Cricket Sponsorships & Betting Brand Partnerships
The relationship between online betting platforms and professional cricket has grown significantly across South Asia. Here is a factual look at major sponsorship trends relevant to Bangladeshi cricket fans.
Cricket is the dominant sport in Bangladesh and the commercial ties between the sport and online betting operators have expanded rapidly since the launch of the Bangladesh Premier League (BPL). Operators across South Asia now regularly align with cricket for brand visibility and player acquisition.
Babu88 secured official shirt sponsorship with the Montreal Tigers and Colombo Strikers in the inaugural Lanka Premier League (LPL), marking one of the first direct shirt deals between a Bangladesh-focused betting brand and a major T20 franchise. Crickex, another operator targeting the Bangladesh and India markets, has pursued regional digital partnerships across streaming platforms that broadcast IPL and T20 World Cup content. Jeetbuzz made headlines by signing West Indian all-rounder Andre Russell as their regional brand ambassador, a move that significantly elevated their profile with Bangladeshi cricket fans who follow the IPL and Caribbean Premier League.
These industry trends reflect the strong overlap between live cricket betting and fan engagement in Bangladesh. Platforms like 5666b serve Bangladeshi players who follow the Bangladesh Tigers in ICC events, the BPL season, and every IPL match with equal passion. Live in-play markets, ball-by-ball odds, and same-match parlays have become the standard expectation for cricket bettors in Dhaka, Chittagong, Rajshahi, and Sylhet.
- Bangladesh Premier League (BPL)
- ICC T20 World Cup
- Indian Premier League (IPL)
- ICC Cricket World Cup
- Bangladesh Tigers — All Formats
- Caribbean Premier League (CPL)

Legal Notice & Regulatory Context
5666b operates as an internationally licensed online betting and casino platform, hosted and regulated offshore under the jurisdiction of its licensing authority. The platform does not hold a specific Bangladesh domestic licence as no formal online gambling regulatory framework currently exists in Bangladesh.
Bangladesh's primary gambling legislation — the Public Gambling Act of 1867 — was enacted before the internet existed and does not explicitly address online betting conducted through offshore platforms. The legal status of offshore online gambling for individual Bangladeshi users therefore sits in a grey area that has not been formally clarified by the courts or legislature.
Users are solely responsible for understanding and complying with the gambling laws applicable in their own jurisdiction before registering and placing bets. 5666b strongly encourages all prospective players to seek independent legal advice if in doubt.
Age Restriction: This platform is strictly for adults aged 21 and above. We enforce age verification during the KYC process and reserve the right to close accounts found to belong to users under 21 years of age.
