Cascade Dice are a simple system for generating stories and story setups using 2d6.
Roll dice, check tables (or don't, this thing is fairly quick to memorize), and let the brain do the rest. Unsure what to make of a roll? Take the first thing that comes to mind, or roll again to gain more clarity.
Includes a short example using the dice to generate a general story premise with no initial constraints, and a longer example using the dice to outline a story start-to-finish, following an initial setup.
