This article will find a straightforward guide about slot variance and its importance.

What is the Slot Variance?

It is a unit to measure the expected range between the winning and losing frequ3ncy in any slot game. In other words, slot variance is the estimated range of how your bankroll will last while you are playing while considering both winnings and losses.

A Brief Idea

Slot variance is often associated with long-term gambling sessions. For ease of understanding, imagine you are playing an online game. A graph is used to map and denote your game performance. The graph is plotted on a horizontal; axis, while a curved line denotes your winnings and losses. In this case, the dips are your losses, and the peaks are your winning rounds.

The graph would look like a line drawing of high mountains with deep valleys nestled between the peaks.

The slot game is of high variance if the line comes with sharp peaks and deep and wide dips. That means, while playing this game, a gambler may encounter frequent losses with a few large winning payouts.

On the contrary, the game is of lower variance if the line looks like a combination of a few undulations with blunt peaks and smaller dips. That means you will get multiple small payouts.

Types of Slot Variance

Usually, slot games come with three types of variances-

High Variance Slot Games:  High variance slots games have a rare chance of winnings. But the winnings are larger. Being high-risk games, these offer higher rewards.

Medium Variance Slot Games: Slot games with medium variances usually come with an average risk percentage. You win multiple times, but not too often. Moreover, the reward is often average-sized in these games, neither big nor small. It is a great choice for anyone who does not want to play a high-risk slot game but wants to win more often with good rewards.

Low Variance Slot Games: Online slots with low variance have the lowest risks. You can frequently win while losing is quite a rare thing. But, these games usually offer a low amount of rewards, mainly small winnings of a few dollars.

First, start with low variance slots to get a game habit if you are a beginner. Then scale from medium variance slots towards the high variance games.

Variance vs. Volatility

While these two are quite similar concepts, they are different. The variance is related to long-term gaming and winning, while volatility measures the risk factor for small-time gambling sessions.


The variance of slot games is the chance of winnings and losses in long-term gambling sessions. Slots can have high, medium, or low variance. Players need to consider the variance of slot games to manage their bankroll and winnings effectively.
