You should be specific on what you like, there are a lot of gambling games here such as blackjack, poker, dice, and if you love sports there's sports betting. I think you ain't different person, you also like what we like so just choose which game to enjoy. This is quite different because some are just seeking for recommendation on which site to gamble, but in his case he want different games.
I would suggest sports betting and poker. In case dice is something you have tried and still found it to be mostly a waste of time then you should try them. Though there are very few good and reputed sports betting websites out there people are always making some scam accusation against them. Dont buy into all the FUD.
Again sports betting can give the gambler and edge over others because they may know some inside news and its based on the gamblers skills and knowledge of the game.
Poker is really bad idea, because inexperienced player will lose everything in first few rounds of poker. Sport betting, if he likes any kind of sport is much better though, as he should already know some teams and can try to predict which team will win. Besides these 2, sport bets and poker, i don't think there are more fun ways to gamble. Stoshimines are fun i guess, but i'm sure that you've tried it already.
