Walk to a payphone, call my number, enter your PIN, capture it and score points. Other players can steal it and you lose points. Form triangles to hold territory. No app or no account. Covers the whole of Australia. I built it because a friend told me you could buy phone numbers for $2 and I wanted to put mine to use. I had collected the payphone dataset from a previous project (where you call into the payphone) so this was a good fit. Since covid, it's actually free to call out from payphones, so the game is completely free to play
