Number Games
Keno Bonus Number on basa.8 takes the classic number-picking game and adds a twist that changes everything — a dedicated Bonus Number drawn each round that multiplies your winnings when it lands in your selection. Fast draws, flexible picks, and payouts straight to bKash or Nagad.
Game Overview
Keno is one of the oldest lottery-style games in the world, and Keno Bonus Number on basa.8 is the modern version built for fast online play. The setup is straightforward — there are 80 numbers in the pool, and each round the game draws 20 of them. You pick between 1 and 10 numbers before the draw, and you win based on how many of your picks match the drawn numbers.
The Bonus Number is what separates this version from standard keno. At the start of each round, one number from the pool is designated as the Bonus Number. If that number appears in your selection and it gets drawn, your payout for that round is multiplied. The multiplier value changes each round, which keeps things interesting even when you're playing the same pick size every time.
On basa.8, the draws happen quickly — typically every 3 to 5 minutes — so there's no long wait between rounds. You can adjust your picks and bet size between draws, or keep the same selection running on repeat using the Quick Pick or Favourite Numbers feature.
A standard keno win on a 5-pick selection pays at a fixed rate. Hit the Bonus Number in that same selection and the payout can jump by 2× to 10× depending on the round multiplier. Over a session, catching the Bonus Number even once or twice can completely change your results.

One special number per round that multiplies your payout when it hits.
Number Grid
Every round, 20 numbers are drawn from the full pool of 1–80. The highlighted balls below show a sample draw — gold balls are matched picks, blue is the Bonus Number, and green shows a matched Bonus Number hit.
In this sample, 8 numbers were selected. 5 matched the draw, and the Bonus Number (37) was in the selection and drawn — triggering the multiplier.
Sample display only. Actual drawn numbers are determined by a certified RNG each round.
Bonus Feature
Each round in Keno Bonus Number on basa.8 comes with a randomly assigned multiplier value. If the Bonus Number lands in your selection and gets drawn, your entire round payout is multiplied by that value.
Most common multiplier. Doubles your round payout instantly.
Triples the payout. Appears regularly across sessions.
Less frequent but a significant boost when it hits.
Rare multiplier that can turn a modest win into a big one.
The top multiplier. Catching this with a full match is the best outcome in the game.
The Bonus Number multiplier is applied to your total payout for that round — not just the payout from the Bonus Number itself. So if you matched 6 out of 8 picks and the Bonus Number was one of those 6, the entire 6-match payout gets multiplied. That's what makes catching the Bonus Number so impactful on basa.8.

Smaller pick sizes (Pick 1–3) have lower variance — you win less but more often. Larger pick sizes (Pick 8–10) are higher variance — wins are rarer but the payouts, especially with a Bonus Number multiplier, can be substantial. Choose your pick size based on your session budget and how much swing you're comfortable with.

