How to Read Odds — The basics of betting
Decimal Odds
The most common format in Bangladesh and Europe. Multiply the odds figure by your stake to get the total return.
Example: You place a ৳500 bet at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900
Of that, ৳500 is your original stake and the remaining ৳400 is profit.
Implied Probability
Odds show how likely the bookmaker considers a given outcome to be. Odds of 1.80 imply roughly a 55–56% probability. The lower the odds, the more likely that outcome is — but the smaller the potential return.
Other Formats
Fractional odds (e.g. 4/5) are common in the UK — ৳4 profit for every ৳5 staked. American odds (shown as +150 or -120) are used in the United States. Decimal format is the most convenient on ko77 because the calculation is straightforward.
Cashback & Rebate — Get money back every week

| VIP Level | Weekly Cashback | When Credited |

| Bronze | Up to 0.3% | Every Monday |
| Silver | Up to 0.7% | Every Monday |
| Gold | Up to 1.0% | Every Monday |
Terms & Conditions

- There is no wagering requirement on cashback amounts
- If you move up to a higher VIP level, the new rate applies from the following week
Myths & Facts About Gambling
Learn about some common misconceptions about gaming and what the reality actually is.
Slot machines "become due" — if they haven't paid out for a long time, a big win must be coming
FactEvery spin is controlled by an RNG (Random Number Generator) and is completely independent. The result of a previous spin has no effect on the next spin.
Betting more will win back money you have lost
FactEvery bet operates on its own probability. Trying to recover losses with bigger bets often leads to even greater losses.
Following a specific betting system guarantees profit
FactSystems like Martingale or Fibonacci may seem to work in the short term, but the house edge holds over the long term. No system mathematically guarantees profit.
After a losing streak, the next bet is more likely to win (the "cold streak" will end)
FactEvery outcome is independent. Ten previous losses do not increase the probability of the next result at all — this is known as the "gambler's fallacy."
Online casinos always cheat
FactOn reliable platforms, the RNG is certified and fair play is ensured. ko77 follows SSL encryption and a fair play policy.
If a team is "in form," they are bound to win their next match
FactForm is a relevant piece of information, but many variables come into play in a single match. Statistics and analysis help inform decisions — they do not guarantee outcomes.
Play on Mobile — Anytime, anywhere
ko77 is fully browser-based — it runs smoothly on any smartphone, whether Android or iPhone. No separate app download is needed and it uses less data. You can place bets even while sitting in Dhaka traffic.
Add a shortcut to your home screen
Open ko77.bar in Chrome or Safari.
Tap the browser menu or share button.
Select "Add to Home screen" — that's it!
Mobile security tips
- Use a stable connection — to avoid page reloads during live games.
- Keep your browser updated — for both security and performance.
- If you play on a shared phone, log out when you finish.
- Warning: Do not install anything from betting app links found on Telegram or Facebook — these may be fraudulent.
Account Verification Process — Simple & transparent
KYC verification ensures your account is secure and withdrawals are processed quickly. You only need to do it once.
Why is KYC required?
Identity verification to protect your account, prevent fraud, and ensure financial security is an internationally accepted standard.
What documents are needed?
A clear photo of your National ID (NID) or passport. A utility bill or bank statement for address verification.
Selfie Verification
Take a selfie holding your ID card. If the photo is clear and well-lit, the process will be completed faster.
After Verification
Once verified, your withdrawal limit increases and you get access to all payment methods. The process is completed quickly.
After you submit your documents, you will receive a confirmation email once the review is complete. You can deposit before verification is done, but full verification is required for withdrawals.
