How to play

1Choose one of the six categories.
2You have 20 seconds for each question. Tap an answer, or press 1, 2, 3 or 4.
3Each correct answer adds one to your streak. The questions get harder as you go: easy at first, medium from question 7 and hard from question 14.
4One wrong answer, or running out of time, ends the run. You then see the right answer and a short explanation.
5Post your streak to the daily and weekly leaderboards with a nickname and a country flag.

Is PiRush free?: Yes. It is free to play, with no account and nothing to download.
Who is it for?: Anyone who enjoys math: students, parents, teachers and puzzle fans of every age. The first questions are easy, so everyone can start a streak.
How does the leaderboard work?: After a run you can post your streak with a nickname and a flag. The daily board starts again every day at 00:00 UTC, and the weekly board every Monday at 00:00 UTC.
Can I play in Spanish?: Yes. Use the EN / ES switch at the top of the page. Every question and every explanation is translated.
Where do the questions come from?: Every question was written for PiRush, and every answer was checked twice.
Who makes PiRush?: The team behind PiRush, a free educational YouTube channel about math puzzles and surprising ideas.
