NoU is a lottery-style gambling game that is popular in modern casinos and is also provided by several lotteries. Players place bets by selecting numbers ranging from 1 to (typically) 80. If their number selection matches one of the winning numbers, the player wins that amount. Keno is played with a set of 79 balls, each with a different number from 1 to 80 assigned to it. The player picks numbers to match against the winning numbers on screen, which are drawn at random from these balls. When matching all selected numbers, the player wins the amount on offer. There are two types of Keno games: standard and progressive. In standard Keno, the prizes are fixed and calculated when you make your bet. In progressive Keno, the prizes increase as they are won, so they can be very high. Often, the more numbers you pick, the higher your chances of winning. Keno is played all over the world, but it is found most frequently in Asian countries like Japan, China, and India. It is also popular among Canadians who travel to the United States because many US casinos allow Keno to be played as long as you stay within their borders. In recent years, mobile apps have become available for both standard and progressive Keno.
