Now, for the game of Superball Keno itself. The machines at Viejas may be set up the same way. So it looks like a no brainer that the 9-spot would be the best to play. With the 10-spot you have to hit either 9 out of 10 or 10 out of 10 to win the progressive. With the 9-spot you have to hit either 8 out of 9 or 9 out of 9 to win the progressive. With the 8-spot you have to hit the solid 8 to win the progressive. With the 7-spot you have to hit the solid 7 to win the progressive. So you can take your pick as to how many spots you want to play.but the progressive meter is the same whether you are playing the 7,8,9 or 10. The 7-spot, 8-spot, 9-spot, and 10-spot are all progressive and all linked to the same meter. And in the Montana version this is what I found out: This is the Montana progressive version with a 50 cent bet and a max payout of 1600 for 1 ($800).
Yesterday I stumbled upon a couple of old Pot O' Gold machines with Superball Keno on them.
