Tunnels & Trolls task resolution benchmarking
Tunnels & Trolls has the first universal task resolution procedure in gaming. It's called the saving throw, after the D&D procedure. The Judge is expected to apply the results of this procedure to the fiction in a totally organic fashion. This is radical stuff! The procedure is quite simple: roll 2d6+stat, against a target number of 15+(5*difficulty). A roll of doubles on the 2d6 "explodes"; add another 2d6 and repeat this step. If the total of the 2d6 roll(s) is/are 4 or less, the task fails. Succeed or fail, the player gets (roll+stat)*difficulty experience points. I need a hard modelling surface to apply a "pick your own difficulty" procedure like this. I want to know what the odds are for a normal person to succeed at a given task. That way I can set the task's difficulty level irrespective of the player's actual stats. To that end, I simulated 200k dice rolls and counted them up.
