If payment of the minimum top prize for the 8, 9, or 10 spot winners will exceed the $1,000,000 The balance of the maximum liability of $1,000,000 will be paid to winners in proportion to the amount wagered. If the maximum liability of $1,000,000 for any 8, 9, or 10 spot games is exceeded, all winners will be paid the minimum top prize allowed for that spot for a $1 wager. The top prize for the 8, 9, and 10 spot games are each capped at a maximum liability of $1,000,000 per draw. EXAMPLE: The prize for matching 7 numbers on an 8 spot game is $500, if the SPIN number is 10, the total prize is $5,000. Finally, since the multiplier costs and additional $1 to play, I divide the overal return by 2 in order to get the return per dollar bet and overall house edge.įor the 30% promo, I simply added 30% to the return of each possible combination.If you played KENO with SPIN, find your base KENO prize, then find the prize associated with the SPIN number. I then calculated returns based on the combined probability of multiplier and numbers matched. To calculate the impact that the Multiplier has on the return, I created a table of all possible outcomes of matched numbers and multiplier results. I wonder if the wheel weights change slightly during the 30% promo, or if 10k samples is not enough to get closer to the 1 in 1.33 number stated by the Georgia Lottery.īase Game Return with Multiplier and 30% Promotion (7 spot): The 10098 sample produced odds of 1 in 1.32069 (pretty close). Per the official Keno rules, the overall odds of a Multiplier being 2x or greater are 1 in 1.33. I calculated the natural wheel probabilities and then downloaded 10098 trials to get the actual wheel weights (I suspected that the wheel was not naturally weighted.) Here are the results:Īccording to the 10098 trials downloaded, the wheel is not weighted naturally. The wheel is made up of 5 '1x' spots, 6 '2x' spots, 4 '3x' spots, 2 '5x' spots and 1 '10x' spot. This portion was as simple as using The Wizards Keno Calculator: Any corrections or feedback would be greatly appreciated. I THINK I have calculated the returns for all the applicable betting combinations (excluding the max payout limits). (2) Sometimes they run a '30% more' promotion where for a limited time (usually Monday 6-8PM) all winnings are increased 30%. However, there are two wrinkles: (1) for double the bet, you can buy a 'Multiplier'.

The Georgia Lottery's Keno game is standard Keno (20 numbers picked from 1-80).
