>Why only 16 of the possible 18 tiles would ever have the Whammy, I have no speculation. I'll speculate. I imagine they simply never audited the 5 patterns for full "whammy coverage". They just created 5 random patterns and didn't think any more about it. If they'd only had 3 or 4 patterns, maybe there would be a couple more whammy-less spaces. If they'd had 6 or 7, perhaps there wouldn't be any, just through random chance.
