  • How to create and work with clones
  • How to add sounds
  • How to send the game to your friends

What you will need


  • A computer (with either Windows or macOS) capable of running Unity


Unity! These Sushi Cards are for Unity version 2017.1, so if you have a different version, the pictures and some of the instructions here might not match exactly.

title: How to get Unity

  • Go to and click on the Download Installer button.

  • Run the installer program once it’s downloaded, and follow the on-screen instructions, accepting all the default options.

  • Wait for the download and installation steps to complete.

  • Once the Unity software is installed, you will need to create an account (or sign in if you already have one). This is so that you can access the free version, which is for personal use.

Additional resources

  • Download the starter project from This has all of the assets you need to create a game with these Sushi Cards! You won’t need to make your own new Unity project, because this creates a project for you.

  • You will need to unzip the file you downloaded and open the project in Unity. Feel free to rearrange the layout of the various tabs and screen areas to suit you!

Messages pop up when I try to open the project

Depending on which version of Unity you are using, you might see a message like this when you open the project:

Popup message about non-matching editors

Also, depending on what operating system you have, you might get a message like this:
Popup message about the build target

I want different assets than the ones in the download

You can download different assets and use them to change what your game looks like!
