Extra Draw Keno

Introduction

Extra Draw Keno plays like conventional keno, except after the ball draw the player may purchase more balls for the price of his original wager. This page addresses the most common version found on IGT Game Makers, with three extra balls. There is also a version I've see in Amsterdam that offers two extra balls. The option is not offered if it is an extremely poor bet. The player wins according to the final ball draw, whether he chose the extra balls or not.

Following are three pay tables that I know of. The return is in the second to bottom row. The return is measured as the ratio of the total win less cost of the extra draw to cost of the initial draw. The bottom row shows those number of catches in the first 20 balls where the odds favor paying for the extra draw. For example, "36789" means to buy the Extra with 3, 6, 7, 8, or 9 catches in the first 20 balls.

Pay Table 1 has a maximum return of 87.66% on the Pick 6. On the Pick 6 the correct strategy is to buy the extra draw with 4 or 5 wins after the first 20 balls.