Probability Guide
Keno odds are fixed by the pool size and draw size. Here's a quick breakdown of match probabilities for common pick sizes on basa.8.
The Bonus Number is one of the 80 numbers in the pool. If you're playing Pick 5, the chance that the Bonus Number falls within your 5 picks is 5/80 = 6.25%. If it does land in your selection, the chance it gets drawn is 20/80 = 25%. So the combined probability of triggering the Bonus multiplier on a Pick 5 ticket is roughly 1.56% per round — not common, but it happens regularly over a session.
The more numbers you pick, the higher the chance the Bonus Number falls within your selection. On a Pick 10 ticket, the probability of the Bonus Number being in your picks is 10/80 = 12.5% — double that of a Pick 5. This is one reason many basa.8 players prefer larger pick sizes when chasing the multiplier.
Strategy Guide
Keno is a game of chance — no strategy changes the underlying odds. But how you structure your sessions on basa.8 can affect how long you play and how you experience variance.
Switching pick sizes every round makes it harder to track your results and understand the payout structure. Pick a size that matches your risk preference and stick with it for the session. This also makes it easier to set a sensible bet size relative to your budget.
You don't know which number will be the Bonus Number before you pick, so you can't target it directly. However, spreading your picks across different sections of the 80-number grid gives you a statistically even chance of the Bonus Number landing in your selection regardless of which number is chosen.
Decide how much you're comfortable spending per round before you start. With rounds running every few minutes on basa.8, it's easy to play more rounds than planned. A fixed per-round budget keeps your total session spend predictable regardless of how long you play.
If you're using the auto-play feature on basa.8, always set a loss limit. Auto-play is convenient but it removes the natural pause between rounds where you'd normally reassess. A loss limit ensures the feature stops before you've spent more than you intended.
Pick 1 and Pick 3 have lower variance — you'll win smaller amounts more frequently. If your goal is to play for an extended period without large swings, smaller pick sizes give you more rounds per budget. Pick 8–10 is better suited to shorter, higher-stakes sessions.
basa.8 displays recent round results including the Bonus Number and multiplier value for each draw. While past multipliers don't predict future ones, reviewing the history gives you a sense of how frequently high multipliers (5× and above) have appeared in recent rounds.
In Depth
If you've played keno before — whether at a physical lottery counter or on another online platform — Keno Bonus Number on basa.8 will feel immediately familiar. The core mechanics haven't changed: you pick numbers, the game draws numbers, and you get paid based on how many match. What basa.8 has done is take that familiar structure and add the Bonus Number layer on top, which gives every round a secondary outcome to watch for beyond just your match count.
The pace of the game is one of the things players notice first. Rounds on basa.8 run every 3 to 5 minutes, which is significantly faster than traditional lottery-style keno where you might wait 10 to 20 minutes between draws. That faster pace means more decisions per hour, but it also means your budget can move quickly if you're not paying attention to your per-round stake.
The interface on basa.8 is clean and easy to navigate. The 80-number grid is displayed clearly, your selected numbers are highlighted, and the Bonus Number for the upcoming round is shown prominently before the draw starts. As numbers are drawn, they light up on the grid in real time. Matched numbers in your selection are highlighted differently from non-matched drawn numbers, so you can follow the draw without confusion.
Not everyone wants to manually select numbers every round. basa.8 offers two shortcuts. Quick Pick generates a random selection of the size you've chosen — useful when you don't have a preference and just want to get into the next round quickly. Favourite Numbers lets you save a specific set of picks and reload them with one tap, which is handy if you have numbers you like to play consistently.
Neither of these features changes your odds — the draw is random regardless of how your numbers were chosen. But they do make the experience smoother, especially when you're playing multiple rounds in a session.
One of the practical advantages of playing Keno Bonus Number on basa.8 is the payment setup. The platform supports bKash, Nagad, and Rocket — the three most widely used mobile financial services in Bangladesh. Deposits are processed instantly with a minimum of ৳200. Withdrawals go back to the same mobile wallet and are typically completed within 15 minutes for verified accounts.
There are no fees charged by basa.8 on standard deposits or withdrawals. Your mobile wallet provider may apply their own transaction charges depending on your account type, but basa.8 does not add any platform-side fees on top of that.
Keno Bonus Number is fully playable on mobile browsers without any download. The number grid scales correctly to smaller screens, and the tap targets are large enough to select numbers accurately on a phone display. The basa.8 app provides a slightly more optimised experience with faster load times, but the browser version works well on both Android and iOS.
Auto-play is available on mobile as well. You can set up a run of rounds, lock your screen, and check back when the session is complete. The app will notify you if your win cap or loss limit is reached.
Keno Bonus Number is a fast-paced game and it's easy to play more rounds than you planned. basa.8 provides deposit limits, session time reminders, and self-exclusion tools in your account settings. If you feel your play is becoming difficult to control, use these tools or visit the Responsible Gaming page for guidance. Gambling should be entertainment, not a financial strategy.
