How to make a 3D game

To make a 3D game, kids add height to a flat map: mountains stand up, lakes dip down, and the camera decides whether you see a map or a 3D world. In this course your kid builds a real island adventure on a baking tray, with paper squares for land, cups for mountains, a boat to escape, a hidden key, and a grumpy crab for a villain. Tek hosts four short films. Plan about 4 minutes of films and 45–60 minutes of building and playing.

All 4 films and the quiz are free on this page. Your kid doesn't need an account. See every lesson

What your kid makes

Your kid ends with a three-island adventure on a tray: a start and a boat, then a hidden key, then a villain, played in order with the family. The same ideas are the ones game makers use on screen.

The 4 lessons

  1. Lesson 1. Height makes it 3D

    A 3D world has height, and where you look from is called the camera.

    1. Lay paper squares on a tray for the land
    2. Add a start, a boat, and one tall thing
    3. Look from the top, then from the side

    Where: Paper

    Watch it at the top of the page

  2. Lesson 2. Walls make the path

    Mountains, a lake, and a house block the way, so the hero follows one path.

    1. Put walls between the start and the boat
    2. Leave exactly one way through
    3. Walk the hero along it and count the steps

    Where: Paper

  3. Lesson 3. Lock the boat

    A key hidden off the easy path makes the player explore.

    1. Build a second island
    2. Draw a paper key and cut it out
    3. Hide it away from the easy path, and let a grown-up play

    Where: Paper

  4. Lesson 4. Add a villain

    A villain patrols a loop or chases the hero, and there's always a safe way past.

    1. Build a third island with a villain
    2. Pick patrol or chase
    3. Play all three islands with the family

    Where: Paper

Lesson 1 transcript: Height makes it 3D

  1. Hi, I'm Tek! Today you build a 3D game world. A whole island, right on your table!

  2. A 3D world has one more thing. Height! Mountains stand up tall, and lakes dip down low.

  3. Grab a tray or a box lid. Cut paper squares for the land. Cups and boxes make mountains!

  4. Every island needs two things. A start, where your hero begins. And a boat, the way out!

  5. Now look from the top. It's a map! Look from the side. It's a 3D game! Where you look from is called the camera.

  6. Your turn. Build your first island. Add a start, a boat, and one tall thing. Look from the top, then from the side. Then press Next.

Questions parents ask

Does making a 3D game need a computer?

Not for this course. Every lesson happens on a tray with paper, cups, and a toy. The ideas are the ones game makers use on screen: height, walls, a key, and a villain.

What age is this for?

Kids 6 to 13. Younger kids may want help cutting the squares and the key. Older kids can design harder islands on their own.

Is the villain scary?

No. The example villain is Snap, a grumpy crab who guards the beach. Getting caught only costs a heart and sends the hero back to the start.
