Cricket Partnerships — An Industry Trend
The online betting industry is currently strengthening its presence through partnerships with cricket teams and players. This trend is making betting brands more familiar to cricket-loving audiences in Bangladesh.
For example, Babu88 has built relationships as an official partner of Montreal Tigers and Colombo Strikers in the International League T20. Crickex is reaching audiences through sponsorships in various regional cricket tournaments. Jeetbuzz has appointed the well-known Caribbean all-rounder Andre Russell as a brand ambassador, generating a strong response across South Asia.
These kinds of partnerships show that cricket and online betting are growing together. Every match featuring Bangladesh Tigers now brings fresh excitement to betting markets, especially during the T20 World Cup and BPL season.

RTP and House Edge Explained
RTP, or Return to Player, is a percentage that shows how much a game pays back on average per ৳100 wagered over the long run. For example, a 95% RTP means an average of ৳95 may be returned for every ৳100 bet — the remaining ৳5 is the casino's margin. This is a theoretical average; results in any individual session may vary.
RTP ranges differ across game types — typically 92% to 98% for slots, around 99% for blackjack, and 94% to 97% for roulette. A higher RTP means theoretically more returned, but it is not a guarantee of winning.
House edge is the flip side of RTP — it is the casino's mathematical advantage. If a game has an RTP of 96%, the house edge is 4%. The lower this number, the better it is for the player. In skill-based games like poker or blackjack, following the right strategy can reduce the house edge.
Understanding a game's volatility before you play is also important. High-volatility games offer big wins occasionally, but the chance of walking away empty-handed is also higher. Low-volatility games deliver smaller wins more frequently. Choosing a game that fits your budget and preference is the mark of a smart player.
Betting Terms & Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
RTP is a theoretical calculation of what percentage of total wagers a game returns to players over the long run. The higher it is, the more player-friendly the game.
House Edge
House edge is the casino's mathematical advantage — the percentage of each bet the casino keeps on average. Example: a 4% house edge means the casino earns an average of ৳4 per ৳100.
Wager / Stake
A wager or stake is the amount of money you put on a bet. A wagering requirement is the condition that you must bet a set number of times before receiving a bonus.
Odds
Odds express the probability of an event occurring — they show how much you will get back relative to your bet. For example, at odds of 2.5, a ৳100 bet returns ৳250 on a win.
Parlay / Accumulator
A parlay or accumulator combines multiple bets into one — you only win the total payout if all selections win. The risk is higher, but so is the potential reward.
Live Bet
Live betting, or in-play betting, means placing bets in real time while a match is in progress. You get the chance to make decisions based on how the game is unfolding.
Cashout
The cashout feature lets you secure a partial or full win before a match is over. It is a way to reduce risk when the betting situation changes.
Bankroll
Bankroll is the total amount of money set aside specifically for betting or gaming. Smart players always follow bankroll management.
Volatility
Volatility indicates the level of risk in a game. High volatility brings big wins occasionally; low volatility brings smaller wins more frequently.
Free Spin
A free spin is a no-cost spin in a slots game, usually given as a bonus or promo. Wagering requirements may apply to any winnings.
Spread Betting
In spread betting, you wager not just on who wins or loses, but on the margin. For example, in cricket you might bet on whether Bangladesh wins by 20+ runs.
Wagering Requirement
The condition that you must bet a set number of times before withdrawing a bonus or winnings. At bigtk, the welcome bonus wagering requirement is 20x — one of the best in the industry.
