The computer actually uses a pseudo-random number generator (PRN), but the effect is the same.</P> <P>A 100 sided dice produces a number between 1 and 100. The open part of the roll adds the following rules:</P> <UL> <LI>If the roll is greater than 95, roll again and add the result. <LI>If the roll is less than 5, roll again and subtract the result. </UL> <P>These rules are applied recursively, so very high and very low rolls are possible (but unlikely).</P> <P>There is about a 1 in 20 chance of rolling unusually high and an equal chance of rolling unusually low. A second roll in either direction occurs about 1 roll in 400, and a third about 1 in 8000.</P> </BODY> </HTML>
