I'm not sure why you put the pure-luck-or-not aspect on par with the addictiveness. People can get addicted to winning, regardless of if it's due to their skills or just luck.

The problem with e.g. slot machines is that anyone can win, with the same odds, so it's easy to get addicted to it. You can't get addicted to winning at golf unless you're already putting the work to get good at it. With slot machines you can win, without doing any work. That's the catch.
