About
How many digits of π can you remember? StockloPi turns memorizing pi into a game – one digit at a time, with music, stars and a cosmic glow.
THE JOURNEY
100 stages, 10 digits each – 1,000 digits across 10 chapters. Every stage has four steps: See the digits play as a melody, Echo them with ghost hints, Recall them on your own, and Chain them together with the previous stages. Earn up to three stars per stage.
GAME MODES
• Marathon – start at "3.14" and go as far as you can. Three lives.
• Sprint – 60 seconds. Build combos for up to a x5 multiplier.
• Free Practice – start anywhere, like the Feynman point, and choose your level of hints.
• Pi Rain – catch the right digits as they fall from the sky.
• Pi Snake – steer the snake to the next digit of π.
PI SOUNDS LIKE MUSIC
Every digit is a note on a pentatonic scale, so π becomes a melody when you type it correctly.
STAY MOTIVATED
XP and levels, daily streaks, achievements such as the Feynman Point and Pi Time at 3:14 pm, statistics that show your tricky spots, and Game Center leaderboards.
No ads. No account. No data collected. All 10,000 digits are computed with Machin's formula and verified.
