Sightlines
Count the dots you can see past every wall.
How to play Sightlines
Numbers count the dots visible in the four straight directions, excluding their own square. Walls block the view, and every dot must see at least one other dot. Play with the original Nickelbar rules and board drawings. Help below the game lists its keyboard and mouse shortcuts. Your current game stays in this browser tab.
- Click a square to cycle dot, wall and empty.
- Use numbered clues to decide where dots and walls belong.
- Fill the board consistently. I offers a hint and S changes size.
