Last month, during a stay at my local Harrahs, I discovered that a bank of dedicated (only Keno) machines were allowing me to accumulate points at $5=1 Tier Credit, just like a slot machine would. I know that, normally, video Keno games are found on mixed Game King machines that include mostly video Poker games and give you $10=1 Tier Credit. Are there video Keno machines in Las Vegas (whether Total Rewards or MLife) where you accumulate points the same as playing slots? I have never really noticed but, again, when I playing, it is typically not on a dedicated video Keno machine. I am particularly fond of the Caveman Keno game and, from what I've seen, while the payback percentage is not as good as Video Poker, it is better than most slots and I enjoy the "mindlessness" of playing it. Would like it even more if I was earning tier credits at the higher rate.
