Pi Clicker vs Idle Marathon

A game about digging out what comes after 3.1415... Tap to earn compute (OPS), research algorithms to automate it, and spend your OPS to decode the digits of pi (π) one at a time. Decoded digits pile up on screen, and each one makes your computation a little faster. ■ Research real algorithms Gregory–Leibniz series (1671), Machin's formula (1706), Monte Carlo (1949), FFT multiplication (1971), Chudnovsky series (1988) and more — researching real algorithms speeds up your computation. Each one comes with a short explanation, its formula, and references. ■ Pi digit tape Read back the digits you decoded as a full-screen table. ■ Recomputation Hit a wall, commission a new machine, and start over from 3.14. You keep a permanent bonus based on your deepest verified digit, so each run goes faster and deeper than the last. ■ Milestones from history Archimedes's polygons, Shanks's hand computation, ENIAC's 2,037 digits — each depth you reach decodes another piece of history. ■ Idle-friendly Computation continues while the app is closed. ・CRT terminal pixel UI (font: DotGothic16) ・28 Game Center achievements, 3 leaderboards ・English / Japanese ・No ads, no in-app purchases, no data collection

An around-the-world marathon that runs itself. Your runner keeps running while the app is closed. Open it now and then, give him water, spend the coins he earned. Simple to play, with more to it than it looks. ■ Run 191 countries, one after another You start from your own country, run to the next one, then the next. All the way around the world, until one day you come home again. ■ Collect a badge for every flag One badge for each country you reach, 192 in all. See how much of the collection you can complete. ■ New scenery with every arrival City, suburb, forest, coast, mountain, desert, snow. The weather and the time of day shift as well. Built so that simply watching him run is part of it. ■ What you do is simple Give him water to restore stamina. Spend coins on Speed and Stamina. Raise your runner and send him on to the next country. ■ Can you make the target time? Every destination has its own time limit. Make it and you earn the badge; miss it and he runs the same leg again. Either way, you never lose the distance or the coins. The kind of game that is just nice to check in on. ・No account or sign-up required
