In the realm of online gambling, one may have encountered the term ‘variance’ as a player. This notion holds significant weight in casino games, as it possesses the power to influence both the course of your gameplay and the amount of money you are rewarded with. The following discourse shall explicate the nature of it, elucidate its mechanisms, and contextualize its impact on the player’s overall gambling experience.

Understanding Variance

Variance, otherwise referred to as volatility, is a statistical concept that denotes the degree of deviation from an anticipated outcome. In the context of online casino games, it serves as a metric for measuring the frequency and magnitude of wins and losses in a game. Games with a high variance are characterized by sporadic, albeit sizable payouts, whereas those with a low variance will offer more frequent but relatively modest payouts.

For instance, imagine that you’re engaged in a high-variance slot game. In such a scenario, it’s plausible that you’ll experience extended spells of losing and receive only minor payouts. However, when you do hit a winning combination, you stand to gain a substantial sum of money. By contrast, in a low-variance slot game, you’ll receive more frequent payouts, but they will be of a lesser magnitude.

How it Affects Your Gaming Experience

Variance can significantly affect the quality of your online casino gaming experience. In case you seek a game that delivers more excitement and sizable payouts, opt for a game with high variance. However, if you prefer playing for longer stretches and desire to extend your bankroll, then low variance games may be the better option.

Comprehending the variance of the game you’re playing is essential to effectively managing your bankroll. For example, if you’re playing a high variance game, you should brace yourself for losing streaks and adjust your bankroll accordingly.

How to Determine Variance in Casino Games

Determining the fluctuation of an online casino game can prove to be a formidable task. Nevertheless, certain metrics aid in approximating the deviation of a game. One of the most prevalent gauges is the return to player (RTP) rate. The RTP rate pertains to the percentage of the wagered amount that the game dispenses back to the player over a period. A game boasting higher RTP rates is predisposed to have lower variance, whereas a game with lower RTP rates is liable to have higher one.

Another manner to calculate variance is to scrutinize the paytable of the game. A paytable that features numerous high-yielding symbols alongside a handful of low-yielding ones suggests the game has high variance. Conversely, a paytable that showcases multiple low-yielding symbols and only a few high-yielding ones implies that the game has low variance.

Aside from RTP rates and paytables, providers of online casino games may also supply information concerning the fluctuation of their games.

How Variance Affects Bonus Offers

The effectiveness of bonus offers can be impacted by it, which refers to the level of risk and uncertainty involved in a game. For instance, a bonus offer that mandates you to wager the bonus amount a specific number of times may be more efficacious in a game with low compared to a game with high variance. This is due to the fact that low variance games generally offer payouts more frequently, enabling you to satisfy the wagering requirements more rapidly.

Conversely, a game with high variance may necessitate that you wager the bonus amount multiple times before fulfilling the wagering requirements, which can prove to be challenging and time-consuming.


After careful consideration, it is evident that it plays a crucial role in the realm of online casino gaming. A firm grasp of the variance associated with a particular game can have a profound effect on both your overall gameplay experience and the potential payouts you stand to receive. Whether you lean towards games with a high or prefer those with a lower degree of variance, it is critical to choose games that align with your personal gaming style and your strategies for managing your bankroll. By immersing yourself in the complexities of it, you will undoubtedly be better equipped to make well-informed decisions when it comes to selecting the games you wish to play and the bonuses that you may choose to accept.
