Bankroll Management Guide
Responsible bankroll management is the single most important skill any gambler can develop. The guidelines below are based on widely accepted best practices — they help you stay in control, protect your finances, and enjoy gambling as entertainment rather than a financial strategy.
Set a Fixed Gambling Budget
Before you deposit, decide the maximum amount you are comfortable losing in a given month — and treat that figure as entertainment spending, not an investment. Never use rent, food, or bill money. Players in Dhaka and Chittagong often find it helpful to set a dedicated bKash or Nagad wallet for gambling funds only.
Divide Your Bankroll Into Sessions
Split your total monthly budget into individual session amounts. For example, a ৳5,000 monthly budget could be divided into ten ৳500 sessions. This prevents you from exhausting your entire bankroll in a single sitting and keeps play sustainable throughout the month.
Apply the 1–5% Per-Bet Rule
Each individual bet or spin should represent no more than 1–5% of your total session bankroll. If you are playing with ৳500 for a session, keep each stake between ৳5 and ৳25. This rule naturally extends your play time and reduces the variance impact of any single outcome.
Know When to Walk Away After a Win
Set a profit target before you start — for example, "I will stop when I have doubled my session budget." Once you hit that target, pocket your winnings and log off. Chasing bigger wins after a good run is one of the most common ways players give back their profits.
Stop After Hitting Your Loss Limit
If you lose your session amount, stop immediately and do not top up. Chasing losses is the fastest route to financial harm. Log your session result, take a break, and return only during your next scheduled session — never the same day after a full loss.
Track Your Play History
Keep a simple record of deposits, withdrawals, and session outcomes — even a basic spreadsheet works. Reviewing your history monthly gives you an honest picture of your gambling habits and helps identify any patterns that might need attention before they become problematic.
RTP & House Edge Explained
Return to Player (RTP) is the percentage of all wagered money that a game is designed to pay back to players over a very large number of rounds. An RTP of 96% means that, theoretically, for every ৳100 wagered across thousands of spins, ৳96 is returned in winnings. It is a statistical average across millions of rounds — not a guarantee for any individual session.
House Edge is simply the inverse of RTP — the mathematical advantage the casino holds over the player. A game with 96% RTP has a 4% house edge. The lower the house edge, the better the long-term value for the player. Understanding both figures before you play is one of the smartest habits a gambler can develop.
Higher RTP does not mean you will win more often in a short session — variance (volatility) plays an equally important role. A high-variance slot might have a 97% RTP but pay out rarely, in large bursts. A low-variance slot at 94% RTP might pay small amounts frequently. Matching volatility to your bankroll size is just as important as comparing RTP numbers.
| Game Type | Typical RTP | House Edge | Volatility |
|---|---|---|---|
| Video Slots | 92–97% | 3–8% | Medium–High |
| Progressive Jackpot Slots | 88–94% | 6–12% | Very High |
| Blackjack (optimal play) | ~99% | ~0.5% | Low |
| European Roulette | ~97.3% | ~2.7% | Medium |
| American Roulette | ~94.7% | ~5.3% | Medium |
| Baccarat (Banker bet) | ~98.9% | ~1.06% | Low |
| Andar Bahar | ~97% | ~3% | Low |
| Aviator (Crash) | ~97% | ~3% | Variable |
RTP figures are indicative industry averages. Actual values vary by game title and provider. Always check the individual game's info panel for its certified RTP figure.

Legal Notice & Disclaimer
ok37 is operated by an internationally licensed offshore entity. The platform holds a gaming licence issued by its operating jurisdiction and complies with applicable international online gambling regulations.
Bangladesh's Public Gambling Act of 1867 was enacted long before the internet existed and does not contain explicit provisions governing online gambling by individuals. The legal status of online betting for personal use in Bangladesh therefore exists in a grey area that has not been conclusively resolved by domestic courts or legislation.
Players are solely responsible for determining whether accessing and using ok37 complies with the laws applicable in their own jurisdiction. ok37 does not provide legal advice, and nothing on this website constitutes a representation that use of this platform is lawful in Bangladesh or any other territory.
An 18+ age restriction is strictly enforced. Gambling should be enjoyed as a form of entertainment. If gambling is causing you financial or emotional distress, please visit our Responsible Gaming page immediately.
