Keno
Keno’s roots are in China, and the game was brought to the United States by Chinese immigrants in the late 1800s. It was originally played with 80 Chinese characters, which in the United States were replaced by 80 Arabic numerals.
The player then takes the card to a keno writer and places a bet that the numbers selected will be among the 20 drawn in the next game.
A four-spot ticket with $1 wagered might return the $1 if two numbers hit, bring $5 if three numbers hit, and pay $120 if all four come in. Paybacks range from below 70 percent to more than 80 percent.
Straight ticket: Betting the numbers marked as a single wager is called betting a straight ticket.
Combination ticket: The player marks several number groupings and plays combinations of them.
Video keno is essentially the same game – the player has the same 80 numbers arranged in the same eight rows on a video screen.
