Understanding the Bonus Number Feature
The Bonus Number is what separates Keno Bonus Number from standard Keno — and it is the feature that spribe players in Karachi and across Pakistan talk about most. Understanding exactly how it works is essential before you set your stakes.
After the 20 regular draw balls have been selected, the game designates one of those 20 drawn balls as the "Bonus Number" for that round. This designation happens after the draw is complete but is revealed to the player with a distinct visual and audio cue — on spribe's mobile interface, the Bonus Number pulses with a bright teal glow that is immediately recognisable.
The Bonus Number can only benefit you if it matches one of your selected spots. If it does, the payout for that specific catch is multiplied — with the exact multiplier depending on your total number of catches and the number of spots you selected for that round. This means the Bonus Number reward is context-dependent: hitting the Bonus Number on a high-catch round (say, 8 out of 8 spots matched) produces a dramatically higher total payout than hitting the Bonus Number on a low-catch round.
Players in Islamabad who prefer a methodical approach often choose 5 or 6 spots specifically because the Bonus Number multiplier at mid-level catch counts hits a balance between frequency and reward that is hard to match with either extreme (1–2 spots vs 9–10 spots). At spribe, the Bonus Number probability remains consistent across every round — it is always exactly 1 of the 20 drawn balls, regardless of how many spots you selected.
Probability Note: The chance that the Bonus Number coincides with one of your selected spots depends on how many spots you picked. With 10 spots selected, the probability that the Bonus Number is one of your spots (given it has been drawn as one of the 20 balls) is proportionally higher than with 2 spots. However, the Bonus Number does not alter the base RTP of 95.5% — it redistributes variance by adding high-multiplier events to the payout distribution.
