Keno/kiːnoʊ/ is a lottery-like gambling game often played at modern casinos, and also offered as a game by some state lotteries.
Today, online keno allows gamblers to enjoy new drawings anytime they like, with the potential to win huge sums of money every time a new set of numbers is drawn. How to Play Keno Online. Online keno is a very easy game to play, especially if you’ve tried a lottery before. Here’s a look at the Keno playslip. Every 4 minutes (except during system processing), the Lottery will select 20 winning numbers. The goal is to match your numbers to the ones selected by the Lottery. To understand how much your Keno ticket will cost, multiply the amount wagered per draw by the number of consecutive draws played.
Players wager by choosing numbers ranging from 1 through (usually) 80. After all players make their wagers, 20 numbers (some variants draw fewer numbers) are drawn at random, either with a ball machine similar to ones used for lotteries and bingo, or with a random number generator.
Each casino sets its own series of payouts, called 'paytables'. The player is paid based on how many numbers were chosen (either player selection, or the terminal picking the numbers), the number of matches out of those chosen, and the wager.
There are a wide variety of keno paytables depending on the casino, usually with a larger 'house edge' than other games offered by that casino. The house edge ranges from less than 4 percent[1] to over 35 percent.[2] The typical house edge for non-slot casino games is under 5 percent.[3]
History[edit]
The word keno has French or Latin roots (Fr. quine 'five winning numbers', L. quini 'five each'), but by all accounts the game originated in China. Legend has it that the invention of the game saved an ancient city in time of war, and its widespread popularity helped raise funds to build the Great Wall of China. In modern China, the idea of using lotteries to fund a public institution was not accepted before the late 19th century.[4]
Chinese lotteries are not documented before 1847 when the Portuguese government of Macau decided to grant a license to lottery operators. According to some, results of keno games in great cities were sent to outlying villages and hamlets by carrier pigeons, resulting in its Chinese name 白鸽票 báigē piào, literally 'white dove ticket', pronounced baak-gap-piu in Cantonese (on which the Western spelling 'pak-ah-pu' / 'pakapoo' was based).
The Chinese played the game using sheets printed with Chinese characters, often the first 80 characters of the Thousand Character Classic, from which the winning characters were selected.[5][6] Eventually, Chinese immigrants introduced keno to the US in the 19th century,[7] where the name was Westernized into boc hop bu[6] and puck-apu.[5] By 1866, it had already become a widely popular gambling game in Houston, Texas, under the name keno.[8]
Probabilities[edit]

Keno payouts are based on how many numbers the player chooses and how many of those numbers are 'hit', multiplied by the proportion of the player's original wager to the 'base rate' of the paytable. Typically, the more numbers a player chooses and the more numbers hit, the greater the payout, although some paytables pay for hitting a lesser number of spots. For example, it is not uncommon to see casinos paying $500 or even $1,000 for a 'catch' of 0 out of 20 on a 20 spot ticket with a $5.00 wager. Payouts vary widely by casino. Most casinos allow paytable wagers of 1 through 20 numbers, but some limit the choice to only 1 through 10, 12, and 15 numbers, or 'spots' as the numbers selected are known.[9]
The probability of a player hitting all 20 numbers on a 20 spot ticket is 1 in 3,535,316,142,212,174,320.[10]
Even though it is virtually impossible to hit all 20 numbers on a 20 spot ticket, the same player would typically also get paid for hitting 'catches' 0, 1, 2, 3, and 7 through 19 out of 20, often with the 17 through 19 catches paying the same amount as the solid 20 hit. Some of the other paying 'catches' on a 20 spot ticket or any other ticket with high 'solid catch' odds are in reality very possible to hit:
| Hits | Probability |
|---|---|
| 0 | 1 in 843.380 |
| 1 | 1 in 86.446 |
| 2 | 1 in 20.115 |

| 20 | 1 in 3,535,316,142,212,174,320.000 |
Probabilities change significantly based on the number of spots that are picked on each ticket.
