Keno is a similar-to-lottery, gambling game often played at modern casinos. The game was originated in China and its widespread popularity helped in raising funds to build the Great Wall. Keno is extremely easy to play, and most importantly, it offers the possibility of winning large pay outs on comparatively small gambles.
- A traditional casino keno game makes use of a fairly large and transparent circular glass enclosure, known as a ‘bubble’. The bubble holds eighty balls which determine the draw results.
- Every ball is imprinted with a number from one to eighty. During the draw, a blower thrusts air into the bubble enclosure to mix the balls together.
- The ‘caller’ then pulls a lever leading to a tube opening, where the balls get lifted one at a time into a ‘V’ shaped tube. This ‘V’ shaped tube is called the ‘rabbit ears.’
- The caller and a checker make note of each of the twenty balls blown into the tube. Finally, the automated keno system works out all bets based on the numbers drawn by the player.
- The players are awarded payouts on the basis of how many numbers drawn from the glass enclosure match with the numbers selected on the keno ticket. Payouts also depend on the pay-table selected by the player. Two keno pay tables from different casinos are never identical.

In modern keno, balls may be chosen by any of the following four methods : (1) traditional blower (rabbit ears), (2) automated blower where encoded balls are used, (3) electronic random number generator, and (4) hand cage, where validation of selected balls is needed. People are also offered the choice of playing multi-race games where a keno ticket is booked for many consecutive keno races.
