Cricket Formats Explained
Having a good understanding of the different cricket formats before betting makes it much easier to make decisions.
T20
Each team plays just 20 overs and a match usually finishes in 3–3.5 hours. This fast-paced format offers plenty of betting markets including pitch runs, over totals, and Man of the Match. BPL and IPL are played in this format.
ODI (One-Day)
Each team plays 50 overs and a match takes around 7–8 hours. The ICC World Cup is played in the one-day format. Half-time score, top batter, and bowler betting are popular markets.
Test
Strategy matters most in this five-day format. Alongside match betting, markets cover session runs, wickets, and individual milestones.
The Hundred
In this newer format from England, each team plays just 100 balls. The shorter match makes in-play betting particularly exciting.
Major Leagues
- BPL — Bangladesh Premier League
- IPL — Indian Premier League
- BBL — Big Bash League (Australia)
- PSL — Pakistan Super League
Cricket Partnerships and Sponsorships
An industry analysis of how online betting brands are engaging with the cricket market in Bangladesh.
Cricket sponsorship by betting platforms is growing rapidly in step with the popularity of international cricket tournaments. This is a global industry trend that increases audience engagement and builds brand recognition.
For example, Babu88 is widely known to have worked with the Montreal Tigers and Colombo Strikers franchises. Crickex has been seen as a presenting sponsor in various regional tournaments. Jeetbuzz has signed West Indies star Andre Russell as a brand ambassador.
This trend shows that cricket and online betting are becoming complementary in the Asian market. Betting activity in Bangladesh rises notably during the BPL season, as matches featuring local teams generate the highest levels of passion and excitement.

How Crash Games Work
A crash game (such as Spribe's Aviator) is a fast-paced multiplier game. Each round, a graph climbs upward and can "crash" at any moment.
You place your bet before the round starts. As the graph rises, the multiplier increases — you can "cash out" at any time. But if you don't cash out before the crash, you lose your entire bet.
Warning: Set a limit for yourself before playing and do not go beyond it.
Using the auto cash out feature, you can set an automatic cash out at a specific multiplier in advance. Each round lasts just a few seconds to a minute or two.
A Guide to Understanding RTP and House Edge
Understanding these two concepts before playing will help you make more informed decisions.
RTP (Return to Player) is a theoretical percentage that indicates what share of total bets a game returns to players over the long term. For example, if a slot game has an RTP of 96%, it means that theoretically ৳96 is returned for every ৳100 wagered — but this is an average across millions of rounds, not a guarantee for any single session.
House Edge is the flip side of RTP. A 96% RTP means a 4% house edge — this is the casino's long-term average profit rate. It covers the cost of running the games.
Typical RTP ranges by game type
- Slot Games 92–98%
- Blackjack ~99%
- Roulette (European) 94–97%
- Baccarat 98–99%
Remember: RTP is a long-term statistic. Results can vary in the short term. Knowing the RTP helps you set a budget, but it does not guarantee winnings.
Bankroll Management Guide
Smart players are good at managing their budget as well as winning. Follow the guidelines below.
Set a Budget
Decide in advance the maximum amount you can spend per month or per session. This amount should be money that, if lost, will not affect your daily life.
1–5% per bet
Professional players typically place only 1 to 5 percent of their total bankroll on each bet. This way, a big loss cannot wipe you out entirely and you retain the chance to recover.
Know When to Stop
Set a target after a win — stop playing once you reach it. Also set a maximum loss limit and end the session when you hit it.
Keep a Playing History
Keep a simple record of how much you have deposited, how much you have won, and how much you have lost. This will help you understand your playing patterns and make informed decisions.
Logic, Not Emotion
Avoid the urge to place larger bets to "chase losses" after a big loss. Decisions made in moments of frustration or excitement are often the wrong ones. Play with a clear head.
Play for Enjoyment
See online casino and betting as a source of entertainment, not a way to earn income. If you feel that gambling is getting out of your control, seek help on the Responsible Gaming page.
Account Verification Process (KYC)
Find out clearly why KYC (Know Your Customer) verification is required and how to complete it.
Why is KYC Required?
KYC verification is an international standard for preventing financial fraud, identity theft, and participation by minors on online platforms. It ensures the security of your account and avoids identity issues at the time of withdrawal.
What Documents Are Needed?
- National ID Card (NID) — photos of both sides
- Proof of address — utility bill or bank statement
- Selfie verification — a clear photo holding your NID
Processing Time
Verification is usually completed within 1–24 hours. Submissions on working days are generally processed faster.
After Verification
After successful verification, withdrawal limits increase and account security improves.
Tips
- Take document photos in a clear, well-lit place
- Make sure the name on your NID matches your account details
- If you have any issues, get help via 24/7 live chat
