bdspin Keno Bonus Number — Complete Player Guide
Discover how the Keno Bonus Number game works at bdspin, learn proven number-selection strategies, understand payout structures, and find out how to get the most from every draw.
What Is Keno Bonus Number
Keno Bonus Number is one of the most relaxed and accessible lottery-style games available on bdspin. If you have never played Keno before, here is everything you need to know before your first draw.
Keno is a draw-based number game with roots stretching back centuries. On bdspin, the Keno Bonus Number variant gives the classic format an extra layer of excitement: alongside the standard draw, one specially designated Bonus Number is revealed at the end of each round. Matching the Bonus Number — whether or not it was on your original selection — triggers an enhanced multiplier on your winnings, and in some rounds, an outright jackpot-style prize.
The appeal of Keno Bonus Number across Bangladesh is easy to understand. Players in Dhaka, Chittagong, Sylhet, and Khulna are drawn to it for the same reasons they enjoy traditional lottery draws — the suspense of watching numbers appear one by one — but with the added benefit of being able to play instantly from a mobile browser using bKash or Nagad, without queuing at a physical outlet.
Unlike cricket betting, where form analysis and match-day conditions play a large role, Keno is a pure-chance game powered by a certified Random Number Generator (RNG). Every draw is completely independent of the one before it, meaning no sequence of past results can predict future outcomes. The fairness of the RNG is independently audited, so every player starts each round on equal footing.
Number Pool
Numbers 1 through 80 are available in each draw. You select between 1 and 10 numbers (called a "spot" game) before the draw begins.
Bonus Number
After the standard 20 drawn numbers, one additional Bonus Number is revealed. Matching it adds a multiplier on top of your base payout.
Round Speed
Each Keno Bonus Number round completes in approximately 3–4 minutes, meaning you can play 15 or more rounds in an hour at your own pace.
Minimum Stake
Keno Bonus Number on bdspin starts from as low as ৳10 per round, making it accessible for casual players and students across Bangladesh.
Quick Fact: The name "Keno" is believed to derive from the French word quine, meaning "five winning numbers". The modern lottery-style version became popular in 19th-century America before spreading globally. On bdspin, the Bonus Number variant is the most-played Keno format among Bangladeshi players.
How to Play Keno Bonus Number at bdspin
Getting started with Keno Bonus Number on bdspin takes less than a minute. Here is the full step-by-step process from account login to receiving your payout.
Log In to Your bdspin Account
Visit bdspin and sign in with your registered mobile number and password. If you are new, registration takes under two minutes — you will need a valid Bangladeshi mobile number. Make sure your account balance is funded via bKash, Nagad, Rocket, or Upay before you start.
Navigate to Keno Bonus Number
From the bdspin Casino lobby, find the Keno section. Keno Bonus Number is listed prominently as one of the most popular lottery-style games. Click or tap the game thumbnail to open the game interface.
Set Your Stake Amount
Use the stake selector to choose how much you want to wager on this round. Stakes range from ৳10 to ৳10,000 per round depending on your account tier. Your total potential payout scales proportionally with your stake.
Select Your Numbers (1–10 Spots)
Click on between 1 and 10 numbers from the 80-number grid. Your selections are highlighted in gold. You can also use the Quick Pick feature to let the system choose randomly — a popular option among players in Sylhet and Rajshahi who prefer a faster experience.
Confirm and Watch the Draw
Once you confirm your bet, the draw begins. Twenty numbers are drawn from the pool of 80, displayed one at a time. Matched numbers on your card light up in gold. After the main draw, the special Bonus Number is revealed with a distinct animation.
Collect Your Winnings
If you have matched enough numbers — and especially if the Bonus Number was among your picks — your winnings are credited to your bdspin balance instantly. You can withdraw to bKash or Nagad at any time once your balance meets the minimum withdrawal threshold.

The Bonus Number Explained
The Bonus Number is what separates Keno Bonus Number from the standard Keno game. Understanding exactly how it works is key to appreciating your true payout potential.
At the end of each Keno Bonus Number draw on bdspin, after the standard 20 numbers have been revealed, the game draws one additional number from the remaining pool — this is the Bonus Number. It is displayed with a distinct golden glow and separate animation so there is no confusion about which ball it is.
The Bonus Number works in two ways depending on whether it matches one of your selections:
- Bonus Number matches one of your picks: Your base payout for that round is multiplied by the active Bonus Multiplier, which varies between rounds. Multipliers typically range from 2× to 10×, with rare special draws offering up to 20×.
- Bonus Number does not match your picks: Your payout is calculated on standard matched numbers only — the Bonus Number has no negative impact. You simply do not receive the bonus multiplier for that round.
- Bonus Number as a standalone feature: In some bdspin Keno Bonus Number variants, the Bonus Number also independently pays out a small fixed prize even if it does not match your main picks — check the specific game rules for the variant you are playing.
Key Insight
The Bonus Number is drawn from the numbers NOT already selected in the main draw of 20. This means there are always 60 possible Bonus Number candidates, giving a clear 1-in-60 base probability for any specific number to be selected as the Bonus Number.
You pick 5 numbers: 3, 12, 25, 37, 49. The main draw hits 3, 12, and 25 (3 matches). Your standard payout for a 5-spot, 3-match on a ৳100 stake might be ৳300.
