International SponsorCrickex — Regional Sponsorship
Crickex has become a sponsor for several regional cricket tournaments in Bangladesh and the Indian subcontinent. This cricket-focused marketing strategy is becoming increasingly popular among online betting brands in South Asian countries.
Regional SponsorJeetbuzz — Andre Russell
West Indies all-rounder Andre Russell has served as a brand ambassador for Jeetbuzz. Associations with world-renowned cricketers like this help build trust for a brand within the cricket-loving betting community of South Asia.

Bankroll Management Guide
The most important aspect of responsible gaming is managing your money properly. Below are some proven strategies that will keep your online gaming experience controlled and enjoyable.
Set aside a fixed portion of your monthly income for gaming. This budget should never come from money meant for essential household expenses, savings, or debt repayment.
Break your monthly budget into weekly or session-based portions. For example, divide your monthly bankroll into four weekly portions and do not use one session's funds to cover another session's losses.
Never place more than 5% of your total bankroll on a single bet. Most experienced players follow a 1-2% rule, which increases the likelihood of staying in the game over the long term.
Stop playing once you reach a set target. Trying to maintain a "winning streak" often leads to losses. Set a goal and take a break once that goal is reached.
Decide in advance the maximum amount you are willing to lose per session. Once you reach that limit, stop playing immediately. Avoid trying to "chase losses" out of emotion.
Write down when you played, how much money, which game, and what the result was — in a notebook or spreadsheet. This information will help you analyze your gaming habits and make more informed decisions in the future.
Betting Glossary
A simple explanation of common online betting and casino terms for new players.
RTP (Return to Player)
The theoretical rate at which a game returns a percentage of total bets placed by players over the long term. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 wagered.
House Edge
The mathematical advantage held by the casino or bookmaker that ensures their profit over the long term. It is the opposite of RTP — House Edge = 100% – RTP.
Wager / Wagering Requirement
The number of times you must place bets before bonus funds can be withdrawn. For example, a 15x wagering requirement means you must wager ৳15,000 for a ৳1,000 bonus.
Stake
The amount of money you place on a specific bet is called the stake. The higher the stake, the greater the potential win or loss.
Odds
A numerical expression of the probability of an event occurring. For example, if Bangladesh wins at odds of 2.50, you receive ৳250 on a ৳100 bet.
Parlay / Accumulator
Combining multiple bets together into one larger bet. If all selections are correct, you win a large reward, but if any one selection is wrong, the entire bet is lost.
Live Bet
The ability to place bets in real time while a match is in progress. Odds change every moment, and you can make decisions based on how the match is unfolding.
Cashout
The option to settle a bet before the game is over. Depending on the current situation, you can secure a partial profit or reduce a potential loss.
Volatility
The level of risk in a slot or game. High volatility games pay out less frequently but offer larger rewards. Low volatility games pay out more frequently but with smaller wins.
Free Spin
The opportunity to spin a slot game at no cost, usually given as a bonus or promotion. Winnings from free spins can be withdrawn subject to wagering conditions.
Spread
In sports betting, wagering on the margin between two teams. For example, to win on Bangladesh at a -1.5 run spread, they must win by at least 2 runs.
Bankroll
The total amount of money set aside for gaming. Healthy bankroll management ensures an enjoyable gaming experience over the long term.
