This kind of game can indirectly teach children about gambling because they buy coins with a certain amount of money to play in certain games. If they can't win, they lose the coins and have to use another coin if they want to play.
If you looked that way then it's gambling, if your children use skill to try to get a doll then its a game, it's more challenging than slot because you need timing here and you need to know the right doll to claw, I have seen a lot of tricks on how to claw dolls, it's not cheating but you need skill and timing to do this, so your children that you can get things through timing and right method to use.
In some countries, such games are prohibited because games can be equal to gambling, leading to addiction in children.
It's legal here in our country and it's included in a game and theme parks some Mall here in our country included this game and we have seen it in many recreational parks here, I guess its how every country define this kind of game
What's your thought? Have you ever played this kind of game?
I played this on one occasion but I got irritated seeing I cannot even get one doll while in ten tries other kids got theirs in one or two tries I thought that might as well buy one instead of getting myself embarrassed
