Getting a message that it will soon no longer work. ### 5/5 — Difficult to master *2018-05-10* This game is very difficult even with a strong command of the first 100 digits of Pi. I was disappointed when it ended at 100 digits. I mean, it’s Pi, guys. At least drag it out to 1000! Probably not the best way to LEARN Pi’s first 100 digits, but an excellent (and supremely dorky) way to sear them into your brain once you do. ### 5/5 — Fun & Educational *2015-03-15* Simple app teaches you pi as it challenges your speed :) ### 5/5 — Refreshing supercool *2015-03-14* Simple ideas are often the best and Pi Genius is one of these. Challenge yourself to learn Pi to more decimal places than you thought possible. The beauty of this app is in the clean, simple and intuitive aesthetic which is devoid of advertising banners, pop-overs or call to action buttons to mislead you into buying something else. Pi Genius is a reminder of how good iOS used to be; how they should be. A worthy addition to any iPhone home screen for those moments of downtime. A fantastic little app. ### 5/5 — Good Memory Challenge *2014-08-20* Cool simple app for testing your Pi nerd level! I'm only up to 13 digits, but I'll beat the world record soon enough! I like that there's no sales pitch for other apps - no ads or in-app purchases. Just my friend Pi and me! ### 5/5 — Learning + Playing = Awesome *2014-08-20* Super clean design. Fun to play. Definitely my new favorite game. My 10 year old son picked it up and hasn’t put it down. He’s actually memorized Pi out to 20 digits! ## Frequently asked questions about Pi Genius ### What is Pi Genius?
