Keno is one of Bangladesh's fastest-growing casino game formats — simple to learn, genuinely exciting, and packed with bonus mechanics that separate pklock's offering from a standard number draw. This page breaks down exactly how the Bonus Number works, how it multiplies your winnings, and the smartest ways to pick your spots.
At its core, Keno is a lottery-style number game played on a board of 80 numbers. Each round, the pklock RNG system draws 20 numbers at random. You — the player — select anywhere from 1 to 15 numbers (called a "spot") before the draw begins. The more of your chosen numbers that match the drawn numbers, the higher your payout according to the paytable for your spot size.
The Keno Bonus Number is pklock's signature twist on the classic format. After the standard 20 numbers are drawn, one additional number — the Bonus Ball — is selected from the remaining 60. If this Bonus Number matches any of the numbers you picked on your ticket, your winnings for that round are multiplied by a factor determined by your current stake level and the size of your spot selection. Multipliers range from 2× at the entry level all the way up to 10,000× for maximum spot players hitting the Bonus Number at peak stake.
This mechanic transforms Keno from a passive draw-watching experience into something far more interactive. Players in Dhaka who monitor their selections in real time often describe the Bonus Number reveal as the most electric moment of any casino session — more so than a standard slot spin, because the suspense builds across a full 3-minute draw cycle. Players across Chittagong, Sylhet, and Rajshahi who discovered pklock's Keno during the BPL off-season now treat it as a daily routine, depositing via bKash and running multiple tickets simultaneously.
It is important to understand that the Bonus Number does not replace or override a losing ticket. If none of your selected numbers appear in the standard 20-draw, a Bonus Number match will still produce a payout — but only at the base rate for a single-number match, multiplied by the bonus factor. The real value of the Bonus Number lies in boosting an already-winning ticket to substantially higher returns.
Follow these six steps every time you play Keno at pklock and you will never be caught off-guard by the Bonus Number mechanic.
Select between 1 and 15 numbers from the 80-number board. Your spot size determines the paytable you will be paid from — larger spots carry higher risk but also much bigger potential returns, especially when the Bonus Number activates.
Choose your wager per draw. At pklock, minimum stakes start from ৳10 per ticket, with a maximum of ৳50,000 per round. Higher stakes unlock larger Bonus Number multiplier tiers — the ৳1,000+ bracket activates the premium 500× and 10,000× bonus bands.
The RNG reveals 20 numbers one at a time over approximately 90 seconds. Matching numbers on your ticket light up in yellow. Your provisional winnings are calculated from the standard paytable at this point.
After the 20th standard number, the Bonus Draw begins. One number is pulled from the remaining 60. If it matches any of your originally selected numbers, the Bonus Number multiplier is applied to your total round payout.
The multiplier depends on your stake tier and spot size. A 10-spot player at ৳500 stake who hits the Bonus Number on top of 6 standard matches could see a payout leap from ৳3,000 to ৳45,000 in a single reveal moment.
All Keno winnings — including Bonus Number multiplied amounts — are credited to your pklock wallet instantly at round close. Withdrawals to bKash and Nagad typically clear within 5–15 minutes from there.
The table below shows representative payouts for selected spot sizes. All figures are multipliers of your base stake. Bonus Number column shows the additional multiplier applied when the Bonus Ball matches one of your picks.
| Spot Size | Matches Required | Base Multiplier | With Bonus Number | Max Payout (৳500 stake) |
|---|---|---|---|---|
| 1-Spot | 1 of 1 | 3.5× | 7× | ৳3,500 |
| 2-Spot | 2 of 2 | 12× | 25× | ৳12,500 |
| 4-Spot | 4 of 4 | 72× | 150× | ৳75,000 |
| 5-Spot | 5 of 5 | 410× | 820× | ৳410,000 |
| 7-Spot | 7 of 7 | 1,650× | 3,300× | ৳1,650,000 |
| 10-Spot | 10 of 10 | 5,000× | 10,000× | ৳5,000,000 |
| 15-Spot | 15 of 15 | 10,000× | 10,000× | ৳5,000,000 |

Beyond the welcome bonus, pklock's loyalty programme credits 1 point per ৳100 wagered on Keno. Silver and Gold tier members receive dedicated reload bonuses every Monday morning — typically a 30% match on deposits made over the weekend. Gold VIP members additionally gain access to exclusive high-roller Keno tables with elevated stake ceilings of ৳500,000 per round and private draw schedules.
Keno is a game of chance — no strategy eliminates the house edge. But smart decisions around spot size, staking, and bankroll management can meaningfully extend your session and improve your expected value when the Bonus Number falls your way.
New Keno players at pklock tend to find the sweet spot between hit frequency and payout size at 4–6 spot selections. The probability of hitting enough numbers for a meaningful return is realistic, and the Bonus Number multiplier at this range (roughly 75× to 200× for a full match) still delivers exciting wins without requiring perfect 10-spot luck.
pklock's Keno Bonus Number multiplier scales with your stake level. If you are going to play Keno seriously, consider raising your per-ticket stake to at least ৳200 to unlock mid-tier multiplier brackets. Spreading ৳1,000 across ten ৳100 tickets is statistically identical to five ৳200 tickets, but the latter qualifies for better bonus rates.
pklock's Keno platform supports multi-draw mode — you lock in your number selection for up to 100 consecutive draws. This is useful for players who identify a number pattern they want to run consistently. Multi-draw also means you will not miss a draw while depositing via Nagad or navigating the lobby.
