Also the thrill to try a new game lies in the secret how it works and how much it pays. I mean reading guide is not a bad idea but I would always prefer to make bets directly and try the game maybe with smaller amounts or as you mentioned with free demo.

Most of the games are really simple like dice although the calculation behind is hard to understand but the game itself is really simple, same goes with Plinko, Keno, slots and almost all games. There are a few slightly hard games like Bustabit or as some casinos call it as Blast or Crash because you have to understand when to cashout and what are the limits like how high the rocket can go before it crashes.
