If the online casino was operating illegally in your jurisdiction at the time of your betting, then you may be able to reclaim your money, thus you need to find out the dates that this became in effect. You would need to do some investigation work....document the dates of all your betting - and, if this is the case, then you can write them a letter, providing this information, and request for them to forward said monies to you. You can ask them to respond within 30 days, otherwise, you will seek legal action. If they don't respond, you can seek an attorney to assist you, or handle this yourself by filing a complaint for money against them. Otherwise, naturally, if they were operating legally in your jurisdiction at the time of your betting, then it would appear that you would not have any grounds whatsoever to reclaim your money. (Note: this basically comes down to the fact if "you" violated any laws by gambling on the internet in your jurisdiction - as others may be off limits as well, thus placing you in an uncompromising situation should you pursue this matter). (Know that making or accepting a wager over the Internet is now, by statute, a crime committed in Nevada, unless the operator is one of the state's licensees. Unfortunately, I do not have complete access to do research concerning the laws of your State - thus, please investigate thoroughly).
