I may, from time to time, play a game of craps or casino poker, but for the most part I stick to the same four games, or some variation of them. I tend to stick to the blackjack tables, live poker games, online casino roulette, and (though I hate to admit it), online slot machines.
Here's a breakdown of each of my favorite casino games, and why fell in love with them. I'd love to hear about your own favorite game, or what you think of my ideas on these games, so leave me a comment and let's get talking.
Why I Love Blackjack
Blackjack was the first game I ever actually played in any casino, online or otherwise. I'm not counting the five card draw poker-for-pennies games we played in Boy Scouts. I'm talking about actual cash money on the line casino play. Since blackjack was my first game, I think of it as my first love. I may not always think about my first love, but I usually find myself coming back to blackjack, even if I've just had an hour-long session playing another 
game.
Blackjack is logical - I have a logical brain. Basic blackjack strategy helps you make the game decisions that will give you the best mathematical chance of winning. Is there any other reason to love blackjack? I feel like I'm most likely to win at online casinos when I play their blackjack games, so naturally this game is one of my favorites.
Why I Love Poker
I'm not talking about Casino War or any of the other you-against-the-dealer poker games, here. I'm talking about live head-to-head poker against other real players. Whether in tournament form or just at an open game on the weekend, I'm often easy to find at an online poker game. Part of my logical brain is drawn to poker - strategy and experience actually make you a better poker player - but really, the appeal is the psychological aspect of the game. Playing poker online, especially in large format on my television, lets me get out my competitive side.
Why I Love Roulette
Okay, so just because I'm a math guy and I know a ton about statistics doesn't mean that I can't occasionally play a risky game. Many roulette bets are admittedly risky. I think my love for roulette has more to do with the way the game looks on my huge flat-screen TV; the spinning wheel, bouncing ball, and croupier announcing the winning number appeals to my most base instincts. Roulette's the game I play when I want to take a break from the braininess of poker and blackjack.
Why I (Sometimes) Love Slots
This is the hardest thing I've ever had to type - I sometimes love to play online slots. Alright, so playing slots is totally based on luck and some online slot games are among the worst wagers on the site. But I do mind my manners and try to play at games that appear to give me at least a decent chance of winning. And, to be totally honest, most of my slot play comes on licensed games - I'm a geek, and when I see an online slot based on one of my comic book heroes, I have a hard time saying no.
