Cricket Formats Explained
Understanding the format you are betting on is the first step to smarter cricket wagering. Here is a quick breakdown of every major format.
T20 (Twenty20)
20 overs per side, typically completed in 3–4 hours. The fastest format drives the highest betting volume, with markets on every over and wicket. Key leagues: BPL, IPL, T20 World Cup, BBL, PSL.
ODI (One Day International)
50 overs per side, typically 7–8 hours. A richer variety of betting markets including top run-scorer, total sixes, and innings totals. Bangladesh Tigers regularly compete in the ICC ODI World Cup.
Test Cricket
Up to 5 days of play, 2 innings per side. The purest form of the game offers unique long-form betting markets — day-by-day session winners, series scores, and first innings leads.
The Hundred
100 balls per side — a newer format from England. Shorter even than T20, it produces high-scoring games and dynamic in-play betting markets gaining popularity in Bangladesh.
Key Leagues to Follow on 5666tk:
BPL (Bangladesh Premier League) · IPL (Indian Premier League) · T20 World Cup · ICC Cricket World Cup · PSL (Pakistan Super League) · BBL (Big Bash League) · The Hundred · Asia Cup · Bilateral Bangladesh Tigers series

Account Security
Account Verification & KYC Guide
KYC (Know Your Customer) verification protects both you and the platform. Here is exactly what to expect during the process.
Submit Your National ID (NID)
Upload a clear photo or scan of both sides of your Bangladesh National Identity Card. Ensure all text and your photo are fully visible with no obstructions or glare.
Provide Proof of Address
A recent utility bill, bank statement (from BRAC Bank, City Bank, Dutch-Bangla Bank, etc.), or official letter showing your name and current address in Bangladesh, dated within the last 3 months.
Complete Selfie Verification
Take a clear selfie holding your NID card next to your face. This confirms the document belongs to you and prevents identity fraud on your account.
Await Review (1–24 Hours)
Our compliance team reviews submitted documents within 1 to 24 hours during Bangladesh Standard Time (BST, UTC+6) business hours. You will receive an email confirmation once approved.
Full Account Access Unlocked

Responsible Play
Bankroll Management Guide
Smart bankroll management is the single most important skill any gambler can develop. It does not guarantee winnings — but it protects you from unsustainable losses and keeps gambling enjoyable long-term.
- Set a firm monthly gambling budget. Decide in advance how much you can comfortably afford to lose each month. Treat this amount like an entertainment expense — not an investment. Players in Dhaka and Chittagong often find setting a separate bKash wallet for gambling funds helps enforce this boundary.
- Divide your bankroll into session amounts. Split your monthly budget into individual session amounts. For example, a ৳5,000 monthly budget might be divided into ten ৳500 sessions. Once a session amount is spent, close the app and return another day.
- Follow the 1–5% per-bet rule. Never stake more than 1% to 5% of your total session bankroll on a single bet or spin. This rule dramatically extends your playing time and reduces the risk of losing everything in a short streak of bad luck.
- Know when to walk away after wins. Set a win target — for example, doubling your session bankroll — and walk away when you reach it. Chasing bigger wins after a good session is one of the most common ways players give back profits.
- Set a hard stop-loss limit. Decide before each session the maximum loss you will accept. If you hit that number, stop immediately. Do not top up mid-session with additional funds from outside your gambling budget.
- Track your play history. 5666tk provides a full transaction and bet history in your account dashboard. Review it weekly. Patterns in your play history reveal habits — both good and bad — that are otherwise invisible in the moment.
Quick Bankroll Checklist
- ✅ Monthly budget set and ring-fenced
- ✅ Session amounts pre-decided
- ✅ Max bet per spin / per game defined
- ✅ Win target and stop-loss target defined
- ✅ Play history reviewed last week
- ✅ Playing for entertainment, not income

Our Story
About 5666tk
5666tk was founded with a straightforward mission: to build the most player-friendly, secure, and locally relevant online gaming platform in Bangladesh. From our earliest days, we recognised that Bangladeshi players deserved more than a generic international platform with inconvenient payment methods and support teams working in the wrong time zone.
Over the past six years, we have grown from a small cricket betting platform into a full-spectrum gaming destination offering over 2,800 games — including live casino tables powered by Evolution Gaming and Ezugi, a world-class slots library from Pragmatic Play and NetEnt, and one of the deepest cricket betting markets in the region. Every major BPL season, Bangladesh Tigers test series, and T20 World Cup tournament brings tens of thousands of new players to our platform, and we take that trust seriously.
Our commitment to the Bangladeshi community goes beyond games. We invest in localised customer support available in both English and Bengali, seamless integration with bKash, Nagad, Rocket, and Upay for frictionless deposits and withdrawals, and responsible gaming tools that help players stay in control. 5666tk is built for Bangladesh — and we are proud of that.
