Dicember 2017, Day 5: Ground Rules

Tales of a GM is running the 12 Days of Dicember, a project dedicated dice in all their randomized glory. The question for the fifth day of Dicember is “What is your rule for when dice roll off the table?”

Easy answer: re-roll it on the table. Doesn’t matter if it’s a critical hit or a critical fumble; if it hits the ground, you re-roll it.

A related rule is that a die must end its roll flat; it can’t be a “leaner” (meaning the top surface of the die can’t be at an angle). Dice that end up on a seam or crack may need to be re-rolled. To test, place another dice on top of the uneven die; if it slides off the die, the original die needs to be re-rolled.


  1. Hi Ken,

    That is an interesting rule about an uneven die. I may steal that as the house rule question for next year, although I doubt anyone would top your system.

    Also, that is a lovely die in the picture. I have a thing about blue dice, as you might guess.

    Thank you again for participating in The 12 Days of Dicember project

    1. Thanks! And thanks again for organizing the project! The “leaner” rule goes back to the very early days of our gaming group (so something like 21 years ago). I don’t recall how it originated, though I suspect it was my friend Nate’s doing. Regardless of who came up with it, the rest of us embraced it as a logical, fair, and often amusing house rule.

  2. Those are my rules, with one addendum. If you are rolling a set of dice and one or more fall on the floor, the entire set is re-rolled. Thinking about it logically, it doesn’t make much sense, but it’s been my rule from my early days of gaming.

    1. Hey David — thanks for stopping by! Nice house rule — I haven’t come across that one before. Sounds like exactly the sort of quirky rule that makes each group unique.
