ODI (One-Day)
50 overs per team, a full-day match. Betting markets for Bangladesh vs India ODI matches include: match winner, series winner, top run scorer, wicket taker, type of first wicket, and more.
Test
A long format played over 5 days with two innings each. Betting markets include: probability of a draw, wickets in the first session, and series result. More opportunities for strategic betting for patient bettors.
The Hundred
A newer format — 100 balls per team. Even faster than T20. Popular in England, with a growing international audience. Dynamic in-play options are available in the betting markets.
Popular Cricket Leagues
BPL (Bangladesh Premier League): The Tigers' home T20 league. A chance to watch local and international stars play together.
IPL: India's Indian Premier League is the world's biggest T20 league. It also offers the highest number of betting markets.
BBL: Australia's Big Bash League — when cricket season is quiet in cities like Dhaka, BBL is a good alternative.

RTP and House Edge Explained
Understanding RTP and house edge is important for making better long-term decisions in betting and casino games.
What is RTP?
RTP, or Return to Player, is a percentage that indicates how much of the total amount wagered on a game is paid back to players on average over the long run. For example: if a slot has an RTP of 96%, then theoretically an average of ৳96 is returned as winnings for every ৳100 wagered. However, this is an average across millions of spins — results in a single session can vary.
What is House Edge?
House edge is the flip side of RTP — the casino's long-term mathematical advantage. If RTP is 96%, then the house edge is 4%. This means the casino retains an average of 4% from each bet. The house edge is never zero — it is the foundation of an online casino's business. As a player, the lower the house edge, the more favourable it is for you.
Typical RTP by Game Type
RTP ranges commonly seen across different game categories: slot games generally range from 92% to 98%; blackjack can reach close to 99% when the correct strategy is followed; roulette (European) typically falls between 94% and 97%; baccarat offers a comparatively higher RTP on the banker bet. Andar Bahar and Teen Patti RTP varies depending on the variant.
Why Does This Matter?
Understanding RTP and volatility (high vs low) helps you choose the right game for your budget and playing style. High-volatility games offer a greater chance of big wins but wins occur less frequently. Low-volatility games offer a greater chance of smaller but more frequent wins. Understanding this difference is the first step toward responsible gaming.
Fast Withdrawals
Withdrawals at tk11b are generally processed within 30 minutes to 3 hours. The minimum withdrawal amount is ৳1,000. Following the tips below will help speed up your withdrawal.
Keep your account verified: Complete KYC verification in advance. Withdrawals on unverified accounts may be delayed.
Make sure names match: The name on your bKash/Nagad/bank account must be the same as the name on your tk11b account.
Complete bonus wagering: Withdrawals will be held if bonus wagering requirements have not been met. Keep your bonus balance and real balance separate.
Avoid peak hours: Processing may take a little longer during busy evening and night hours. Submitting a request in the morning is generally faster.

- If playing on a shared phone, log out at the end of your session and do not save your password.
