Type the digits of π that come after “3.” from memory. In Ranked mode one mistake ends the run. Practice lets you keep going and use hints, and Learn shows the digits ahead.
Only your personal best counts. A country's score is the sum of the best scores of everyone who plays from that country. The daily ranking resets at 00:00 UTC.
We store the name you enter, your scores, your country (estimated from your connection — we don't store your IP address) and a random ID saved in this browser. No sign-up needed. Records that look automated and inappropriate names may be removed.
