About: Student at UH Manoa. Maker. Surfer. Learner.

Hello everyone, I hope you’re doing great. This is my first Instructable in a while, I'm excited to get back in the game. I'm going to share how I made this Tic-Tac-Toe game using stones from my backyard. It should be a fun weekend project. Enjoy!

Step 1: Tools & Materials

This is a very cheap and simple project. I decided to order my cotton bag off Amazon but I'm sure there are many more local and cheaper alternatives to this.


  • 1 Black Chisel Tip Sharpie
  • 1 Pencil
  • 1 Fine Detail Paint Brush
  • 1 Measuring Tape / Ruler


Step 2: Gather & Clean Rocks

  1. Draw a square 1.25" x 1.25" on a piece of paper. Use it as a size guide when choosing rocks.
  2. Keep collecting rocks until you have 10.
  3. Wash rocks with water and soap.

Step 3: Draw the Board

  1. With a pencil, draw lines at one-third of the width and length of the bag.
  2. Draw over pencil lines with a chisel tip permanent marker.
  3. Let it dry.

Step 4: Paint Rocks

  1. Separate your rocks into two piles.
  2. Paint "X" on five rocks. Paint "O" on five rocks.
  3. Let the paint dry.

Step 5: Play!

Grab your stones and play! When you're done you can store them in the bag and take them anywhere. This is a great game for picnics, camping, and game nights with family or friends.

Let me know if you try making it, I would like to know what you think. I hope you enjoyed this Instructable, I had a great time making it. There are many more coming soon!
