RPG Dice is intended to be a universal RPG dice roller. This page allows you to roll virtual dice using true randomness, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. It only takes a minute to sign up. It's not there yet, but it's coming along.
Integrate it with basic HTML and CSS or any other means of graphical representation you wish to apply for displaying the dice and their values to the user. I hope to get feedback on that soon. In this tutorial we will look at random number generation, rounding numbers, allowing the user to specify how many times to roll the dice and displaying this on the web page.
