As you log in to spin the reels of a video slot, you see loud music, exciting themes, and the hope of a big win. Yet, behind the beautiful exterior lies a complex mathematical engine. Two absolutely vital terms dictate exactly how the game pays out: RTP percentage and the slot's volatility. Understanding these two metrics is the most important step for proper bankroll management and maximize your casino experience.
Defining the RTP Percentage
The Return to Player percentage is a statistical percentage that shows how much of the total bets a game will return to the gambling public over an extremely long period of time. For instance, if the game's return rate is 96 percent, it means that theoretically, for every hundred dollars pushed through the machine, the slot gives back $96 in payouts. The leftover $4 represents the casino's profit margin. You must understand that RTP is calculated over a massive sample size, so it will never dictate what happens today.
The Risk Level of a Slot
While RTP tells you the total amount returned, game volatility dictates the behavior of the payouts. Volatility is essentially the risk factor attached to the algorithm. A game with low variance will pay out very frequently, but the prize amounts will generally be quite small. These games are perfect for players with small bankrolls who want to stretch their playtime. On the other hand, a high volatility slot can experience massive losing streaks where you lose constantly. Yet, when the bonus lands, the jackpots are enormous.
Always check the RTP before playing; a decent return rate for modern online slots should be 96% or higher. You need deep pockets for high variance to get through the inevitable long losing streaks. Progressive jackpot slots usually have maximum variance algorithms and slightly lower base game RTPs. If you want to clear a casino bonus, always choose low volatility games to minimize your bankroll swings.
Matching Volatility to Your Bankroll: Which Slot to Pick
To make things easier, look at the table below that explains the behavior of different volatility levels and the ideal gambler should be playing them.

Ultimately, the best slot does not exist. The best choice depends entirely on your risk tolerance and your budget. If you want a relaxing evening with constant action, play low risk games. If you want to win a life-changing sum of money and you accept the risk, then high volatility is the only way to go. Knowledge is power; know what you are playing!
