**Turn a 6-sided dice into an 8-sided dice**

Yesterday I gave a way to roll a 6-sided dice one time and generate a random number from 1 to 8.

Today I will tell you how to roll a 6-sided dice and generate other numbers (where the odds of rolling any of the possible numbers is along an equal distribution).

**Turn a 6-sided dice into a 12-sided dice**

With a 6-sided dice, you can generate a number from 1 to 12. There are two methods. The first is easier than the method for making your 6-sided dice act like an 8-sided dice (and it is shorter to explain).

*Method 1:*

Roll the dice and notice that you see three faces — the one on top, and two side faces. If the face to the left is odd, then add 6 the value you rolled (the top face). If it is even, then the value you rolled is the value. This means you get values from 1 to 12! Note: If you only see one side face (because the dice is squarely facing you), then turn the dice slightly to the left and now you see another side face.

*Method 2:*

There are 12 edges to a cube. That means there is a more complicated way to get these same results as given in Method 1. Using a system not unlike the one I gave for an 8-sided dice, you can uniquely identify each of the 12 edges by *multiplying the two numbers that touch each edge*. I’ll let you generate the values on your own. The look-up table to map those results back to the numbers 1-12 is unwieldy, so I suggest using Method 1.

**Turn a 6-sided dice into a 5-sided dice**

I wrote about this after I wrote this post. Read about it here. This is real easy: roll the 6-sided dice, and when you roll a six, just roll again till you get a value between 1 and 5.

**Turn a 6-sided dice into a 4-sided dice**

I figured this one out after I wrote this original post. Read about it here.

**Turn a 6-sided dice into a 2-sided dice**

This may be easiest of all. If the number is odd, you rolled a 1, it if is even, you rolled a 2.

**Turn a 6-sided dice into a 3-sided dice**

Only slightly more complicated then the last one: 1, 2 and 3 stay the same. But if you roll a 4, 5, or 6 then map those back to 1, 2 and 3.

**Why?**

Someone might be interested to do this if they play Dungeons and Dragons or some other role playing game that requires different kinds of dice. They might also invent a game, and they want to use a random number generator besides the standard 6-sided dice which is widely available. Almost every home has a 6-sided dice in it somewhere, so having these other options can be handy.
