Honestly, I get bored with the old fruit games really fast. Sure, they don't eat your money instantly, but they just aren't as fun. I prefer modern games, but I just bet really small to keep my money safe. Just play what you enjoy!
For now I only play online, I was once or twice scheduled to go to the Casino with a colleague, but I never got there. My colleague had explained a few times how good it was, the sounds were bright, everything was lit up, he said that you could win more there, but I don't think that was the case, and I don't think I'll go to the Casino, I've had enough of online slots.
The special strat is to use the casino's money (bonuses) and play high volatility slots (pray you get lucky). Make sure to know the terms and that they don't have low win caps.
