When it comes to online gambling, unless you are playing games based on certain winning strategies, the common premise is that the entire action is of chance. There are hardly any tools or methods that would predict how the slot will roll its reels, or which card will the dealer take out of a shoe next.
And yet, even with games of chance, there are breadcrumbs that allow us, the players, to see if the game can be more or less advantageous. The most common signal is the game’s RTP — a long-term percentage of wagered money that can return to you in wins. The higher it is — the better. Some of the highest RTPs are for roulette and blackjack games.
Another very important parameter of the math model added to a game is its volatility. In plain terms, it is that mechanism that takes you on an emotional rollercoaster of winning and losing. Volatility can be either low or high. Up to a certain point, both of its variations can work to your advantage. In the long run, however, the casino wins.
The level of volatility tells you how a game could potentially work for you over several hours or days. High volatility offers that bit of the unexpected to gamers and is a huge appeal to many.
