Bankroll Management Guide
The most important part of responsible gaming is proper bankroll management. It not only reduces financial losses but also increases the enjoyment of playing.
- Set a Budget: Decide in advance how much money you can spend on entertainment each month. Do not exceed this limit.
- Divide into Sessions: Split your total budget into smaller sessions. Instead of spending everything in one session, save some for the next day.
- 1-5% Per Bet Rule: Use a maximum of 1-5% of your total bankroll on each bet. Taking too much risk can deplete everything quickly.
- Stop After Winning: Set a specific target. Once the target is reached, stop playing for that session and take your profit.
- Take a Break After Losing: After losing a set amount, take a break for the day. Rushing to recover losses is a serious mistake.
- Track Your History: Note down the deposits, withdrawals, and results of each session. This will help you understand your own habits.
Betting Terms / Glossary
Simple explanations of the most important betting and casino terms for new players.
RTP (Return to Player)
RTP is the percentage of total bets that a game returns to players over the long run. For example, a 96% RTP means that on average ৳96 is returned for every ৳100 bet.
House Edge
House edge is the casino's mathematical advantage, representing how much the casino retains from each bet over the long run. A lower house edge means a better opportunity for the player.
Wager / Wagering Requirement
Wagering requirement refers to how many times the bonus amount must be bet before it can be withdrawn. Example: 15x means you must bet 15 times the bonus amount.
Odds
Odds are the numerical expression of the probability of a specific outcome and how much you will be paid if that bet wins. Higher odds mean a higher payout but a lower probability.
Stake
Stake is the amount of money you are putting at risk on a specific bet. The higher the stake, the greater the potential win or loss.
Parlay / Accumulator
Combining multiple bets together is called a parlay or accumulator. All bets must win, but the reward is much higher if they do. If even one loses, the entire bet is lost.
Live Bet
Live betting refers to the ability to place bets while a match is in progress. Odds change every moment, which requires the ability to make quick decisions.
Cashout
Cashout refers to the option to exit a bet before the match or game ends. It allows you to secure a partial win or avoid a bigger loss.
Volatility
Volatility in a slot game refers to how frequently wins occur and how large they are. High volatility means fewer but larger wins; low volatility means smaller but more frequent wins.
Free Spin
Free spins are complimentary slot spins received as a bonus. You get the chance to win without spending your own money.
Bankroll
Bankroll is the total amount of money set aside specifically for gaming. Proper bankroll management is the foundation of responsible gaming.
Spread
In spread betting, a team must win or lose by a specific margin. Run spread betting is particularly popular in cricket.
