Understand cricket formats
Before betting on cricket, it is important to know the differences between the various formats. Betting markets vary across each format.
T20 Cricket
20 overs per innings, usually completed in 3–4 hours. BPL, IPL and T20 World Cup are played in this format. Betting markets move faster — ball-by-ball live betting is popular.
One-Day International
50 overs per innings, played over a full day. The ICC World Cup is held in this format. Top run-scorer and wicket-taker betting markets are popular.
Test Cricket
Matches last up to 5 days with unlimited overs per innings. You can bet on match winner, series score and first innings lead markets.
The Hundred
100 balls per innings, played in England. It is the fastest format and quite exciting for live betting.
Popular leagues: BPL (Bangladesh Premier League), IPL (Indian Premier League), BBL (Big Bash League), PSL (Pakistan Super League) — bet on matches from all these leagues at ko77.
Cricket partnerships — industry trends
Online casino and betting brands are increasingly investing in partnerships with cricket teams and players. This trend is especially noticeable in the Bangladesh and South Asian market.
Babu88 and franchise sponsorships
Babu88 has signed sponsorship deals with Montreal Tigers and Colombo Strikers. These kinds of partnerships are helping to build brand awareness in the South Asian cricket circuit.
Jeetbuzz and Andre Russell
West Indies star all-rounder Andre Russell has served as a brand ambassador for Jeetbuzz. This type of high-profile partnership has generated a strong response among Bangladeshi cricket fans.
Crickex and regional sponsorships
Crickex has sponsored various regional cricket tournaments across South Asia. This trend shows that the online gaming industry and cricket are now closely connected.
The information above is intended to illustrate general industry trends — it does not represent claims about ko77's own partnerships.
Football betting — in the world's best leagues
Football is growing in popularity in Bangladesh day by day. Bet on all matches in the Premier League, La Liga, UEFA Champions League and FIFA World Cup qualifiers at ko77.

Types of slot games
Before playing slot games, it is important to know about the different types of slots. Each has its own distinct features.
Classic slots (3-reel)
Old-style three-reel slots with simple gameplay and fewer paylines. A suitable starting point for new players. Pragmatic Play's classic series is worth noting.
Video slots (5-reel)
Modern five-reel video slots with bonus rounds, free spins and various themes. PG Soft's Fortune Tiger and Sweet Bonanza (Pragmatic Play) are popular in this category.
Jackpot slots (progressive)
A portion of each bet goes into the jackpot pool, which keeps growing over time. These games offer the chance of a big win.
Megaways slots
The size of the reels changes with each spin, creating thousands of ways to win. NetEnt and other providers produce games in this format.
Cascading reels
After a win, the matching symbols disappear and new symbols fall from above. There is a chance to win multiple times in a single spin.
Cluster pays
Instead of paylines, a win occurs when a cluster of matching symbols forms. Microgaming is known for producing games of this type.

What is RTP and house edge?
RTP stands for Return to Player — it is a percentage that indicates what portion of the total amount wagered on a game is returned to players on average over a long period. For example, a 96% RTP means that for every ৳100 wagered, an average of ৳96 is returned — but this is an average across millions of spins, not a guaranteed result for any single session.
House edge is the opposite side of RTP. If a game's RTP is 96%, then the house edge is 4%. This 4% represents the casino's expected long-term advantage.
Typical RTP ranges by game type: slot games generally offer an RTP of 92–98%. Card games like blackjack can reach an RTP of close to 99% when played with the correct strategy. Roulette typically has an RTP in the range of 94–97%.
Having an understanding of RTP and volatility (the level of risk in a game) before you play will help you make informed decisions. High-volatility games pay out less frequently but offer the chance of larger rewards, while low-volatility games deliver frequent smaller wins.
Quick comparison
| Game type | Typical RTP |
|---|---|
| Slot games | 92%–98% |
| Blackjack | ~99% |
| Roulette | 94%–97% |
| Baccarat | ~98.7% |
| Video Poker | 95%–99% |
* These are general industry ranges — RTP may vary for specific games.

Bankroll Management Guide
Smart gaming is not just about luck — it is also about planning. Bankroll management is that plan, helping you play longer and avoid unnecessary losses.
Start by setting a fixed budget — an amount that, if lost, will not affect your daily life. Divide that budget into smaller sessions. For example, if your weekly budget is ৳1,000, split it into 5 sessions of ৳200 each.
A common rule is to bet no more than 1–5% of your total bankroll per bet. Following this rule means even a bad run cannot wipe out your entire budget.
Practice stopping after a win. Set a specific target — such as a 20% profit — and end the session once you reach it. Likewise, set a maximum loss limit (for example, 50% of the session budget) and stop for the day once you hit it.
Keep a record of every session. When you played, how much you bet, how much you won or lost — this information will help you understand your playing patterns and make better decisions in the future.
Quick Tips
- Play only with money set aside for entertainment
- Keep each bet within 1–5% of your bankroll
- Set your win and loss limits before the session begins
- Avoid the temptation to place large bets to recover losses
- Track your playing history regularly
- Avoid playing when you are tired or under stress
Betting Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
A measure of what percentage of total bets placed on a game is returned to players over the long term. The higher it is, the fairer the game.
House Edge
The mathematical advantage held by the casino or bookmaker, calculated by subtracting the RTP from 100%. It is the source of the casino's long-term profit.
Wager / Stake
The amount of money you place on a bet is called the wager or stake. All bonus wagering requirements are calculated based on this amount.
Odds
A numerical expression of the probability of an event. The higher the odds, the larger the potential payout but the lower the probability.
Parlay / Accumulator
Combining multiple bets together into one larger bet. Every selection must win, but the total payout can be much larger.
Live Bet
The ability to place bets in real time while a match or game is in progress. Odds change continuously and decisions must be made quickly.
Cashout
The option to withdraw a confirmed portion of a bet before the match ends. Used to reduce risk and secure a guaranteed profit.
Bankroll
