is this??? I couldn't find it on my phone's home screen, so I kept swiping to the very last screen that I don't usually check, and there it was! What on earth is this???? Yesterday, while playing a different game, I saw an ad within that game, and I vaguely recall seeing a commercial for this 'Paranoid' too... But I was taken to Google Play and didn't install it. Even if I had miraculously made consecutive accidental taps and installed it, on my phone, after installation is complete, it moves to a security check screen, and it never automatically returns to the initial ad screen from there... There's no way I wouldn't have noticed, right? I first touched my phone today just 5 minutes ago, and besides, I usually keep this phone in airplane mode with all mobile data and WiFi turned off... Has anyone else experienced a similar phenomenon with this game? Or if anyone knows why this might have happened, please tell me 🙏 Honestly, I'm too scared to play it...
