My problem is at least other games have some benefits. Hand eye coordination, reflexes, critical thinking, problem solving skills, reading and comprehension skills.
Mobile games are designed to be as simple, accessible and most importantly easy as possible. They want you to feel like you're winning over and over and over with no real effort on your part. Obviously there are some exceptions, but still.
Do games count? I got scammed on runescape out of a 50mil item which was a lot at the time (this was sometime around 2003-2005). 50-100 hours of time for me to get it at an estimate. It was a stupid mistake that I thought I was smart enough to avoid, with what I now recognise as classic signs of a scam (slightly too good to be true, moving goal posts, slightly odd but not entirely unreasonable requests, time sensitive).
But I can tell you I'm glad I got scammed young on a game, because it was a good lesson with very low actual harm (only time lost realistically) and made me WAY more wary of things.
