Getting started
Tap Begin, choose an available username or Play Offline, and reduce each augmented matrix using Swap, Add, and Scale. The level clears when the matrix reaches reduced row echelon form.
Row Echelon
Support
Help for the Row Echelon matrix puzzle game on iPhone and the web.
Offline play and saved progress
Offline mode has no inactivity timeout and saves progress on the device. Online username profiles save puzzle progress and participate in the daily leaderboard. Internet access is required for online profiles and rankings.
Sound or music is missing
Confirm sound is enabled in Settings, raise the device media volume, and make sure the iPhone is not muted. If audio does not recover, fully close Row Echelon and open it again.
Username or session problems
Usernames are case-insensitive and may already be active on another device. Online sessions expire after 30 minutes without activity. Ending a session releases it; offline sessions do not expire.
Leaderboard information
Daily points reset each day. Profiles with zero points are not displayed. A player's lifetime solved total remains with the username.
Before reporting a problem
Note the app version shown in the lower-left corner, your iPhone model and iOS version, whether you were online or offline, and the steps that caused the issue. Never share a session token.
