The biggest mistake casual gamblers make is ignoring the underlying mathematical engine that drives the slot machine.

Understanding a game’s volatility is the absolute key to choosing a machine that matches your budget and your expectations.

The Difference Between High and Low Variance

Low variance games are perfect for players who want to relax and play for hours without losing their money quickly.

High variance games are incredibly risky; they will drain your budget rapidly, but offer the chance for life-changing payouts.

• High volatility slots often feature incredibly complex bonus rounds that are very difficult to trigger
• Low volatility games are the absolute best choice if you are trying to clear a casino bonus wagering requirement
• Megaways slots are notoriously high variance, offering thousands of ways to win but long periods of ‘dead spins’

Spotting the Signs of High Variance

If the game provider does not explicitly state the volatility, you can figure it out by studying the game’s paytable.

Furthermore, if the lowest-paying symbols don’t even cover the cost of your spin, the machine is highly volatile.

Matching the game’s mathematical profile to your personal bankroll is the secret to a successful casino session.