Payout Structure & Odds
Keno payouts grow rapidly as you match more of your selected numbers. The table below shows typical payout multipliers for a 10-spot game (picking 10 numbers from 80). All values shown as multiples of your stake. Actual in-game values may vary.
| Numbers Picked | Numbers Matched | Base Payout (× Stake) | With Bonus Number | Notes |
|---|---|---|---|---|
| 10 | 0 | 0× | 0× | No match — no payout |
| 10 | 1 | 0× | 0.5× | Bonus Number match only triggers a partial return |
| 10 | 2 | 0× | 1× | Stake returned when Bonus matched |
| 10 | 3 | 1× | 2× | Bonus Active |
| 10 | 4 | 2× | 5× | Bonus Active |
| 10 | 5 | 10× | 25× | Bonus Active |
| 10 | 6 | 50× | 100× | Bonus Active |
| 10 | 7 | 200× | 400× | Bonus Active |
| 10 | 8 | 1,000× | 2,500× | Bonus Active |
| 10 | 9 | 5,000× | 10,000× | Near Jackpot |
| 10 | 10 | 10,000× | 25,000× | Maximum Prize |
Understanding the Odds
In a standard 10-spot Keno game with 20 draws from 80 numbers, the probability of matching all 10 numbers is astronomically small — roughly 1 in 8.9 billion. However, matching 5 or 6 numbers is genuinely achievable and happens regularly across bdspin's player base. The Bonus Number feature makes mid-tier wins significantly more valuable.
House Edge & RTP
Keno Bonus Number on bdspin carries an RTP (Return to Player) in the range of 92%–95% depending on the specific variant and the number of spots chosen. This is broadly in line with the industry standard for certified Keno products. Fewer spots chosen (e.g., 4-spot or 5-spot games) tend to carry slightly better RTPs than 10-spot games.
Payout multiples shown are indicative. Always check the in-game paytable before placing a wager. Payouts may differ between Keno Bonus Number variants available in the bdspin Casino lobby.
Number Selection Strategy
Keno is a game of chance — no strategy can predict which numbers will be drawn. However, the way you structure your bets, manage your bankroll, and choose your spot size can meaningfully affect how long you play and how much variance you experience.
Choose the Right Spot Size for Your Goal
The number of spots you select is the single biggest strategic decision in Keno. Fewer spots (3–5) give you a higher hit rate with smaller individual payouts — good for extended play on a limited budget. More spots (8–10) offer massive top prizes but a much lower chance of matching enough numbers to win anything. For recreational players in Bangladesh depositing ৳500–৳2,000, a 5-spot or 6-spot game offers a solid balance between frequency and reward.
Do Not Chase "Hot" or "Cold" Numbers
Every Keno draw is independent. A number that appeared in the last five consecutive draws is not "hot" in any meaningful statistical sense — its probability of appearing in the next draw is exactly the same as any other number. Similarly, a number that has not appeared for many rounds is not "overdue". The RNG has no memory. Basing your picks on perceived patterns is a cognitive bias, not a strategy.
Spread Your Numbers Across the Grid
While this does not change your mathematical odds, many experienced Keno players find that spreading picks evenly across the grid (low numbers 1–20, mid-range 21–60, higher numbers 61–80) leads to a more consistent match rate per session compared to clustering picks in a small range. This is a personal preference, not a mathematical advantage.
Keep Your Stake Proportional to Your Session Budget
With rounds completing every few minutes on bdspin, it is easy to go through your session budget quickly if each stake is too high. A general rule: keep each round stake at no more than 2%–5% of your total session budget. If your session budget is ৳1,000, each round stake should be between ৳20 and ৳50. This gives you at least 20 rounds of play and ensures variance does not wipe you out in a single unlucky sequence.
Maximise Bonus Number Exposure
Since the Bonus Number is drawn from the 60 numbers NOT in the main draw, your picks have a direct chance of being the Bonus Number — but only if they were not already drawn in the main 20. This means picking numbers across a wider range slightly increases the statistical chance that at least one of your picks ends up as the Bonus Number rather than a standard draw match. Keeping 1–2 of your picks in the higher number range (60–80) where draws are naturally less frequent can help here.
Set a Win Goal and a Stop-Loss Before You Start
Decide before your session begins: if you double your session budget, you stop and pocket the profits. If you lose 70% of your session budget, you stop and come back another day. These self-imposed rules protect you from the natural psychological pull of chasing losses or getting greedy after a good win. Write them down. Stick to them. This is the most effective "strategy" in any casino game — and it applies equally to Keno Bonus Number players in Dhaka, Chittagong, and anywhere else in Bangladesh.
Spot Size Comparison
| Spots | Variance | Max Payout | Best For |
|---|---|---|---|
| 1–3 | Low | ~15× | Beginners |
| 4–6 | Medium | ~1,500× | Casual play |
| 7–8 | High | ~10,000× | Thrill seekers |
| 9–10 | Very High | ~25,000× | Jackpot hunters |
Quick Strategy Checklist
- Set a session budget before opening the game
- Choose 5–6 spots for balanced risk/reward
- Spread picks across low, mid, and high numbers
- Never increase stakes to chase losses
- Use Quick Pick occasionally to avoid number bias
- Take breaks every 30–45 minutes
- Stop playing when your win goal or stop-loss is hit
