## Introduction: 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 1: Acquire Coins

It happens all the time: you open your favorite board game, and the die is gone. What to do?

Coins are readily available.

Just find three visually distinct coins: I've got a dime, nickel, and penny here, but you could mark up three of the same coins with a Sharpie to distinguish them if necessary.

## Step 2: Understand Binary

This is pretty easy.

Designate one coin for each of the following:

2^{0} = 1 (assigned to the penny)

2^{1} = 2 (assigned to the nickel)

2^{2} = 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.

## Step 3: Scoring Examples

Remember: dime: 2^{2}=4, nickel: 2^{1}=2, penny: 2^{0}=1

H H H = 4 + 2 + 1 = 7 (discarded- reroll)

H H T = 4 + 2 + 0 = 6

H T H = 4 + 0 + 1 = 5

H T T = 4 + 0 + 0 = 4

T H H = 0 + 2 + 1 = 3

T H T = 0 + 2 + 0 = 2

T T H = 0 + 0 + 1 = 1

T T T = 0 + 0 + 0 = 0 (discarded- reroll)

(For a d8 the TTT=0 is considered an 8, and none are discarded.)

Check out the examples below, then go roll dice like an MIT nerd.

Excellent!

And you can replace the other dice like D8, D12 up to D100 with some more coins. I'll improve this method with coloured plastic coins with 0-s and 1-s on their sides. Colours for the order, 0-s or 1-s for the binary value.

Congrats and Fhtang:-)!

o-o

woohoo, binary dice made from coins

*cough* (i knew how to do binary in 5th grade)*cough*

I'm NOT a geek!

=P

nice comment lol!

I knew binary in 4th grade!!! What Now!!!!!!

Erm... Not to brag.... I KNEW BINARY IN SECOND GRADE!!!!1!!eleven!!!111!!11!

not bragging...but i wrote a web page in 3rd grade. with html not webs.com

Ooh, big deal. I was programming in BASIC in the fourth grade. Real programming, not that spaghetti code bull most beginners write.

i was creating websites before i was born.
