What is variance in casino games?

ByCasinoFAQs

Variance in casino games describes how wins are spread out over time. It is also called volatility, and the two terms mean the same thing. You will see both used in slot reviews.

High variance vs low variance

A high-variance game pays out less often but the wins tend to be larger when they land. A low-variance game pays out more frequently with smaller wins. Medium-variance games sit between the two extremes.

This is separate from RTP (Return to Player). Two slots can share the same 96% RTP but have very different variance. One might pay small wins every few spins while the other goes 200 spins dry then delivers a large hit.

Why variance matters for your bankroll

With a limited budget, high-variance games carry more risk. You might hit a losing streak that wipes out your balance before any big wins arrive. Low-variance games extend your playing time because smaller returns come in more regularly.

High-variance slots suit players who can absorb losing runs. Chasing a large jackpot on a tight bankroll is a reliable way to leave a session with nothing. Understanding the house edge alongside variance gives you a more complete picture of a game before you sit down.

How to find a game’s variance rating

Providers do not always publish variance figures directly. The paytable is the fastest indicator. A slot with a massive jackpot symbol worth 5000x your bet but very low regular symbol values is almost always high variance. A slot where the top symbol pays 100-200x and regular symbols pay frequently is likely low or medium variance.

Review sites and a game’s info panel will usually describe it as low, medium, or high. Some providers like NetEnt publish a volatility score out of five on the game page itself.

Variance in table games

Variance applies to every casino game. Blackjack has low variance because outcomes per hand stay close to the bet size. Betting a single number in roulette is high variance because you win 35x your bet on that number or lose the whole bet on every spin. Table game side bets almost always add variance significantly.

Is high variance the same as low RTP?

No. Variance and RTP are different measurements. RTP is the percentage a game returns over millions of spins. Variance describes how those returns are distributed. A game can have high variance with a high RTP at the same time.

Should I play high-variance slots if I want big wins?

High-variance slots offer larger wins but also longer losing runs. With a small budget a losing streak can end your session before you see any return. They suit players with enough bankroll to ride out the dry spells.
