About Keno
Keno is a lottery-style game where players select numbers from 1 to 80. The casino then draws 20 random numbers. Payouts are based on how many of your selected numbers match the drawn numbers.
The house edge in keno is typically very high (25-40%), making it one of the worst bets in the casino. However, it offers the potential for large payouts with small bets.
Key Facts:
- 80 total numbers available
- 20 numbers are drawn each game
- You can typically select 1-20 spots
- More spots = higher potential payout but lower probability
