What's going on here? I notice that every time I increase my bet to a reasonable amount, I lose. Regardless. If I change to hi/lo, so does my roll....

So annoying as it's entirely possible this is luck. It's also entirely possible that it's programmed this way. Win rolls are always instant - loss rolls take a little extra time to go through? Is this a bug on the site?
