Pick a window of the building to play on
Your game keeps running while you read.
Each piece is one colour. The rare wild pane matches any colour.
Touching side by side or up and down. More than 8 is fine.
Your game is on the building, on the window you pick. It lights up in its colour, then goes dark from the top: 3, 2, 1. Your phone shows the same number and colour.
The game ends when there is no room for a new piece, or after 5 minutes. Quit (top left) ends it early. It asks first.
If your connection drops for a moment, you keep your place.