Experienced Bangladeshi Keno players at pklock often run two ticket types simultaneously: one conservative 3-spot ticket for steady small returns, and one aggressive 8-spot ticket targeting the Bonus Number jackpot zone. This portfolio approach keeps the session going even when the big ticket misses.
Before loading your bKash deposit into Keno, decide your maximum loss for the session. pklock's responsible gaming tools let you set a daily loss limit directly in your account dashboard. Keno draws every 3 minutes — without a hard ceiling, sessions can escalate quickly, particularly during the excitement of near-miss Bonus Number reveals.
While pklock's RNG is provably fair and draws are not influenced by table occupancy, off-peak hours (01:00–06:00 BST) typically mean faster interface response times and fewer simultaneous transactions competing for instant withdrawal slots. Players in Mymensingh and Rangpur who play late report faster Nagad payout confirmations during these windows.
The pklock casino library includes multiple Keno formats, each with its own draw speed and Bonus Number mechanic. Here is a breakdown of the key variants currently available.
A draw every 60 seconds. Ideal for players who find the standard 3-minute cycle too slow. Bonus Number is included; multipliers are slightly compressed versus the main game to compensate for draw frequency.
The standard 3-minute draw format with the full Bonus Number mechanic and all 15 spot sizes available. This is the flagship variant at pklock and the one referenced throughout this guide.
The Bonus Number in Power Keno is drawn first, before the standard 20 numbers. If your selected number matches the Power Ball, every subsequent standard match pays at 4× the normal rate. High-variance and extremely popular with Gold-tier members.
Play up to 20 unique tickets per draw simultaneously. Each card has its own number selection; a single Bonus Number reveal checks against all active cards at once. One lucky bonus reveal can trigger multipliers across multiple winning tickets in the same round.
Every Keno game at pklock operates on a certified RNG (Random Number Generator) that is independently verified for statistical fairness. The theoretical Return to Player (RTP) for pklock's Classic Keno sits at approximately 95.5% across all spot sizes — meaning for every ৳1,000 wagered in aggregate, players can expect around ৳955 returned over a long run. Individual sessions, of course, deviate significantly from this average.
The Bonus Number mechanic adds a secondary probability layer. In Classic Keno, the Bonus Ball is drawn from the 60 numbers not selected in the main draw, giving it a 1-in-60 chance of matching any specific number you have chosen. For a 10-spot player, the probability that at least one of their 10 picks matches the Bonus Number is approximately 1 − (50/60 × 49/59 × ... for 10 draws) ≈ 14.8% — so roughly 1 in 7 rounds features a Bonus Number activation for a 10-spot ticket. This frequency is deliberately calibrated to feel achievable without making the multiplier mathematically trivial.
Players from Dhaka's tech community who analyse casino mathematics often note that pklock's Keno Bonus Number mechanic has a higher expected contribution to overall session EV than the base game RTP alone suggests — because the multiplier is applied post-draw rather than built into the base paytable odds. This means the certified RTP figure already includes Bonus Number payouts in its calculation, which is why pklock's Keno RTP remains competitive even at the highest multiplier tier.
For responsible comparison: a standard video slot at pklock carries an RTP of 95%–97% per game, while a live Roulette table sits around 97.3%. Keno's 95.5% RTP places it in the same bracket as most specialty casino games, with the advantage of a fixed-draw structure that many Bangladeshi players find more transparent and easier to manage emotionally than a continuous-spin slot session.
One important note for players depositing via Rocket or Dutch-Bangla Bank: there is no difference in payout processing between payment methods for Keno winnings. All withdrawals — whether to bKash, Nagad, or a BRAC Bank account — are processed from the same pklock wallet balance. The only variable is the withdrawal processing time, which averages 5–15 minutes for mobile money methods and up to 24 hours for traditional bank transfers.
Yes. If the Bonus Number matches one of your selected numbers but none of your picks appeared in the standard 20-draw, you still receive a base single-match payout multiplied by the Bonus Number factor. It will not be a large payout, but it is a real win credited to your pklock wallet.
Yes. pklock's Keno RNG is certified and independently audited. Each draw result uses a seed that is publicly verifiable post-draw. The Bonus Number is drawn from the remaining pool after the 20 standard numbers are selected, using a separate RNG call — both are logged in your draw history for review.
In Classic Keno at pklock, the Bonus Number is a single ball — it can only match one number. However, in Multi-Card Keno, the same Bonus Number is checked against all active ticket cards simultaneously, so if multiple cards contain that number, each qualifying card receives the multiplier independently.
Keno winnings are credited to your pklock wallet instantly at round close. Withdrawal requests to bKash and Nagad are processed within 5–15 minutes during normal operating hours. Bank transfers to Dutch-Bangla Bank, BRAC Bank, or City Bank typically settle within 1–24 hours depending on the time of your request relative to Bangladesh Standard Time (BST, UTC+6) banking windows.
Yes. The maximum single-round payout at pklock Keno is ৳5,000,000 per ticket. This cap applies after Bonus Number multipliers are included. High-roller players running multiple simultaneous tickets in Multi-Card Keno can achieve this cap across several cards independently in the same draw round.
Yes. pklock's Keno game is fully optimised for mobile browsers on Android and iOS. No app download is required — simply open pklock in your mobile browser, log in, and navigate to the Keno lobby. The draw animations and Bonus Number reveal are designed for portrait-mode screens and load quickly on standard Bangladeshi mobile data connections.
