This is an easy to make Yahtzee game to fit in your pocket. It takes a few origami folds but can be made in minutes.

Step 1: Materials

You will need the following.
Scissors
Tyvek
Markers (For decorating)
A paperclip
Yahtzee sheets from http://www.memory-improvement-tips.com/yahtzee-score-sheets.html (Make it come out four on a sheet for them to be small.)
5 Dice
Pencils/Pens
A pencil sharpener (If using pencils)

Sorry for having no pictures for this part.

Step 2: Get Tyvek

If you know how to make an origami cup you can skip to step 6 , if not.
Cut the Tyvek to a decent size.
If using it from a envelope put the words up so you wont see them after folding.

Step 3: Make a Triangle

Fold the corner to the edge to make a triangle. Cut off the extra.

Step 4: Fold in the Corners

Take the corners and fold them straight back. Each on different sides. (Do not fold it to the bottom! Fold straight across!)

Step 5: Tuck the Flaps

Take one of the corners sticking out and tuck it into the pocket beneath it. (The picture will help describe it.) Repeat on the other side.

Step 6: Stock It Up!

Get 5 normal sized dice, or smaller, and put those in the cup.
Then find some small pencils or pens and a sharpener (if using pencils) and throw those in too.
Then get some Yahtzee sheets from this site http://www.memory-improvement-tips.com/yahtzee-score-sheets.html and press the button to print four on a sheet. Then, cut them up nice, fold them up,and put it in.
