Cricket Formats Explained Simply
Before betting, cricket fans in Bangladesh should understand the differences between each format and how the markets vary.
T20
Each team plays a maximum of 20 overs. A match usually finishes in 3 to 4 hours. Match winner, total sixes and top batsman are the most popular markets. BPL, IPL and the T20 World Cup are all played in this format.
ODI (One-Day)
Each team plays 50 overs and a match lasts 7 to 8 hours. Partnership runs, innings wickets and man of the match markets are popular. The ICC Cricket World Cup is played in ODI format.
Test
A five-day match where each team plays two innings. Session betting, series winner and test match draw markets are characteristic of this format.
The Hundred
Each team plays 100 balls in this English tournament. Because matches are short, live betting moves very fast. BBL and PSL are also played in T20 format and are popular among Bangladeshi bettors.

Crash Game — Fast and Exciting
Crash games like Aviator and JetX are currently very popular in Bangladesh. In these games, a plane or rocket takes off and the multiplier keeps rising.
How each round works: place your bet before the game starts, then the multiplier rises as the plane takes off. Cash out at any moment — before the plane crashes. If you wait too long, you may lose your entire bet.
Auto Cash Out
Set a target multiplier and the game will cash out automatically once it is reached.
Set a Stop Limit
Set a loss limit before you start playing — once you hit it, take a break.
Remember: There is no guaranteed strategy or signal for winning at crash games. Stay away from any service that claims to offer "predictions" or "signals".
How to Read Odds
Understanding betting odds is one of the most important skills for any new player. 5666d uses the decimal format, which is the easiest to understand.
Decimal Odds Example
You placed a bet of ৳500 at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900
Profit = ৳900 - ৳500 = ৳400
Implied Probability
Formula: 1 ÷ Odds × 100%
Example: 1 ÷ 1.80 × 100 = approximately 55.6%
This means the bookmaker assumes this team wins about 55.6% of the time.
Comparison of Three Odds Formats
| Format | Example | Where Used |
|---|---|---|
| Decimal | 1.80 | Europe, Bangladesh |
| Fractional | 4/5 | UK, Ireland |
| American | -125 | United States |
All odds on 5666d are displayed in decimal format. The lower the odds, the more likely the bookmaker considers that outcome to be.
Account Verification Process
KYC (Know Your Customer) or account verification is for your security — it prevents account theft and fraud, and ensures your withdrawals are processed.
National ID Card
Upload clear photos of the front and back of your NID.
Proof of Address
A utility bill or bank statement (within the last 3 months) is accepted.
Selfie Verification
A clear selfie holding your NID is required.
Processing Time
Verification is usually completed within 1 to 24 hours.
Once verification is complete, you will receive a confirmation email and all withdrawal limits will return to normal.
