99% player odds doesn't sound good. Reduced House Edge 1%!! Does the trick magnificently from a consumer standpoint IMO... That was what drew me in initially from Satoshi Dice.
That's because SD had already framed the discussion in the "house edge" terms, and in your head, perhaps just subconsciously, you wanted to compare it with SD on their terms. For someone not already accustomed to SD's marketing, what version is demonstrably better at getting them to gamble more? Again, this is why I merely suggested an A/B test. Nothing sinister implied - I'm not identifying the 99% side as being better, I'm questioning the method used to come to the conclusion that 1% is better. The reason I brought it up is that since casinos generally put the larger number on their marketing materials, and they are in the business of convincing people that gambling is a good idea, they probably know what works to reel the largest number of people in. But I don't know how that translates into the world of bitcoinlandia, because the psychology of the players may be different. It may be true, it may not. I have no idea.
