Got a beautiful backyard perfect for gatherings? Here’s a nice little addition to your outdoor area!
Make your backyard even more fun by making an outdoor Tic-Tac-Toe game using natural elements – stones and wood, plus some paint.
It’s an easy and fun project even the young ones can do. But what we like more about it is that it’s very inexpensive to make, or even free if you happen to already have the needed supplies in your storage.
There are many possible materials you can use for the board. It could be a piece of scrap timber or plywood, some excess tiles or paving slabs, or even the top of a tree stump if you have one in your yard.
The ancient Romans actually played a variation of the game called “terni lapilli,” which means “three pebbles at a time.” They obviously used pebbles. The grid markings have been found chalked all over the paving slabs of Roman ruins!
That being said, you can be as creative as you want. Instead of simply marking the stones with X’s and O’s, why not paint something else – like red and yellow ladybugs or two types of emojis?
Have a look at a few DIY outdoor Tic-Tac-Toe games we found for you, and be inspired to make your own version!
Whether you want a classic wooden board or something a little more creative, these ideas are sure to inspire you. And the best part is, they’re all relatively simple to make. So gather up your supplies and get ready to have some fun!
Do you need one in your backyard? :)

Building an Outdoor Tic-Tac-Toe Game
You’ll need the following tools and materials to make a DIY outdoor Tic-Tac-Toe game.
- 14×8″ Board
- Dark Walnut Stain
- White Paint
- Outdoor Wood Sealer
- 10 Rocks

- Paintbrushes (large and small)
Steps:
This project is simple and inexpensive to make, and it’s a great way to get the kids (or grandkids) outside and play. All you need is a few pieces of supplies and some imagination. Here’s how to make your own outdoor Tic-Tac-Toe game:
1. Prepare the board
Prepare your 14×8″ Board. Trim and use sandpaper to smoothen the surface and edges.
2. Paint the board
Paint the board with a dark walnut stain. Let it dry.
To stain the board, first, use a dark walnut stain. Let the board dry completely before proceeding to the next step.
3. Draw the pattern
Draw 4 lines using the white paint to create the tic-tac-toe pattern. Let the paint dry before moving on to the next step.
4. Apply wood sealer
Apply wood sealer. This will help to protect the wood and ensure that the stain is even. Simply apply the sealer with a brush or cloth, and then allow it to dry completely before proceeding with the staining.
5. Clean and paint
Clean and paint the rocks that you will use to play on the board. Any design you want, probably two sets. then let it dry.
Make sure you clean and paint the rocks that you’ll be using to play the game on the board. You can design them however you want – probably two sets so that you have a backup. Once you’re done, let them dry.
Place a bowl for the painted rocks and let’s start the game! 
Best Outdoor Materials for Long-Lasting Tic-Tac-Toe Boards
Creating a DIY outdoor tic tac toe game is a fun project that adds charm and entertainment to your backyard. But if you want your game board to last, choosing the right materials is key. Weather, moisture, and sunlight can take a toll on outdoor games if they aren’t built to handle the elements. Here’s a guide to the best outdoor materials and protective finishes that will keep your tic tac toe game looking great and ready to play year-round.
Durable Woods for the Board
If you’re going for a wooden board, select a type of wood that resists moisture and decay. Cedar, teak, and redwood are great options because they have natural oils that protect against insects and rot. These woods hold up well outdoors with minimal maintenance. Pressure-treated wood is another choice, though it’s heavier and often needs additional sealing.
Whichever type you choose, make sure the wood is thoroughly sanded to remove splinters. Apply an outdoor wood stain to bring out its natural beauty and then finish it with a waterproof sealer. This will keep it safe from rain and sun damage.
Concrete or Stone Surfaces
For a heavy-duty option, consider using concrete or paving stones as your game board. These materials are naturally weather-resistant and require little upkeep. A flat concrete slab or large paver works perfectly. You can paint the grid directly onto the surface with exterior-grade paint or use a stencil for clean lines. To keep the paint from fading, add a clear masonry sealer once the paint has dried. If you have a tree stump in your yard, its surface can also serve as a rustic and natural board. Just make sure to sand it smooth and seal it to prevent moisture from breaking it down over time.
Waterproof Paints and Finishes
The paint you use makes a big difference in how long your game will last outdoors. Choose exterior acrylic paint or enamel paint for both the board and the playing pieces. These paints are formulated to withstand UV rays, rain, and fluctuating temperatures. Once the paint is dry, apply a coat of clear outdoor sealer. Polyurethane or spar urethane finishes work well on wood, while a concrete or masonry sealer is best for stone surfaces. These layers will prevent peeling, fading, and water damage.
Choosing Weather-Resistant Game Pieces
Painted stones are a popular choice for tic tac toe pieces because they’re easy to find and fun to decorate. Pick smooth, flat rocks and clean them thoroughly before painting. Use the same exterior paint and sealer you used for the board. If you want something lighter, you can use wooden discs made from treated lumber or sealed plywood. Another option is to use ceramic or glass pieces, though they may require extra care to prevent chipping.
Storage Tips for Extra Protection
Even with the best materials, proper storage can extend the life of your outdoor tic tac toe game. Store the game pieces in a waterproof container or bring them inside when not in use. If your board is portable, consider keeping it in a shed or under cover during harsh weather. Regularly check for signs of wear and touch up any paint or sealant as needed.
Choosing the right materials and protective finishes ensures your outdoor tic tac toe game stays in great shape. It will be ready for backyard fun whenever you are.

