Every street tells you how many lanterns are burning and how much smoke is rising. It's up to you to work out which. No timer, no luck — just a grid and its logic.
The marker on the edge of a tile tells you how many lanterns must burn on that street. No more, no less.
Every unlit lantern leaves a wisp of smoke. That second count is often the key that unlocks the grid.
Every grid has a unique solution, reachable by logic alone. No guessing required.
