KYC (Know Your Customer) verification protects both you and ko77. It ensures your funds are secure and withdrawals processed smoothly. Here is what to expect at each stage.
Register Your Account
Create a ko77 account with a valid mobile number or email address. Use a number accessible via bKash or Nagad for the smoothest experience.
Submit Your National ID
Upload a clear photo of your Bangladesh National ID (NID) card — front and back. Ensure all four corners are visible and the text is legible.
Provide Address Proof
A recent utility bill, bank statement, or official document showing your current address in Dhaka, Chittagong, Sylhet, or elsewhere in Bangladesh is accepted.

Take a live selfie holding your NID. This step confirms you are the account owner and prevents unauthorized access to your winnings.

Cricket Formats Explained
Understanding cricket formats helps you make smarter bets on ko77. Each format has unique over counts, match durations, and betting market dynamics worth knowing before you wager.
T20 — Twenty20
20 overs per side, completed in roughly 3 hours. The fastest format and most popular for live betting — dynamic odds shift with every ball. BPL and IPL are the headline T20 leagues for Bangladesh bettors.
ODI — One Day International
50 overs per side, lasting 6-8 hours. Betting markets include match winner, top batsman, total runs, and over/under lines. Bangladesh Tigers have strong ODI form — an ideal market for local bettors.
Test Cricket
Up to 5 days of play across two innings per side. The purest form of cricket rewards patience — session betting (morning, afternoon, evening) and series winner markets are most popular in Test wagering.
The Hundred
100 balls per side, each bowler limited to 10 consecutive or 5+5 delivery sets. Fast-paced and beginner-friendly — great entry point for new bettors interested in English domestic cricket.

Betting Glossary
RTP (Return to Player)
The percentage of total wagered money a slot or casino game pays back to players over time. A 96% RTP means ৳96 returned for every ৳100 wagered on average.
House Edge
The mathematical advantage the casino holds over the player in any given game. For example, European Roulette carries a 2.7% house edge — lower than American Roulette at 5.26%.
Wager / Stake
The amount of money you place on a single bet or spin. Managing your stake per round relative to your total bankroll is the foundation of responsible gambling.
Odds
A numerical expression of the probability of an outcome and the potential payout. Decimal odds of 2.50 mean you receive ৳2.50 for every ৳1 wagered, including your original stake.
Parlay / Accumulator
A single bet combining two or more selections where all must win for a payout. Higher risk but significantly higher potential returns — popular for cricket multi-match betting.
Live Bet
A bet placed on an event that is already in progress. Odds update in real time based on the current game situation — ko77 offers live betting on cricket, football, and kabaddi.
Cash Out
A feature that lets you settle a bet before the event ends, locking in a partial win or cutting a potential loss. Available on selected live markets at ko77.
Bankroll
The total funds you have set aside specifically for gambling. Sound bankroll management — betting no more than 1-5% per session — extends your playtime and reduces risk.
Volatility
Describes how frequently and how large a slot pays out. Low-volatility slots pay small wins often; high-volatility slots pay larger wins less frequently. Choose based on your session budget.
Wagering Requirement
The number of times you must bet a bonus amount before withdrawing associated winnings. A 30x wagering requirement on a ৳1,000 bonus means you must wager ৳30,000 in total before cashing out.
