I Am The Laziest Die Roller
My gaming tables tend to be as organized as my computer desk . . . which is to say, "Completely not organized, oh help, I just pulled a load-bearing pencil and now I'm buried." As a result, I don't necessarily have the dice I need at my fingertips. But I'm lazy; I'll just roll whatever's handy that gets the job done.
For example, we're currently playing a Dungeons & Dragons campaign in our house. Unlike GURPS, which keeps things easy by just using good old six-sided dice, D&D employs a jillion different dice. But who has time to find a four-sider when you need it? So I just toss an eight-sider and divide by two. (Heck, I'll even use this method if I can find my four-siders; I just like how eight-siders roll better.) If I need to randomly determine which of five targets are getting hit, maybe I'll use a 10-sider and divide by two. Maybe a 20-sider and divide by four. Maybe a six-sider, rerolling sixes.
This works even when I can find my dice, but I just need more dice. Does a particularly nasty damage roll require a bunch of 10-siders? I've used the custom percentile dice and ignored the zero at the end. I've rolled 20-siders. Heck, in a pinch, I've dropped a 12-sider down the ol' dice tower and just rerolled 11s and 12s. After all, 83% of the time, it works perfectly.
If you're the same way, or if you have some other weird randomizer quirk, I'd love to hear about it on the forums!
