Im not sure about what everyone else thinks but after the changes that were implemented when we started to have to log-in with user name and password has someone changed the game structure.  A few things of note:
1. because of the flash or whatever else type of program it uses, after a bit of play, the game significantly slows down (meaning i cant press the bet button quicker if I chose to)  
2.  After a number of bets rolled, the bet amount keeps increasing gradually.  Sometimes I will bet at 0.001 and without my knowledge, it has changed to 0.00167 (which means that from 0.001, it went to 0.00113, 0.001146......... gradual increase)
3. granted that the site shows the provably fair hashes for the previous bet rolled but I have way too many times, enough to the point that i have taken notice that, bet a roll at lower than 6618 and the bet outcome, when its a close roll) coincidentally a roll between 6640-6714 (estimated range)
4.  at a 50.25% chance win, very very rarely, if that have I rolled a loss like 6 or 7 times in a row but it happens quite frequently now and I believe that the new program implementation along with the slowness of the rolls, regardless of the show provably fair hash results, are causing this to happen.  

These are just my personal observation after playing this site for quite sometime now.  I can't verify the above with concrete data but I think it's enough for me to take the time to voice my opinion on here.
