Well I was just playing a game of Triple Dice Poker, and thought I would share how I went from having 2 rolls to it being my last roll. After my first roll, I selected a dice to re-roll and I accidentally double clicked on the "roll dice" button, and it went strait to being my last roll - skipping 1 roll. (I can hit "back" on my browser, and says I have 2 rolls left - hit forward on my browser, back to all rolls already taken)

Anyway, I wanted to mention this because I remember others complaining at times that they "lost" their rolls while playing - and double clicking on "Roll selected dice" can explain that issue.
