I prefer flash casinos with no downloads. Great bonuses or great winning opportunities. Just good fun. Anyone know of any online casinos that offer really good chances of winning and really good bonuses?

   

You can check http://www.thebonuses.com for online casino bonuses. There are several lists there for all types of bonuses. As far as luck goes, if you find any let me know. I play the jackpot slots, the only way to win in my opinion is to win the jackpot.

   

If you like flash, I think there's one called "Jackpots in a Flash"
Bonuses differ a lot from casino to casino and I think the payout rates are more or less the same at all online casinos.
I would advise you to look at hypercasinos. Over there players give their opinion to other players.
