The city has gone dark
For fifty years, Grandpa Idris lit every lantern in the city by sending domino chains through its streets each night. Now he is too old, and his firefly friend Nour asks you to take over.
- 1
Place the pieces
Drag the missing dominoes from the tray into the dashed spots.
- 2
Turn them right
Tap a piece to turn it, so the chain can pass from one domino to the next.
- 3
Push once
Tap the glowing domino and watch the chain run. Every domino that falls plays a note.
- 4
Light every lantern
All lit with one push is three stars. A miss? Reset the chain: your pieces stay where you put them.
The chain follows exact grid rules, never luck, so every puzzle is fair and every miss shows you something.
