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

Volatility, or variance, determines the risk level of the game, indicating how often and how much the machine pays out.

Decoding High Risk vs. Low Risk Slots

If a machine constantly gives you back half your bet or small profits every few spins, it is a low volatility game.

Conversely, a high volatility slot might not pay out anything for fifty spins, but then suddenly award a massive 1000x multiplier.

• 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

The fastest way to determine a machine’s behavior is to look at the maximum possible win multiplier.

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.