Giant Lawn Tic-Tac-Toe for Outdoor Parties
A giant lawn tic tac toe game is a simple, fun project that brings life to any outdoor party. It’s a crowd-pleaser for kids and adults, and it doesn’t take much time or money to make. You can create one using basic materials and enjoy endless rounds of friendly competition in your backyard.
This tutorial will walk you through the process of making your own giant outdoor tic tac toe game. We’ll cover everything from the materials you need to the step-by-step instructions to get it set up and ready to play.
Materials and Tools You’ll Need
Here’s a list of everything you’ll need to build your giant lawn tic tac toe game:
- 4 pool noodles (or rope, or thick string)
- 8 garden stakes or tent stakes (for securing the grid if using rope or string)
- Scissors (if using rope or string)
- Tape measure
- 10 large game pieces (you can use frisbees, bean bags, or wooden discs)
- Outdoor paint (optional, for decorating game pieces)
- Paintbrushes (if painting your game pieces)
- Permanent markers (optional, for marking the pieces)
- Storage tote or basket (for storing pieces when not in use)
Step-by-Step Guide
Step 1: Choose a Location
Find a flat area in your yard with enough space for the tic tac toe grid. Grass works best since it’s soft and makes it easy to stake down materials. Look for a space that’s free of rocks, holes, or uneven ground. This ensures everyone can play safely.
Step 2: Create the Grid
You can make your giant tic tac toe grid using pool noodles, rope, or string. Pool noodles are easy because they’re brightly colored and require no securing. If you’re using rope or string, you’ll need stakes to hold it in place.
- Using Pool Noodles:
- Lay out two pool noodles horizontally and two vertically to form a 3×3 grid.
- Overlap them where they cross, or cut small notches so they fit snugly together.
- You can also use garden stakes to pin down the ends if it’s windy.
- Using Rope or String:
- Measure and mark your area first. Each square should be about 2 feet by 2 feet, but you can adjust depending on the space.
- Lay down two parallel lines horizontally, about 2 feet apart. Do the same vertically to create the grid.
- Use garden stakes or tent pegs at the ends and intersections to keep the lines in place.
Step 3: Make the Game Pieces
You’ll need 10 game pieces—five for each player. They should be easy to spot from a distance. Here are some options for pieces and how to make them:
- Frisbees: Use two different colors. If they’re plain, you can mark them with a permanent marker.
- Bean Bags: Sew two sets of bean bags in different fabrics or colors.
- Wooden Discs: Cut 10 large circles from plywood. Sand the edges to make them smooth. Paint them with bright outdoor paint and let them dry. You can paint one set with X’s and the other with O’s.
- Painted Rocks: Choose 10 large, flat rocks. Paint them in two different colors or designs. Be sure to use exterior paint and seal them with clear outdoor sealer.
Step 4: Customize Your Pieces (Optional)
For a fun touch, decorate your game pieces with themes that match your party. For example, use stars and moons, ladybugs and bumblebees, or your favorite sports teams. Make sure the paint or markers are weatherproof if you want to use them again later.
Step 5: Set Up the Game
Lay out your grid on the grass and place your pieces nearby in a basket or tote. Assign players their pieces—one person gets X’s and the other gets O’s (or whichever designs you chose). You’re now ready to play!
Step 6: How to Play
The rules for giant lawn tic tac toe are the same as the classic version:
- Players take turns placing one piece at a time in an open square on the grid.
- The first player to get three of their pieces in a row—horizontally, vertically, or diagonally—wins the round.
- If all the squares are filled and no one has three in a row, it’s a draw.
- Collect your pieces and play again!
Step 7: Storage and Maintenance
When you’re finished playing, gather the pieces and store them in a container. If you used pool noodles or rope for the grid, roll them up and store them somewhere dry. Clean your pieces occasionally, especially if they’re painted rocks or wooden discs. Check them for damage and repaint or reseal as needed.
Conclusion
Making an outdoor tic tac toe game is a simple project that adds fun and charm to your backyard. With the right materials, it can last for years of enjoyment. Gather your supplies, follow the steps, and get ready for endless outdoor entertainment.
