I've seen this asked a million times on quora and reddit, but the answers don't seem so good. As for (law) stackexchange, it seems this has been asked only once in a case where apparently you can't lose.
Focus on games where you can lose (re question above). Like you don't get any tickets. Or you don't get enough tickets to win something.
Not every game in an arcade gives tickets like when you play time crisis or house of the dead. Exclude those. Focus on the ones where you do get tickets depending on your performance or luck (or both).
So far some answers I've seen involve:
Technically the prizes you get at arcades aren't money.
- Sub-question 1: Though you could sell the prizes?
The prizes' total value doesn't exceed the cost of obtaining such prizes.
- Sub-question 2: And if they did?
Something about games of skill vs games of chance, typical terms in gambling law, but these terms kind of bore me whenever I ask/read about gambling (eg this), so I didn't read further. Please avoid bringing this up if you don't mind. It's really boring.
