Poker Casino Online : Keno (Rules, Tips, Helps)
Keno payouts are based on how many numbers the player choses and how many 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 from casino to casino. Most casinos allow paytable wagers of between 1
and 20 numbers, but some limit the choice to only 1 through 10, 12 and 15 numbers, or "spots" as
keno aficionados call the numbers selected.
The probability of a player hitting all 20 numbers on a 20 spot ticket is approximately 1 in 3.5 quintillion (1 in 3,535,316,142,212,180,000 to be exact). If every person now alive played one keno game every single second of their lives, there would be about one solid 20 jackpot-winning ticket to date. If all these possible keno tickets were laid end to end, they would span the Milky Way galaxy -- and only one of them would be a winner. 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 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:

The balldraw occurs at the "keno booth". The balldraw is typically determined by one of four devices:
1. Traditional “Rabbit Ear” blower
2. "AKV": Automated blower in which the balls are encoded, read by a computer, then sent to a computerized keno system for processing
3. Random Number Generator: An electronic number selection device approved by gaming authorities
4. “Hand Cage”: A spinning the metal ball cage which rolls the numbers into a slot where they are validated by a person
"Keno runners" walk around calling, "keno!" and offer to carry players' wagers to the keno booth for processing. The keno runner is handed the wager payment and the “inside ticket” (keno wager forms filled out by the customer) and takes the wager and ticket to the keno counter for processing. The keno runner returns with an "outside" ticket, which is the official wager receipt. It is incumbent on the player to check the ticket for errors before the game balldraw is drawn. Any errors not corrected before the balldraw begins are not normally rectified and the "outside" ticket receipt governs in any disputes.
In modern keno, players are offered the option of playing multi-race keno, which books a keno ticket for a number of sequential keno races up to 1000. The races must always start on the next sequential race to be drawn. When the sequence of wagered games is finished, the player is able to redeem any winnings within the time constraints specified in the casino's rules booklet.
After picking wager numbers, recording them at the keno booth and obtaining the “keno ticket” (official wager receipt), the player watches the balldraw in progress as the spot (number) selections light either on an electronic keno board or on a video monitor. Keno displays are typically found throughout the casino and sometimes even appear on a television channel in casino hotel rooms.
In the past, a winning ticket needed to be taken to the keno booth for collection immediately after the race results were posted, and drawings usually took place approximately every five or six minutes. In days of old, if the player tried to redeem a winning ticket after the next sequential race began, the ticket was declared expired and no money was paid out even if it won. Nowadays most casinos set their "late pay" window to accommodate the player, however there is great variation in the published late pay window from casino to casino. Tickets played for 21 races or more typically offer one year for collection in most major gaming jurisdictions. Tickets played for under 21 races have a great disparity of late pay rules from casino to casino. Keno players are wise to read the rules published in the host casino's keno paybook to determine when a keno pay will expire and become uncollectible. Gaming authorities require that all pay scales and keno rules be posted in a prominent location in keno areas.
An embellishment of keno is “way” keno or “combination” keno. When playing a way or combination keno ticket, the player circles groups of numbers within the spots marked and specifies combinations of groups which combine together to make different "ways". For example, if a player marks four numbers, and circles two groups of two spots each, a combination ticket could be made in which the gambler plays one 4 spot and two 2 spots (2-2). If an additional group of two were added and circled, the player could play ways 1/6, 3/4 and 3/2 (2-2-2), which at $1.00 per way would create a $7.00 per race wager. Serious keno players use great imagination on keno tickets to make complex combinations of groups and ways with varying numbers of spots in each group. There is literally no limit to the way players can circle spots of like or a differing number of spots and in the resulting “ways” they can choose to play on a keno ticket.
As alternatives to traditional paytables which offer the selection of 1 to 20 spots, a number of special paytables are available and are often offered as a wager choice. For example, with the Top/Bottom paytable the keno player does not select any spots. Rather, the player is betting that the balldraw top 40 and bottom 40 ball distribution will be uneven. Top/Bottom typically begins paying on a 7/13 or 13/7 ball distribution between the top half (1 to 40) and bottom half (41 to 80) of the keno grid and the payouts increase with each higher balldraw distribution disparity. The same principle is applied for the Left/Right or Odd/Even paytables. Other specialty paytables are Top Only, Bottom Only, Left Only, Right Only, Odd Only, Even Only, Parlay, Exacta, Edge, Square, or eXtra Million, which is proprietary to XpertX Keno Systems. However the traditional 1 though 20 spot pick is by far the most popular variety of live keno.
Lottery versions of keno are now used in many National Lotteries or state licensed Lotteries around the world. The games have different formulas depending on the wanted price structure and whether the game is slow (daily or weekly), or if it is a fast game with just minutes between the draws. The drawn numbers are typically published on TV for the slow games and on monitors at the point of sale for the fast games. A video keno machine sometimes has a greater customer edge than a traditional keno game. However, because live keno payouts are configurable at will by the host casino, some live keno paytables house hold percentages match or are even lower those for video keno machines, which almost always have fixed paytables that don't change.
