Play the blackout
Walk a message across a crowd and watch nearby phones carry it onward. Try nine short levels and a sandbox to see how Knit keeps people talking when the cell network is down or overloaded, including the kilometre-long hops an optional Meshtastic radio adds.
Level 1 of 9
A normal Tuesday
The way messaging usually works
Priya is across the park. Send her a message the way you always do, and watch where it actually goes.
Tap the map to walk there, and tap a phone to see what it is carrying. Drag the map, or hold the arrows in the corner, to see what is past the edge.Click the map to walk there, or steer with the arrow keys. Click a phone to see what it is carrying, and drag the map to see what is past the edge.
Send Priya a message over the internet.
Nine short levels, about eight minutes. Or skip straight to free play and break the mesh yourself.
The real thing lives on your phone
Knit relays messages phone to phone, holds them when nobody is in range, and needs no tower, server or account to do it — exactly as it did here. The map is the simplified part: one phone hop stands for the few tens of metres a Bluetooth or Wi-Fi hop really covers. Direct and group chats are end-to-end encrypted, so the phones relaying for you cannot read them. The Meshtastic radio and the Internet relay in the last few levels are real features too, and both stay off until you switch them on: a radio adds a hop measured in kilometres, and a relay carries only conversations you already started. Requires Android 10+.
