I strongly believe that a lot of these new mobile games are heavily influencing kids to gamble. Their minds get very stimulated when they win virtual items like points, achievements, or gems. This isn't necessarily a bad thing though, as long we we teach them to gamble responsibly and treat it as a side hobby.
This is actually true. There are several articles that I have read that links video games/mobile gaming to gambling. They said that it unlocks the world of gambling for young minds.
I can testify that the same feeling when spending money on games is the same as when I am spending my money on gambling. It gives me a sense of accomplishment to win in gambling as the same way as when I am ranking up on my games. It's toxic and addicting when left unmonitored.
