Educational Information
Bankroll Management Guide
Smart players do not just know strategy — they also manage their money wisely. The guidelines below will help make your gaming experience enjoyable and sustainable.
- Set a Budget: At the start of each month, decide how much money you are comfortable spending on gaming. This amount should never come from living expenses, savings or debt repayments.
- Session-Based Allocation: Divide your total bankroll into smaller session portions. For example, if you have 5 sessions per week, use 20% of the total for each one. Once a session's allocation is used up, stop playing for that day.
- 1-5% Per-Bet Rule: Place a maximum of 1-5% of your total bankroll on each bet. This way a single loss does not end the entire session and you can keep playing for longer.
- Stop-Win Rule: Set a specific target in advance — for example, end the session once your bankroll grows by 50% or 100%. It is wise to withdraw at the moment of winning rather than giving in to greed.
- Follow Loss Limits: If you lose 50% or more of your session allocation during a session, end the session. Trying to "chase losses" increases the chance of losing even more.
- Keep a Gaming Record: Write down each session's deposits, withdrawals and profit or loss in a simple notebook or spreadsheet. This will help you understand your own patterns and stay within budget.
