Bankroll Management Guide
Set a Fixed Gambling Budget
Before you deposit, decide the maximum amount you can comfortably afford to lose each month. Treat it as entertainment spending, not an investment. Only deposit funds that are genuinely spare.
Divide Your Bankroll into Sessions
Split your monthly budget into smaller session amounts — for example, 10 equal parts. Once a session amount is spent, stop playing for that session. This prevents burning through your entire budget in a single sitting.
Apply the 1-5% Per-Bet Rule
Never stake more than 1-5% of your total session bankroll on a single bet. This extends your playing time and reduces the risk of ruin from a short run of bad luck.
Know When to Walk Away After a Win
Set a win target before each session — for example, 50% above your starting amount. When you hit it, withdraw your profit and close the session. Chasing higher wins after a good run often gives earnings back to the house.
Set a Hard Loss Limit
Decide in advance the maximum you will lose in a single session — typically 20-30% of your monthly budget. Once that limit is reached, log out immediately. Do not reload your deposit in the same session to chase losses.
Track Your Play History
Keep a simple log of your deposits, wins and losses each week. Reviewing real numbers helps you spot patterns, identify problem sessions early and make data-driven decisions about your gambling habits.
