About MemorisePi. Pi

MemorisePi is a free memory trainer for pi (3.14159265358979...), the ratio of a circle's circumference to its diameter. This page is the practice mode: the numpad path is hidden and you tap pi digits entirely from memory. Your score is saved locally between sessions.

Practice from memory. In play mode, the numpad path is hidden. You must tap each digit of the sequence from memory alone, with no visual guide. A correct tap advances the path; an incorrect tap triggers a brief error sound and a shake. Your score, the number of digits or primes you can enter without error, is stored locally so you can track progress across sessions.

Pi appears in geometry, trigonometry, physics, statistics, and engineering. Memorising its digits is a classic mental challenge and a popular competitive memory sport. Tap the digits on the on-screen numpad in the correct sequence. Use Study mode first to learn the path, then switch to Play to test retention. Hold the hint button to reveal the path briefly if you are stuck.

MemorisePi is designed for students, competitive memorisers, maths enthusiasts, and anyone who has ever wanted to rattle off more than 3.14. It runs entirely in the browser with no account, no installation, and no cost. Progress is saved locally using your browser's storage.
