Role Playing Games (RPG’s) are event-driven hence require several kinds of dice, including variants you may never have seen or heard of. This microprocessor-based circuit can generate them all and should delight RPG players.If you throw a die on a tabletop and let it roll for a second or two, you expect it to tell you a random number in the range from one to six. This particular range is determined by the physical shape of the die, which — in its classic form — is a cube. Rolling two or more dice gives a wider range of numbers with a corresponding decrease of the chances that a certain value is obtained.An electronic version of, say, a fistful of dice requires a circuit exhibiting at least a fair degree of pseudo-random behaviour.
