25+ Free Hour of Code Activities & Games for Kids (2024)

This year, Computer Science Education Week is taking place on December 4–10, 2023. Now is the time to celebrate! Break out the laptops, mechanical keyboards, iPads, or even pencils – whatever you’re coding with for these free Hour of Code activities.

What is Computer Science Education Week?

Computer Science Education Week (CSEdWeek) is an annual call to action to inspire K-12 students to learn computer science, advocate for equity in computer science education, and celebrate the contributions of students, teachers, and partners to the field.

What is Hour of Code?

The Hour of Code started as a one-hour introduction to computer science, designed to demystify “code”, to show that anybody can learn the basics, and to broaden participation in the field of computer science. It has since become a worldwide effort to celebrate computer science, starting with 1-hour coding activities but expanding to all sorts of community efforts. This grassroots campaign is supported by over 400 partners and 200,000 educators worldwide.

For organizations that are dedicated to coding and STEM education, this week is a time for us to introduce more kids to coding in a simple and fun way.

One of the best ways to participate is through Hour of Code. Spend one hour this week coding and see if coding is right for you. If you’re a teacher, organize an Hour of Code for your class. You can start with the activities below or get creative and create your own.

We’ve compiled some of our favorite free games and Hour of Code activities here for you. We have over 25+ Hour of Code activities, games, and tutorials for kids and teens of all ages. It’s never too late or too early to learn computer science and we encourage every child to try. These activities are beginner-friendly and easy to complete.
