Pi Game - Memorise 100 Digits

Pi Game - Memorise 100 Digits of Pi

What is Pi Game?

Pi Game is a little game I made, to help you memorise the first 100 digits of Pi. I made it in one weekend, so don't expect too much.

How does it work?

There are two lines full of numbers. But they are mixed up.  Click them in the correct order (of Pi) from left to right. Here's an image explaining it visualy:

(Click the numbers in the correct order (in this case 3.1415926))

But how does this game help you memorise the digits? If you get something wrong, you can restart. You will need to restart plenty of times at first, but over time you'll memorise the digits because you press them over and over again. It takes time.  Some tips: Say the numbers out loud as you press them. The game is divided up into "blocks", there is a limited amount of numbers for you to memorise at a time. Once you've got most of them (except one) correct, repeat them (e.g. in the image above you'd repeat "3.141592" multiple times). This will make it easier for you to memorise them.

Can I play the game on my phone?

Yes, you can. Clicking on a computer with your mouse is technically the same as tapping a number on a phone. Because clicking / tapping is the only control in this game, you can also memorise Pi on the go on your phone, by playing it in your browser.

IMPORTANT INFORMATION REGARDING UNITY VULNERABILITY
In October 2025 a critical security vulnerability (CVE-2025-59489) was found regarding all versions newer than 2017.1. Unity released a patching tool for Windows and Mac. I patched the game on October 3rd 2025 using the patching tool. Unfortunately Unity did not release a patching tool for Linux. In order to patch the Linux Build, I would've needed to update my unity version, with a high risk of corrupting the game files, in order to build it again for Linux. For me, this was not worth the time and risk. Therefore the Linux file was not patched. If you still want to run the game on Linux, consider using the Windows file and running it using WINE or Proton. Use the unpatched Linux file at your own risk! https://unity.com/security/sept-2025-01/remediation According to Unity, the HTML Browser version is not vulnerable.
