Leadlight

Every dot shows a number. That number is how many lines it needs — no more, no less.

Draw lines between dots until every number on the board is satisfied. The rules are the whole game, and there are only two: a line may never cross another line, and a line may never pass through a dot it doesn't end at. Everything else is you, the board, and the quiet.

100 hand-verified puzzles across ten trails — Dawn Circuit, Prism Garden, Tidal Archive, Ember Causeway, Aurora Loom, Moonlit Relay, Verdant Current, Solar Foundry, Starlight Delta and Crown Confluence. Each trail has its own colour chapter, and the boards get hotter as you go.
