Keno by TvBet
Introduction
This page describes the keno game offered by TvBet, a provider of live dealer games to Internet casinos. The reason I created a special page for their keno game, when I already have a page on keno, is they added quite a few side bets.
Rules
As in standard keno, 20 balls will be drawn, without replacement, from a hopper containing balls numbered 1 to 80. Depending on the bet the player makes, he may be asked to picks his own numbers before the draw. TvBet has one game every three minutes.
The pays listed on this page are those offered live, as opposed to those listed in the help file.
Standard Keno
The following table shows the pay table, hit frequency, and expected return for picking 1 to 10 numbers. The greatest return is on the pick-4 at 94.82%.
