#1: Pong | 20 Games Challenge

Not much to say... it's Pong! This first game in the challenge was a great way to reset to the fundamentals, and to experiment with a first form of basic CPU.

• Divider
• Ball physics and logic with Rigidbody
• Collision handling
• Dynamic UI on screen

What is the 20 Games Challenge?

In early 2026, I found out about the 20 Games Challenge. It's a fun challenge designed by SDG Games to recreate 20 games in an engine of your choice. The premise of the challenge is that, by copying a masterpiece, artists often gain a deeper understanding of the fundamentals behind their craft. This can also apply to game developers and game designers.

I was sceptical at first, but as someone who's obsessed with figuring out how things work, this challenge had some huge appeal. So, in March 2026, I decided to give it a try: I'd attempt to recreate 20 famous games in about a year!

The 20 Games Challenge is fairly guided for the first 10 games, then free for the rest. Each level requires you to complete a set of steps in a vertical slice to consider it done. If you want to attempt it too, you can see options for the first 10 levels on this page.
