Sharing a lot of the same characteristics as bingo or lotteries, keno was a game that flourished in physical casinos in the 20th Century. It's no longer as popular now, but it has found a whole new wave of players online. Keno is a game that's easy to play and moves along quickly, offering the chance to win big jackpots for relatively small wagers. Though it doesn't offer very good odds compared to other casino games, it still offers thrills without asking much of its players.
The name for keno is actually a French word that means “five winning numbers,” though the game itself is thought to have originated in the Far East. In its most traditional form, players pick 20 different numbers between 1 and 80. Once the players' selections are made, 20 numbers are selected from a machine that looks like a lottery or bingo machine. Prizes are awarded based on how many of a player's numbers match the ones that are drawn, with more money going to players who got more numbers correct.
When it's played online, the keno numbers are selected by a random number generator that simulates the drawing of the ping pong balls in a physical game. Online keno moves faster as a result. Online casinos have also come up with a wide range of different twists on the standard game, including having the players select less than 20 numbers, the ability to wager the same numbers for multiple drawings occurring at the same time, and many more. Keno has also proven to be a great canvas for different graphics and themes.
The odds of correctly matching all 20 numbers in a given round of keno are so astronomical that they almost aren't worth discussing. Suffice it to say that if it happens even once in all keno games that are played all around the world during your lifetime, it would be a great surprise. With that in mind, most keno games award the top prize to anyone matching even most of the numbers correctly. The randomness of keno makes it difficult to recommend a particular strategy, but one thing to watch is to see if picking fewer numbers in exchange for smaller wins is an option. This can help you maximize your playing time if that's a priority for you.
