Threads is a simple game of steering an expanding line without colliding with other lines or borders. Play solo against the computer or together, either up to 4 players on a single device (inconvenient) or up to 16 players on individual devices connected to the same local network, using WiFi capability.
Set game speed, number of CPU players, CPU behavior and other settings to adjust game play and difficulty.
Note that network game play performance is highly dependent on a reliable and fast network connection and a responsive device that during game play doesn't have to share its resources with other demanding applications.
UPDATE 2016-08-31: Local network play does not work well on Android version 5 and above (which didn't exist at the time this app was made and tested). An updated app will be published later when the problem is found and fixed.
