Reason #3 why the Wizard likes Bovada:

Excellent Odds

In my opinion many online casinos are too stingy when setting the odds on their games. They think they will make more money that way but I believe they are misguided, because when players lose too quickly it’s not fun, and those players might not come back.

Bovada is one of the few casinos that understands this. They offer generous odds to let you play longer and get you a better chance of winning. Among their generous offerings are Full-Pay Jacks or Better returning 99.54%, six other video poker games paying over 99%, single-zero roulette, and my favorite, Pick ’em Poker, returning 99.95%!

Kudos to Bovada for not being afraid to give their players a good gamble.
