Card GamesPoker, Teen PattiMany people in Bangladesh first hear about BK99 as an “earning app” — a friend shares a referral link and promises easy Taka. This review looks past that promise. We explain what the BK99 app actually is, how its bonuses and referral rewards work, how to install the APK, and what to check before you deposit or try to withdraw.
At a glance: BK99 APK v3.9 · about 25 MB · Android 6.0 or newer · payments listed: mobile banking, Nagad, Rocket and bank transfer.
What Is BK99, Really?
It is a real-money gaming platform with casino-style games, run through an Android app and a mobile website. Money you win or lose comes from the games themselves; the “earning” side people talk about is mostly promotions — welcome offers, cashback, free spins and rewards for inviting friends.
That difference matters. Promotions can add value, but they are not a salary. Every bonus comes with conditions, and nobody can promise you a steady income from a betting app.

How the “Earning” Features Work
Welcome Offer
New accounts can usually claim a first-deposit bonus. The bonus money is locked until you meet a wagering requirement — for example, betting the bonus a set number of times. Until then it cannot be withdrawn.
Cashback
Cashback returns a small share of losses over a period. It softens a bad week; it does not turn losses into profit.
Free Spins
Free spins are tied to specific slot games, and winnings from them are often treated as bonus money with their own rules.
Referral Rewards
Invite a friend and you may receive a reward when they sign up or deposit. Be honest with friends: they are signing up for a gambling platform, not a job.
How to Download and Install the BK99 APK
- Open the app’s official site in Chrome on your Android phone.
- Tap the APK download button and wait for the roughly 25 MB file.
- Allow Chrome to install unknown apps when Android asks.
- Install, open the app, then switch that permission off again.
For general advice on keeping your phone and apps safe, see Android’s official security and privacy guide.
Your phone needs Android 6.0 or newer. If the installer says “App not installed”, free up some storage, delete any older copy, and try again.
Registering a BK99 Account
- Tap Register and enter your mobile number.
- Choose a strong password and verify the number with the SMS code.
- If a friend invited you, enter their referral code now — it usually cannot be added later.
- Complete your profile with your real name and confirm you are 18+.
Deposits and Withdrawals
The cashier lists mobile banking, Nagad, Rocket and bank transfer. A few rules save a lot of trouble:
- Withdraw to a wallet in your own name — the same one you deposited from.
- If you accepted a bonus, finish its wagering before requesting a withdrawal, or the request may be refused.
- The first cash-out may need identity checks, so register with true details.
- Note the limits and processing time shown in the cashier; they can change.
Start with a small deposit and a small withdrawal. A platform that pays out a small amount smoothly is easier to trust with more.

Only adults 18+ should use the app. Never share your OTP, set a monthly limit, and stop if you start chasing losses. Our Responsible Gambling page explains the warning signs. Free, confidential help is also available from Gambling Therapy.
Conclusion
The app is a casino-style app with a busy promotions page and familiar Bangladeshi payment options. Enjoy it as entertainment, read every bonus rule before you accept it, and treat referral “earnings” as a small extra, not an income.
