Memorise Primes with muscle memory
PlayMemorize is a tool for memorising prime numbers (ℙ = 2, 3, 5, 7, 11, …). Each prime is its own numpad sequence. Instead of recalling the number, you recall a gesture. Trained through repetition, the same way your fingers learn a PIN or a chord. Enable sound from the menu to also build melody memory: each digit plays a unique musical tone.
It works on any device, but performs best on a phone. With enough repetition, the primes become a sequence of movements rather than numbers.
Read the complete Major Pincode System guide →How to learn
Study. Browse all primes with their numpad paths pre-drawn.
Learn. The prime digits are shown. Tap them in order and watch the path reveal itself.
Play. No digits shown. Tap from memory alone. Hold hint to see the path.
Memory lives in your fingers, not your brain. Use them.
