Keno is a popular lucky number game which offers massive flexibility and excitement. Early versions of this game feature 120 Chinese characters, which were a distinct challenge for non-Chinese. Its introduction to US casinos saw Chinese characters replaced by Arabic numerals, and later numbers. Its lottery format makes it exceptionally easy to play.
China is the country with the world's highest population, and its second-biggest economy, which makes it a prime target for online casino operators. Chinese citizens are generally tech-savvy and have access to smartphones, meaning that the potential size of the online gaming community in the East Asian country is enormous.
