I now have all 3 Half Pie Stratosphere chips. I had already owned the Kolassal Keno and 10 of 10 Keno chips. I have never actually seen the Slot Tournament chip before. I asked Doug Saito and he said he had never seen one and told me check with Walt D. who also said he never had seen one.
Well a friend told me about one on E Bay and now I own all three.
