Cricket Sponsorships & Team Partnerships
The online betting industry has deep ties with professional cricket — here's how it looks across the Bangladesh market.
Sponsorship between online betting platforms and professional cricket teams has become a defining feature of the South Asian gambling landscape. In Bangladesh in particular, the Bangladesh Premier League (BPL) and bilateral series featuring the Bangladesh Tigers generate enormous betting interest, and operators compete aggressively to align their brands with the sport.
Across the broader regional market, several well-known examples illustrate this trend. Babu88 secured sponsorship agreements with the Montreal Tigers and Colombo Strikers in franchise T20 competitions, giving both teams and the brand significant exposure among South Asian cricket audiences. Crickex, another BD-focused operator, has run regional sponsorships tied to local cricket academies and streaming partnerships. JeetBuzz signed West Indian power-hitter Andre Russell as a brand ambassador, a move that resonated strongly with BPL fans who watched Russell compete for the Khulna Tigers and other franchises.
The broader global picture includes Betway's long-standing ICC partnership, which placed betting brand visibility across major international tournaments including the T20 World Cup. Dream11 — India's dominant fantasy cricket platform — has been the title sponsor for IPL seasons, normalising the link between cricket and real-money gaming across the subcontinent. For Bangladesh-based bettors, these industry-wide partnerships signal that betting on cricket is a mainstream, well-established activity rather than a niche pursuit.

RTP & House Edge Explained
Return to Player (RTP) is the percentage of all wagered money that a casino game will pay back to players over a very large number of rounds. For example, a slot with an RTP of 96% will, on average, return ৳96 for every ৳100 wagered across its entire play history. It is a long-run statistical average — not a guarantee for any single session — but it is the single most useful number for comparing the theoretical value of different games.
Different game categories carry very different RTP ranges. Video slots typically land between 92% and 98%, with most reputable Pragmatic Play and PG Soft titles sitting at 96%–97%. Classic blackjack, when played with basic strategy, offers an RTP close to 99.5%, making it one of the best-value games in any casino. European Roulette sits at approximately 97.3% (house edge 2.7%), while American Roulette drops to 94.7% due to the extra double-zero pocket — a meaningful difference over time. Live baccarat (Banker bet) runs at around 98.9%, which explains its enduring popularity across Bangladesh and the wider South Asian region.
The house edge is simply the flip side of RTP: a 96% RTP game carries a 4% house edge. This is how the casino makes its margin across millions of bets. Understanding house edge helps you make more informed decisions — for instance, choosing a 97% RTP slot over a 92% RTP slot meaningfully extends your expected playtime on the same budget. Crash games like Aviator typically advertise a 97% RTP, though their high-volatility nature means individual session results vary dramatically.
At 677b, all published RTP figures are sourced directly from the game providers and verified by independent testing laboratories. We encourage every player — from Rangpur to Cox's Bazar — to check the RTP of a game before committing their bankroll. Choosing higher-RTP titles, combining that knowledge with disciplined bankroll management, and understanding variance and volatility are the foundations of a smart, enjoyable gambling experience.

Betting Glossary
New to online betting? Here are the key terms every 677b player should know before placing their first wager.
The theoretical percentage of wagered money a game returns to players over time. A 96% RTP slot returns ৳96 per ৳100 staked on average across millions of rounds.
The mathematical advantage the casino holds over players, expressed as a percentage. A game with 96% RTP has a 4% house edge — this is how the platform sustains itself long-term.
The amount of money you place on a single bet or spin. Your stake is at risk during each round and is returned plus winnings if your bet is successful.
A numerical representation of the probability of an outcome and the potential payout. Higher odds mean a less likely outcome but a bigger reward if it occurs — common in cricket and football betting.
A single bet that links two or more individual selections. All selections must win for the bet to pay out, but the odds multiply — making parlays high-risk, high-reward wagers popular during BPL season.
A wager placed after a match or game has started, using live odds that change in real time. 677b offers live betting on cricket, football, and other sports as events unfold.
A feature that lets you settle a bet before the event concludes — either to lock in a profit or cut a potential loss. Available on selected markets at 677b during live events.
The total amount of money you have set aside specifically for gambling. Good bankroll management — never wagering more than 1–5% per bet — is the foundation of responsible play.
Describes how often and how large a slot or game pays out. High-volatility games pay rarely but in big amounts; low-volatility games pay more frequently but in smaller amounts.
A bonus feature in slot games that lets you spin the reels without deducting from your balance. Free spins can be awarded by the game itself or as a promotional bonus from 677b.
The number of times you must bet a bonus amount before withdrawing winnings derived from it. A ৳1,000 bonus with a 30x requirement means you must wager ৳30,000 in total before cashing out.
A type of wager where you bet on whether an outcome will be above or below a range set by the bookmaker. Profits and losses depend on how far the result moves beyond the spread — popular in cricket run-line markets.
