Keno at Land Casinos
Usually, keno games found at land casinos start at $2 per ticket and have you pick nine numbers out of 80. The odds of you picking all nine are a little more than 1.3 million to one, and jackpots usually cap out at $250,000. The allure of the game is largely rooted in the potentially large reward for small amount wagered. So why do casinos have Keno if it carries such poor odds?

Casinos have Keno games for a couple reasons:

• To diversify their selection of games. It appeals to a different type of player than the craps or baccarat player because anyone can understand its simple rules. As you would expect, it's popular with lottery buffs.
  
  
• It makes a nice profit for the house. Keno lounges usually occupy a considerable amount of space on the casino floor. To ensure a decent monetary return per square foot, casino operators require a hefty house advantage.

Keno at Online Casinos
Playing Keno at online casinos is almost identical to the version found at land casinos with a few exceptions:

• Players choose a minimum of ten numbers, sometimes as many as fifteen.
  
  
• The jackpots usually aren't as high as 250,000 credits
  
  
• Tickets can be purchased for as little as 1 credit
  
  
• The time in between games is short, so you can play more games in less time.
