Game Overview
What Is Keno Bonus Number?
Keno Bonus Number is an online lottery-style draw game that blends the familiar structure of classic Keno with an exciting twist — one specially designated ball in each draw is marked as the Bonus Number. When any of your chosen numbers matches the Bonus Number, your payout for that hit is multiplied by a predetermined bonus factor, dramatically increasing what would otherwise be a standard win.
At a88bet, Keno Bonus Number is available around the clock and draws take place every few minutes. The game board contains 80 numbered spots. Players select between 1 and 20 numbers from the board before each draw. The game then randomly draws 20 numbers. Your prize depends on how many of your chosen numbers match the drawn numbers — and whether the Bonus Number was one of your picks.
Keno has roots stretching back centuries and remains one of the most accessible gambling formats in the world — requiring no specialist knowledge, no strategy memorisation, and no prior gambling experience. Yet the Bonus Number mechanic at a88bet adds a meaningful strategic layer: do you spread your picks across many numbers to increase the chance of a match, or concentrate on fewer numbers to maximise the probability that your Bonus Number hit delivers a high multiplier payout?
Keno Bonus Number is particularly popular among players in Dhaka, Chittagong, and Sylhet who enjoy the game during quiet evening hours or between BPL cricket innings. The draw cycle is short enough to keep the experience engaging without demanding constant attention the way live card games do.
Step-by-Step
How to Play Keno Bonus Number at a88bet
Playing Keno Bonus Number at a88bet is straightforward. From logging in to watching your first draw complete, the entire process can be done in under three minutes — even on a mobile browser in Rajshahi or Khulna with a basic 4G connection.
Minimum bet: ৳20 per round. Maximum bet varies by table — premium tables allow up to ৳100,000 per draw. All amounts in Bangladeshi Taka (BDT).
Bonus Number Tip: The Bonus Number is designated after your picks are locked — you cannot know in advance which drawn number will carry the bonus multiplier. Every drawn number has an equal chance of being the Bonus Number.
Log In to Your a88bet Account
Visit a88bet and sign in using your registered credentials. New players can create an account in under 2 minutes with a valid Bangladeshi mobile number. The platform works seamlessly on Chrome and Firefox browsers on Android and iOS — no app installation required.
Fund Your Account via bKash or Nagad
Navigate to the Cashier section and choose your preferred deposit method. bKash and Nagad credits typically land in your a88bet wallet within 30 seconds. The minimum deposit to begin playing Keno Bonus Number is ৳200. Rocket, Upay, and bank transfers to Dutch-Bangla Bank, City Bank, and BRAC Bank are also available.
Open the Keno Bonus Number Game
From the a88bet game lobby, locate Keno Bonus Number under the Lottery or Instant Games category. The game interface loads a full 80-number grid. Take a moment to familiarise yourself with the layout — the grid, the chip panel, and the draw countdown timer are the three key elements.
Select Your Numbers (1 to 20)
Tap or click any numbers on the 1–80 grid to select them. You may choose as few as 1 or as many as 20. The payout table adjusts in real time to reflect the odds for your specific pick count. You can also use the Quick Pick option to let the system randomly select numbers on your behalf — popular among players who prefer a quick, intuitive session.
Set Your Stake and Confirm
Use the chip selector at the bottom of the screen to set your wager per round — starting from ৳20. Review your selections and stake amount, then press Confirm before the countdown timer reaches zero. Late confirmations after the cutoff are not accepted for the current draw and roll over to the next one.
Watch the Draw
Twenty numbers are drawn one at a time and displayed on screen. Matched numbers on your ticket light up in red. The Bonus Number is revealed last and shown in gold. If the Bonus Number matches one of your picks, your payout for that particular match is multiplied. The total win amount is calculated and credited to your wallet automatically.
Withdraw to bKash, Nagad, or Bank
When ready to cash out, go to Cashier → Withdrawal. Enter your preferred mobile banking number and withdrawal amount. KYC-verified accounts enjoy the fastest processing — typically 15 minutes to 1 hour for bKash and Nagad. All transactions are encrypted with 256-bit SSL security.
Core Feature
The Bonus Number Explained
The Bonus Number is what separates Keno Bonus Number from standard Keno. Understanding how it works — and how to play around it — is the key to getting the most from every round at a88bet.
In every Keno Bonus Number round at a88bet, one of the 20 drawn numbers is randomly designated as the Bonus Number. This designation happens after all 20 numbers have been drawn — ensuring no draw manipulation is possible and every ball has an equal 1-in-20 chance of being the Bonus Number among the drawn set.
When the Bonus Number matches one of your selected picks, the standard payout for that match tier is multiplied. The multiplier value varies by game variant and session rules — common multipliers range from 2x up to 10x on the standard Bonus Number, with special jackpot-mode variants offering up to 20x. The multiplier is applied on top of your existing match payout, not in replacement of it.
