While big wins do occur, and fun is to be had here, the perennial aggravation for me is the devious 'dead zones'. These are the winless doldrums the designers put on players who have the gall to bet big. When you play modest wagers, bonus rounds are quite attainable. But when you start to bet, say, 20 million and up, you can hit spin literally til your thumb gets sore: no bonuses. Sectets of Hyde game: hit 2- bottles teaser 50(!) times; third bottle (which triggers bonus play) not once.
