Memorise Tau with muscle memory

PlayMemorize is a free tool for memorising Tau (τ ≈ 6....). It uses the Major Pincode System: each group of six digits becomes one numpad shape your fingers learn, and one three-image story your mind holds. The shape and the story are locked together from the first tap. Enable sound to add a third anchor: each digit plays a unique musical tone.

It works on any device, but performs best on a phone. With enough repetition, the digits become a sequence of movements rather than numbers.

Study. Browse all 100 six-digit sequences with their paths pre-drawn.

Learn. The 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.
