What does 'risk of ruin' mean?

Risk of ruin is the probability of losing your entire bankroll before achieving a winning session. A 5% risk of ruin means roughly 1 in 20 sessions will result in losing everything. Most recreational players should aim for under 10%.

Why do slot volatility levels matter for bet sizing?

High volatility slots can go 200+ spins without a significant win. If you're betting too large, you'll bust before hitting those big wins. Lower stakes stretch your bankroll through the dry spells.

Should I change bet sizes during a session?

Generally, no. Chasing losses with bigger bets or increasing stakes during winning streaks are both mistakes. Stick to your predetermined stake size regardless of how the session is going.

Steps

Enter your total bankroll

Input the amount you've set aside specifically for gambling. This should be money you can afford to lose - never use rent money or emergency funds.

Select your risk tolerance

Be honest about how much variance you can handle. Conservative = longer sessions with smaller swings. Aggressive = higher potential wins but greater risk of busting.

Specify game type and session length

Different games have different variance profiles. A 2-hour slots session needs different stake sizing than a 30-minute crash game session.

Apply the recommendations

Use the calculated stake sizes and stop-loss limits. Adjust your actual betting to stay within these guidelines throughout your session.
