# How to Roll Dice Like an MIT Nerd

Lost your d6? Flip three visually distinct coins, and use binary.

This Instructable is another cool way to substitute for a standard 6-sided die, and reminded me of the extremely geeky method we use. A great teaching tool for kids, too.

## Step 2: Understand Binary

This is pretty easy.

Designate one coin for each of the following:

20 = 1 (assigned to the penny)

21 = 2 (assigned to the nickel)

22 = 4 (assigned to the dime)

Heads = yes, tails = no.

Flip (or shake and dump) your coins and add the values to figure out the value of your roll.

I saw the other one yesterday morning, and was reminded of this trick. I don't think there's a secret Illuminati dice plot.

Reminds me of an xkcd comic where a biologist says into a voice recorder:
"The eagle has left the nest."
*khhhkht* "Roger that, eagle has left the nest, alert the agents." *khhhkht*
"Will you stop that?"

Aaahh, but how would you get a d20?! That would come in very handy when I don't have my d20 on me and someone says "roll for damage" when I burn someone.

Just use more coins...

20 in binary is:
10100
So just use 5 dice then.

You could simulate a d100 if you really wanted with 7 dice.
64 32  16   8    4    2    1
1    1    0    0    1    0    0

This is great and all (I'm goin' camping this weekend and I forgot my dice), but is it really accurate?
5 years ago
it is perfectly accurate, provided the two non-die rolls are discounted. the zero/8 and 7 combintions would throw off any die probabilities, but other than that, the remaining six possible combinations all correspond to a single die face, so the probabilities work out the same as rolling a die.

I love it! My friend's always forgetting the die for D&D games.

Good Idea. Another way that you could do with any coins (same or not) is to simply assign heads as 1 and tails as 0 and just read the coins left to right. So a H-T-H would be 101 witch is 5.
7 years ago
It could also be 6 or 3 as well, depending on where you dumped the zero. One would have to drop the coins one at a time to do it with the same coin. Or it could be done three times with the same coin for that matter.
