Random Dice Roller will allow you to generate a random dice roll for your RPG needs. The program is set up so that you can enter the number of dice to roll as well as how many sides the dice must have. Most often dice will need to be of various sizes. Most RPG's use 6 sided dice as well as 12, 20, 10, 8, 4, sometimes 100 sided. We've even seen a 34 sided die!!
