📜 History
Keno traces back to ancient China; tradition holds that an early lottery form helped fund the building of the Great Wall. The Chinese original used written characters rather than numbers.
Chinese immigrants brought the game to the United States in the 19th century. There it was translated into numbers, and today it is a fixture of casinos and state lotteries alike.
🌍 Where popular today
Keno is common in the casinos of Las Vegas and is often played in a relaxed way — you can eat or chat between draws.
Many state lotteries across Europe and North America offer daily keno draws. Online it runs around the clock.
🎯 Rules
You choose between 1 and 10 numbers from a field of 80. Then 20 winning numbers are drawn.
Your payout depends on how many of your numbers are drawn — and how many you picked in total.
📊 Odds & maths
Keno carries one of the highest house edges in the casino — typically 25% to 29% depending on the pay table.
The probability of hitting all 10 when you pick 10 numbers is roughly 1 in 8.9 million. That is why payouts for many hits are so large.
✨ Beginner's guide
Never played keno? At heart it is a lottery: pick numbers, hope they are drawn. No strategy changes the odds.
Picking fewer numbers raises your hit rate per number; picking more raises the possible payout. Try both approaches here, risk-free.
