Keno Dragon is an exciting game that was first introduced in China around 200 B.C. It came to the United States with the immigrants and over time evolved into the game you now see before you. Keno is played with a traditional 80-numbered ticket and 20 balls whose function is the same as in a standard lottery. The player marks from 1 to 15 spots on the ticket and is paid according to the numbers that roll out on the balls and the bet he or she chose.
