Infinite Numbers vs Gomoku

∞ Numbers is a quiet offline game about integer sequences. Guess integer sequences drawn from the On-Line Encyclopedia of Integer Sequences (OEIS). Your job is to guess the next number. How it plays. Tap a row, look at the first few terms, type your guess on the numpad. When you've had enough, tap Reveal to see the real name of the sequence and references to OEIS and Wikipedia. Made for calm play. No ads. No accounts. No in-app purchases. No ranking or leaderboards. The app never touches the network after install — every sequence is bundled with the app, and the only "internet" is the moment you tap a reference link to open a browser. Designed to disappear. No analytics, no notifications, no permission prompts. Nothing asks for your location, contacts, microphone, camera, or anything else. The only data stored anywhere is the in-progress state of your own game, kept locally on your device. You can wipe it any time from iOS Settings. For who. Math hobbyists, puzzle fans, kids and parents looking for a screen-time option that isn't loud, and anyone who's ever read an OEIS page for fun. Sequence data from the On-Line Encyclopedia of Integer Sequences (oeis.org), CC BY-NC 4.0.
