OsoGo
The classic game of Os and Ss on squared paper: place O and S, complete OSO in any direction and earn an extra turn. With friends on the same phone or against the AI.
Connection and data
OsoGo runs entirely on your device: it has no server of its own, does not collect or send any data about you, and has no purchases. Your progress and settings are stored only on the device and are deleted when you uninstall the app. The trophy leaderboard is handled by Apple's Game Center with your Apple account, under its own policy. No accounts, ads or analytics.
