Unity Tutorial for Beginners: Make a Domino Game
Today you will learn how to make a Domino simulator game! You will learn how to create objects in the Unity editor, size and position them, and add components to your objects to give them realistic physics. Watch the video tutorial here if you prefer!
1. Create a New Project
Run Unity Hub. Click on the “Projects” tab on the left, and then click the “NEW” button. Type a name for your project, such as “Dominoes”, and click “CREATE”. This will create a project for your Dominoes simulator and automatically launch you into the Unity editor.
2. Create a Platform
Now that you are in the editor, it’s time to start creating objects! We will start by creating a horizontal platform for the Dominoes to stand on. In Unity, many basic shapes can be created directly from the right-click menu. Since our platform will have a nice, flat shape, we can base it on a Cube. Right-click in the background of the Hierarchy panel and choose “3D Object” and then “Cube” from the pop-up menu that appears.
3. Convert the simple Cube into a Domino Platform!
The Inspector Panel on the right side of the screen contains all of the information about whatever item you have selected. We can not only SEE the properties of a GameObject in the Inspector Panel, we can also CHANGE the properties! Make sure your Cube is selected, and then click into the Inspector Panel to change the name of your object to “Platform” and change the Position and Scale as you see in the following screenshot:
4. Create the first Domino based on a Cube
Now let’s practice what you learned before. Create another cube to be the basis for a Domino. (If you need a reminder, look back at Step 2!) The Domino will look similar to the Platform, except it will be tall and thin instead of short and wide. Make sure your new Cube is selected, and then click into the Inspector Panel to change the name of your object to “Domino” and change the Position and Scale as you see in the following screenshot. When you are finished, click the “Move” Tool button to prepare for next steps.
5. Give your Domino realistic physics!
Unity is built on an “Entity-Component” architecture. This means that all objects (“entities”) start the same, but by adding “Components” to them, they gain identity and functionality. For example, by adding a “Renderer” component, the object will now be rendered, or drawn, to the screen. By adding a “Collider” component, the object will now be solid and collide with other objects. We want our Domino to fall with gravity and to obey the basic laws of physics. We can accomplish all of that just by adding the “Rigidbody” component to our Domino!
6. Switch to 2D view and create our second Domino
Games often have many copies of the same or similar objects. In our Domino simulator, for example, all of the Dominoes will be exactly the same except for their position. Fortunately, Unity offers a convenient “Duplicate” option, so that we don’t have to recreate each Domino from scratch. To access it, right click on the original Domino, and then choose “Duplicate” from the pop-up menu. Let’s also switch to 2D view, so that it will be easier to position our new Domino next to the first one.
7. Move the Second Domino
When we Duplicated our first Domino, the copy was added to the world in exactly the same position as the original. Let’s move it so that it is in a good position to be knocked over when the first domino falls. We already clicked the Move Tool in Step 4. When the Move Tool is active, the selected game object will have Red, Green, and Blue arrows drawn on top of it. These arrows are called “Move Handles”. By (clicking and) dragging any of these arrows, we can move the game object along the X, Y, and Z axes, respectively.
8. Create a Domino chain!
Now it’s your turn to be creative! Using the Duplicate and Move skills that we have already learned, create a chain of Dominoes to tumble. You might choose to keep it simple, or you might choose to have many platforms and many dominoes. For an extra challenge, you can even add “Dominoes” that are different shapes, like spheres.
9. Get ready to tip the first Domino
It’s almost Go Time! If we press Play right now, we would see all of our dominoes standing, but not falling. Just like real life, we have to start our chain reaction by tipping the first Domino. To do this, we first switch to the Rotate Tool and select the first Domino.
10. Tip it!
The Rotate Tool works very similarly to the Move Tool, except that instead of drawing arrows, it draws Red, Green, and Blue circles. To rotate around the X, Y, or Z axis, we click on the circle and drag it. To tip our first Domino, we will click on the Blue circle and drag it until the Domino is tipped about 15 degrees.
11. Last step! Position the Camera to frame our Domino Chain
The view that the game shows when we press Play is determined by the Position and Rotation of the “Main Camera” object. This is not necessarily the same as the view that we see when we are editing the world. Fortunately, Unity once again has made it easy to sync up the Main Camera with the view that we have been using. We just need to select the Main Camera object in the Hierarchy Panel, and then use the “GameObject” Menu Item “Align With View”.
12. Press PLAY!
The Play button looks just like the Play button of a music player. It is located at the middle of the top of the screen. Click it, and see how your domino chain falls! Congratulations!
Get Creative: Customizing Your Game’s Look and Feel
Once your child has mastered the basics of creating a domino chain in Unity, it’s time to let their imagination shine. Unity offers a range of tools that allow kids to personalize their games, making them unique and visually appealing. Encourage your child to explore Unity’s Asset Store, where they can find free textures, materials, and 3D models to enhance their game.
For example, they could replace the simple cubes with fun, colorful dominoes or even themed objects like candy bars or books. They can also change the environment by adding a custom background, adjusting the lighting to create different moods, or experimenting with sound effects to add a satisfying “click” when dominoes fall.
Let them take ownership of their project by making design decisions that reflect their personality and interests—whether that’s making a rainbow domino chain, adding an outer space theme, or creating a whimsical fantasy world.
Building Problem-Solving Skills with Debugging in Unity
As your child creates their Domino game, they might run into challenges—like dominoes not falling as expected or objects behaving oddly. This is a great opportunity to introduce the concept of debugging. Debugging is a key part of game development and teaches problem-solving and resilience.
Encourage your child to troubleshoot by asking questions like, “Is the domino positioned correctly?” or “Did I apply the Rigidbody component?” Remind them that every mistake is a chance to learn, and that game developers often have to test, tweak, and refine their work.
Celebrate each small breakthrough as they figure out solutions—whether it’s adjusting the position of a domino, tweaking physics settings, or discovering a new way to achieve the effect they want. Debugging not only improves technical skills, but also helps kids develop a growth mindset as they learn that challenges can be overcome with persistence and creative thinking.