It is important to understand that the Bonus Number only matters if it overlaps with a number you have already selected. If the Bonus Number is drawn but does not appear among your chosen numbers, there is no effect on your payout for that round — it simply contributes to the standard 20-number count. This means players who select more numbers have a higher statistical probability of landing a Bonus Number match in any given round.
Some a88bet Keno Bonus Number variants include a "Super Bonus" mode triggered when a player matches a defined number of picks AND the Bonus Number appears in their selection. Super Bonus mode can unlock a separate prize pool or multiply the entire round payout — not just the individual matching number — making it the most valuable single outcome the game can produce.
Key Bonus Number Facts
- One Bonus Number per draw — selected randomly from the 20 drawn numbers
- Each of the 20 drawn balls has a 5% (1-in-20) chance of being the Bonus Number
- Multiplier only activates if the Bonus Number also matches one of your picks
- Multipliers typically range from 2x to 10x on standard rounds
- Super Bonus mode can multiply the entire round payout in eligible variants

Player Tactics
Number Selection Strategies
Keno is a game of chance — no strategy can change the underlying odds of the draw. What strategy can do is help you manage your pick count, stake size, and session length in a way that suits your risk appetite and bankroll.
The Wide Net Approach (15–20 Picks)
Selecting 15 to 20 numbers maximises the probability of matching drawn numbers and increases the chance that the Bonus Number overlaps with your selections. The trade-off is that individual match payouts at lower tiers are smaller. This approach suits players who prefer frequent small wins and a longer session lifespan over a single large payout. It also maximises Bonus Number hit frequency — with 20 picks, roughly 1 in 4 rounds will see your picks include the Bonus Number.
The Precision Approach (4–7 Picks)
Concentrating on 4 to 7 numbers delivers much higher per-match payouts when hits occur, because the payout tables are steeply scaled in favour of exact matches on a small pick set. A 5/5 match on a 5-pick ticket pays far more than a 5/20 match on a 20-pick ticket. The Bonus Number hit rate is lower, but when it does connect on a near-perfect match, the combined payout can be extraordinary. Popular among experienced players in Dhaka who are comfortable with variance.
The Balanced Approach (8–12 Picks)
A pick count of 8 to 12 is widely considered the sweet spot for Keno Bonus Number. It offers a reasonable match frequency, meaningful mid-tier payouts, and a Bonus Number hit rate of approximately 10–15% per round. The 10-pick game in particular offers the best balance between payout table depth (multiple prize tiers) and realistic hit probability — making it the most popular choice among a88bet players in Chittagong and Sylhet.
Use the Same Numbers Consistently
Because each draw is entirely independent, there is no statistical advantage to changing your numbers between rounds. Many players find it mentally easier to commit to a fixed set of numbers and play them consistently across multiple sessions. This removes the decision fatigue of re-selecting picks every round and lets you focus on bankroll management rather than second-guessing your number choices. Use Quick Pick for variety or stick to personal numbers — mathematically, both approaches yield identical long-term outcomes.
Flat Stake Management
Set a fixed stake per round before your session starts and stick to it regardless of whether you are winning or losing. A common approach for players in Bangladesh is to divide the session budget by 50 — so a ৳5,000 session budget yields ৳100 per round, giving 50 draws of play before the budget is exhausted. This prevents the common trap of increasing stakes after losses in an attempt to recover quickly, which can turn a manageable loss into a damaging one inside just a few draws.
Set a Win Target and Walk Away
Decide before your session the profit amount at which you will stop and withdraw. For example: "If I reach ৳3,000 profit, I withdraw and end the session." Most players who fail to set a win target give back their winnings because the game's pace makes it easy to keep playing through a profitable position. Locking in a win target — especially useful during high-energy periods like Eid or BPL season when excitement is high — ensures you leave the session in profit rather than chasing a bigger peak.
Pick Count Strategy Quick Reference
| Pick Count | Bonus Number Hit Frequency | Payout Style | Best Suited For |
|---|---|---|---|
| 1–3 picks | Very low (~1.25–3.75%) | Rare but very high multiplier | High-risk, high-reward players |
| 4–7 picks | Low (~5–8.75%) | Strong top-tier payouts, fewer win tiers | Experienced variance-tolerant players |
| 8–12 picks | Moderate (~10–15%) | Balanced — multiple prize tiers active | Most players — recommended starting point |
| 13–16 picks | Good (~16–20%) | Frequent small-to-mid wins | Session longevity seekers |
| 17–20 picks | High (~21–25%) | Frequent low wins, lower top-tier odds | Casual players preferring steady action |
