299ba Keno Bonus Number — Pick Your Lucky Numbers and Win Up to ৳500,000 in Bangladesh
Bangladesh's most exciting online keno experience is right here at 299ba. Choose up to 10 numbers, watch the live draw, and collect multiplied payouts when your Bonus Number hits.
What Is Keno Bonus Number at 299ba?
Keno is one of the oldest lottery-style games in Asia, and 299ba has brought it into the modern era with a unique Bonus Number twist that dramatically increases potential payouts. The concept is simple: a pool of 80 numbered balls sits in a virtual draw machine, and each round the system randomly selects 20 of those numbers. Before the draw, you choose anywhere from 1 to 10 numbers — called a "spot" — and stake any amount from ৳50 upwards.
What makes 299ba's version stand out is the dedicated Bonus Number. At the start of every round, one special ball is flagged as the Bonus Number before the main draw begins. If your selection includes the Bonus Number and it appears in the draw results, your standard payout is multiplied — by up to 5× depending on how many of your other picks also matched. This single mechanic turns a quiet lottery-style session into something genuinely thrilling.
Players across Dhaka, Chittagong, and Sylhet have made Keno Bonus Number one of the fastest-growing categories on the 299ba platform — partly because draws happen every few minutes, and partly because the game requires no special knowledge or complex strategy. You pick your lucky numbers, watch the draw live, and find out your result instantly.
How to Play Keno Bonus Number
Getting started takes less than a minute. Here is the full process from login to payout — step by step.
Log In to 299ba
Access your 299ba account from any browser on Android or iOS. No app download is needed — the mobile site runs smoothly on all devices used across Bangladesh.
Navigate to Keno
From the main lobby, select the Keno Bonus Number category. You will see the live draw board, the current Bonus Number indicator, and the betting panel all on one screen.
Pick Your Numbers
Tap or click between 1 and 10 numbers from the 1–80 grid. You can select manually, use the Quick Pick option for a random selection, or save favourite number sets for future rounds.
Set Your Stake
Enter your wager — minimum ৳50 per round, maximum ৳50,000. You can also activate multi-round mode to repeat the same number selection automatically for up to 20 consecutive draws.
Watch the Live Draw
The draw runs every 3–5 minutes. Twenty balls are drawn from the pool of 80. Your matched numbers light up green on the board in real time — and the Bonus Number glows gold if it appears.
Collect Your Winnings
Payouts are credited to your 299ba wallet instantly after each draw. Withdraw any time via bKash, Nagad, Rocket, or Upay — no minimum withdrawal cooldown for verified accounts.
Pro Tip: Use the multi-round feature during peak draw times (typically 8pm–midnight BST) when prize pools on special event draws are boosted. Keno Bonus Number tournaments run during BPL and T20 World Cup seasons with enhanced multipliers across selected number ranges.
The 80-Ball Grid — Understanding the Draw
Below is a sample keno grid showing a 10-spot selection (gold border) against a completed draw result (green). The starred ball is the Bonus Number for that round.
Payout Table — What Each Match Pays
Payouts are calculated per ৳100 staked. The Bonus Number multiplier applies on top of the base payout when your selection includes the designated Bonus Number.
All payout figures shown per ৳100 stake. Bonus Number multiplier applies only when the Bonus Number was included in your original selection and appears in the draw result. Full terms apply — see Terms & Conditions.
The Bonus Number Feature Explained
The Bonus Number is the defining feature that separates 299ba's keno from a standard lottery draw. Before each round begins, one number from the full 1–80 pool is designated as the Bonus Number and displayed prominently on screen. This number participates in the main draw just like any other — it can be drawn or it can miss — but if it is drawn and you have selected it in your ticket, every matched number on your card activates the bonus payout multiplier rather than the standard payout.
The multiplier tier varies by how many of your picks matched in total. Matching 3 numbers including the Bonus Number on a 5-spot ticket, for example, pays out at the 3× multiplied rate rather than the base 3-of-5 rate. Matching all 10 on a 10-spot ticket with the Bonus Number included delivers the maximum 5× multiplier — the biggest payout on the entire 299ba platform at ৳500,000 per ৳100 staked.
During special seasonal events — Eid draws, Pohela Boishakh celebration rounds, and BPL cricket playoff nights — 299ba activates a Double Bonus Number round where two Bonus Numbers are designated simultaneously. Hitting both in a single ticket with a full match is the rarest and most rewarding outcome in the entire keno catalogue.

Playing Smart — Keno Strategy Tips
Keno is a game of chance, but how you manage your ticket selections and stake sizes can meaningfully affect your session outcomes.
Always Include the Bonus Number
The Bonus Number is announced before each round. If your budget allows only one guaranteed pick, make it the Bonus Number — it is the single highest-leverage selection on the ticket since it activates the multiplier for all your other matches.
Balance Spot Count with Risk
Picking fewer spots (3–5) gives you a higher hit rate but lower individual payouts. Picking more spots (8–10) is harder to hit but delivers massive multiplied returns when you do. Match your spot count to your risk appetite and session bankroll.
Use Multi-Round Mode Wisely
Multi-round mode locks your number selection across several consecutive draws — useful for riding a hot number streak without manually re-entering picks. Set a round limit that fits your total session budget so you don't exhaust your wallet before a bonus draw arrives.
Set a Session Budget First
Decide your total keno budget before your first draw — not during it. Players in Dhaka and Chittagong who report the most consistent enjoyment are those who treat keno as structured entertainment with a preset spend, not a recovery strategy.
Play During Bonus Draw Events
299ba schedules enhanced payout events around major cricket calendar dates — IPL finals, T20 World Cup knockout rounds, and BPL playoff nights. The enhanced multiplier rates during these windows make the same stake worth considerably more if the Bonus Number lands.
Track Your History
Your 299ba account dashboard keeps a full record of every keno round you have played — numbers selected, draws matched, payouts received. Reviewing this history helps you identify any patterns in your selection habits and manage your overall spend responsibly.
Deposit & Withdraw in Seconds
One of the biggest reasons Keno Bonus Number has grown so rapidly among players across Rajshahi, Sylhet, Khulna, and Barisal is how frictionless the 299ba payment experience is.
