No casino is ever worth playing for profit. It's worth playing for donations towards the casino or for the sake of doing something costly for absolutely no reason. Could you hit a jackpot? Yes, of course, and probably got a higher chance than winning the jackpot at lottery. If you base it on that, then again it is worth playing it more than the lottery is. However, in the long run, you will lose approximately 92-98% of the time. Some found ways of cheating the solid slots (not legally) and some people still find ways of cheating it in a legal way by watching and waiting, still a gamble. But online, I don't see how you could find an edge over the games..
