What Is Keno Bonus Number?
A fast-paced number draw game that blends lottery-style excitement with the instant gratification of online casino play.
Keno Bonus Number is one of the most popular draw-based games available at okbt, and it has found a particularly enthusiastic following among players in Dhaka, Chittagong, and Sylhet who enjoy the combination of simplicity and big-win potential. The game traces its roots to ancient Chinese lottery traditions, but the online version at okbt has been refined into a sleek, mobile-first experience that fits naturally into everyday life in Bangladesh.
The core mechanic is straightforward: a grid of numbers from 1 to 80 is presented to you, and you choose between 1 and 10 numbers — called "spots" — that you think will be drawn. The game's Random Number Generator (RNG) then selects 20 numbers from the 80 available. The more of your chosen spots that match the drawn numbers, the higher your payout. A special Bonus Number is also drawn each round, and if it lands on one of your selected spots, your winnings receive a significant multiplier boost.
What makes the okbt version particularly appealing is the Bonus Number mechanic, which adds a second layer of excitement on top of the base game. In a standard keno game, the result is simply a count of matched numbers. At okbt, the highlighted Bonus Number — drawn separately after the main 20 numbers — can transform a modest win into a life-changing payout, making every draw feel significant right up until the last ball.

Understanding the paytable before you play is one of the smartest things you can do. All multipliers below are based on a single ৳100 stake.
| Spots Picked | Numbers Matched | Base Payout | With Bonus Number |
|---|---|---|---|
| 1 Spot | 1 of 1 | ৳300 | ৳600 |
| 2 Spots | 2 of 2 | ৳900 | ৳1,800 |
| 3 Spots | 3 of 3 | ৳2,500 | ৳5,000 |
| 4 Spots | 4 of 4 | ৳7,200 | ৳14,400 |
| 5 Spots | 5 of 5 | ৳18,000 | ৳36,000 |

RTP & House Edge
Keno Bonus Number at okbt carries a certified RTP of approximately 95.5% on standard play. When the Bonus Number multiplier is active, the effective RTP for that round rises to around 96.2%. The house edge of around 4.5% is competitive for the draw-game category and lower than most land-based lottery products available in the Bangladesh market.
Odds at a Glance
The probability of matching all 10 spots on a 10-pick ticket is approximately 1 in 8.9 million — rare, but the reason the jackpot is so large. Matching 5 of 5 occurs roughly once every 1,550 tickets. Most experienced players at okbt prefer 4- or 5-spot tickets for a balance of hit frequency and payout size, treating the Bonus Number as a free boost when it lands.
Bonus Number Feature Explained
The feature that makes okbt's version stand apart from standard keno — and why players keep coming back for the next draw.
After the main 20 numbers are drawn and your matches are counted, the game reveals one final number: the Bonus Number. This ball is drawn from the remaining 60 numbers that were not selected in the main draw, so it is guaranteed to be a fresh number and not a repeat. If any one of your selected spots equals the Bonus Number, your entire round payout is doubled.
The Bonus Number mechanic works on all ticket types — whether you picked 1 spot or all 10. This means even a low-spot ticket that scored a modest win can instantly double in value, and a near-miss ticket that matched most of its spots suddenly becomes a significant payout event.
During Eid and Pohela Boishakh seasonal promotions at okbt, the Bonus Number multiplier is temporarily increased from 2x to 3x for a limited promotional window. These promotion periods are announced in advance on the okbt promotions page, and players in Dhaka, Rajshahi, and Khulna have historically seen the highest engagement during these festive draw events.
During special promotions, okbt may introduce a Double Bonus Draw — where two Bonus Numbers are revealed instead of one. If either matches your selection, the 2x multiplier applies. Watch the okbt promotions section for upcoming double-draw events.
How the Bonus Number Is Drawn
- Main draw completes — 20 numbers from 1–80 are selected by the RNG.
- Your matched spots are highlighted and a base payout is calculated.
- The Bonus Number is drawn from the 60 remaining (undrawn) numbers.
- If the Bonus Number matches any of your original spot selections, the base payout is multiplied by 2x.
- Final winnings are credited to your okbt wallet immediately after the result is confirmed.
Standard Multiplier
2x your base round payout when the Bonus Number matches one of your selected spots.
Festive Multiplier
Up to 3x during okbt seasonal promos (Eid, Pohela Boishakh, Victory Day special events).
Strategy Tips for Bangladeshi Players
Keno is a game of chance, but smarter choices around spot selection and bankroll use can make your sessions more enjoyable and your budget last longer.
Choose 4–6 Spots for Balance
Picking 4 to 6 spots gives you a reasonable hit frequency while still offering meaningful payouts. Very low spot counts (1–2) pay modestly on a match, while 9–10 spots rarely hit all numbers. The 4-6 range is the sweet spot most regular okbt players gravitate toward after a few sessions.
Session Bankroll Discipline
Before each session, decide on a fixed budget — say ৳2,000 — and split it into equal bets of ৳50 or ৳100 per round. This gives you 20–40 draws, enough to experience natural variance without burning through your balance in the first few minutes. Never chase losses by increasing your stake mid-session.
Avoid Hot-Number Fallacy
Each Keno draw at okbt is generated by a certified RNG, which means every number from 1 to 80 has an equal probability of being drawn on every single round, regardless of what appeared in previous draws. There are no "hot" or "cold" numbers — the draw has no memory. Choosing numbers based on past results does not improve your odds.
Use Your Welcome Bonus on Keno
okbt's welcome bonus — up to ৳20,000 on your first deposit — can be wagered on Keno Bonus Number. Check the wagering contribution rate for keno (typically 10–30% of each bet counts toward the playthrough requirement) before you start. Playing with bonus funds on Keno is a low-pressure way to explore the game before committing real money.
Play During Off-Peak Hours
Server load at okbt is highest in the evening between 8 PM and 11 PM Bangladesh Standard Time (BST, UTC+6), especially during BPL season when the sportsbook and casino lobby are both busy. If you prefer smoother game animations and faster result rendering, early morning sessions (6 AM–9 AM BST) tend to be more responsive.
Target the Bonus Number Deliberately
Some experienced players select numbers that they believe are positioned to maximise the Bonus Number impact — for example, spreading selections evenly across the 1–80 range rather than clustering them together. While this does not change the statistical probability, a wider spread means your selected numbers cover more of the pool the Bonus Number is drawn from.
18+ Responsible Gaming Reminder. Keno Bonus Number is a game of chance. No strategy guarantees a win. Set deposit and loss limits in your okbt account settings before you start playing, and treat every session as entertainment, not income. If gambling stops being fun, use the self-exclusion tool or visit our Responsible Gaming page for free tools and support resources.

Does the okbt welcome bonus apply to Keno Bonus Number?

How is the Bonus Number different from the main 20 drawn numbers?
The 20 main numbers are drawn first from the full pool of 1–80.
