🎰 Keno Player Guide

Welcome to Keno! Use this guide to understand how to play, how you win, and how your ETB balance is updated.

📖 How to Play

1
Pick Your Numbers: Choose between 1 and 10 numbers from the grid of 80. The more you pick, the higher the potential jackpot!
2
Set Your Bet: Enter your wager amount in ETB. Your potential winnings will update automatically based on your "Pick Count."
3
The Draw: The system draws 20 random winning numbers. If your picks match the drawn numbers, you "Hit."
4
Get Paid: Winnings are calculated as Bet × Multiplier and added to your balance instantly.

📊 Official Payout Multiplier Table

Your winnings = Bet Amount × Multiplier. If a Hit count is not listed for a Pick, the multiplier is 0x (Loss).

Pick 101x0002x4x12x40x400x2500x5000x

Note: The 1x payout for 0 hits on Picks 8, 9, and 10 is a "Consolation Prize" because missing 20 drawn numbers while picking 10 is mathematically difficult.

💰 Win Examples (ETB)

The "Jackpot" Scenario:
You bet 50 ETB and pick 10 numbers. You hit all 10!
50 ETB × 5000x = 250,000 ETB Win!

The "Consolation" Scenario:
You bet 50 ETB and pick 10 numbers. You hit 0 numbers.
50 ETB × 1x = 50 ETB (Money Back)

The "Loss" Scenario:
You bet 50 ETB and pick 7 numbers. You hit 2 numbers.
50 ETB × 0x = 0 ETB (Better luck next time!)
