In your opinion, which casino games do you think will give you the best odds of winning? I have always favored the Roulette table's dozens, columns and colored bets to cover a lot of numbers with a few wagers. Blackjack is OK also. I think that Slots gives you the worst odds which probably explains why a large chunk of a casino's profits is from the slot machines.
there is no specific game that gives you better odds , take dice as an example : house edge varies from site to site and if you play with the ones that have lower house edge you should be losing less
at the moment for casino games that don't involve dice I found that blackjack on bitcoinrush has the lowest house edge with 0.273% so playing there should give you better value than playing roulette or playing blackjack somewhere else
poker and sportsbetting are where money to be made , but that's a different story
