at casino, 80% odds is on house favor. I'm not really like to play at casino, even at landbased casino, i only play in slot.
That's funny!
You can't compare slots and roulette! With slots you just pres spin and of course, you adjust your bets, with roulette you have so many possibilities to bet on, starting from red/black, even/odd, to numbers that have higher payouts!
It's all about how you play roulette! I saw some people and their sense for playing roulette, how they search for numbers and place only number bets, to people who chase martingale with x2 and x3... Youtube is full of crazy roulette plays, take a look at them and you will see how interesting roulette can be!
First, I don't know where he got that 80% odds is on house.
Anyway, some people really don't see things here clearly.
I think, he needs to read this article just to get a better grasp between slots and roulette games.
And decide for himself, which game he will want to play with in the casino for his next visit.
