Dice always seem to disappear from old board games. With Extra Dice, you always have a backup at hand. In this app, you can roll as many dice as you want, and you can choose between traditional 6-sided dice, or less common polyhedral dice (4-sided, 8-sided, 10-sided, 12-sided, 20-sided, or any other custom number you choose). When rolling, different sounds are played depending on how many dice you have (with the ability to turn the sound off). Your settings are always saved, so you'll come back to your dice however you left it. Simple but powerful design, easy to use.
