Keno Bonus Number on GT99 app takes the classic number-picking game and adds a twist that can multiply your winnings in an instant. Simple to play, fast to resolve, and genuinely exciting when your numbers start hitting.
Keno is one of those games that's been around for centuries, and there's a reason it keeps showing up in every major gaming platform. The concept is beautifully simple: you pick a set of numbers from a board of 80, the game draws 20 numbers at random, and you get paid based on how many of your picks match the draw. The more you match, the more you win.
GT99 app's version — Keno Bonus Number — adds one extra layer that makes the whole thing considerably more interesting. Before each draw, a special Bonus Number is designated. If that number appears in your selection and gets drawn, your winnings for that round are multiplied. Depending on how many of your other numbers also hit, the Bonus Number can turn a modest win into something genuinely significant.
The game runs on a certified RNG, so every draw is completely independent and fair. There's no pattern to chase, no hot or cold numbers — just the pure probability of 20 balls landing out of 80. What you can control is how many numbers you pick, how much you stake per ticket, and whether you activate the Bonus Number feature on each round.
The Bonus Number is the defining feature of this version of keno on GT99 app. At the start of each round, one number from 1 to 80 is highlighted as the Bonus Number. You don't choose it — it's assigned by the system before the draw begins.
If the Bonus Number falls within your selected picks and it gets drawn, your payout for that round is multiplied by a factor that varies based on how many total matches you hit. The multiplier can range from 2× on a modest match count all the way up to 10,000× if you hit a full card with the Bonus Number active. That upper end is rare, obviously, but it's the kind of possibility that keeps the game genuinely exciting round after round.
You can choose to include or exclude the Bonus Number feature on each ticket. Including it costs a small additional percentage on top of your base stake — typically around 10% extra. For most players, that's a worthwhile trade-off given the multiplier potential it unlocks.
Keno is fundamentally a game of chance. The RNG doesn't have memory, and no number is statistically more likely to appear than any other. That said, there are a few practical decisions you can make that affect your overall experience on GT99 app.
The number of spots you pick (called your "catch" target) directly affects both the odds and the potential payout. Picking fewer numbers — say, 4 or 5 — gives you a higher hit rate but lower maximum payouts. Picking more numbers — 8 to 10 — reduces your hit rate but dramatically increases the top-end payout if you catch most of them. Most experienced keno players on GT99 app tend to settle somewhere in the 6–8 spot range as a balance between frequency and reward.
GT99 app also offers a Quick Pick option that randomly selects your numbers for you. If you're playing multiple rounds quickly and don't want to manually pick each time, Quick Pick keeps the pace up without sacrificing any of the game's fairness.

Before every draw on GT99 app, one number between 1 and 80 is flagged as the Bonus Number. If you've included it in your picks and it gets drawn, your total payout for that round is multiplied. The multiplier scales with your total catch count — the more numbers you hit alongside the Bonus Number, the bigger the boost. At maximum catch with the Bonus Number active, the multiplier reaches 10,000×. Even at lower catch counts, the Bonus Number typically doubles or triples what you'd earn from a standard ticket.
