A recommended bankroll size for a casual player typically ranges from 20 to 50 times the average bet they intend to make during a gaming session. This allows for enough cushion to absorb potential losses while maintaining the ability to enjoy the experience without the pressure of depleting funds quickly. For instance, if a player plans to bet $10 per hand, a bankroll of $200 to $500 would be advisable. This approach ensures that casual players can enjoy their time at the casino without risking significant financial stress, fostering a more enjoyable and responsible gambling experience.
