The money you set aside as your play budget, ideally split into session bankrolls. Bet size as a share of bankroll largely decides how likely a session is to bust.

Why it matters

Bet sizing is the single biggest lever on bust risk.

In practice

Split your bankroll into session bankrolls so one bad night can’t use up a month’s budget. Keep winnings out of the next session’s bankroll. See bankroll management for a full plan.

Example

$50 session bankroll, $1 bets (2%).
