Of course, gambling for fun means you don't expect any winnings when you play at the casino, you just enjoy what you do by gambling at any casino.
No heart feelings about the amount you lose when you gamble.
You have no other reason but to just have fun playing at any game provider at the casino,
I can't think of anything else besides what I've already mentioned.
Do you think gambling for fun exists? For me I don't think such can happen, because I know quite well that so many of us who gamble doesn't gamble for fun, they gamble because of profit making not for fun, we have so many people who gamble on casino games, take your good time to investigate them by asking them a random question of the reason why they gamble, or you do a questionnaire go to any university or street to ask people the reason they gamble, you will see that most of the questions will be that they gamble because of winning or profiting in the gambling.
