About this game

Blue dots see other blue dots along their own row and column, while red dots block the view. A numbered dot tells how many it can see, and every blue dot must see at least one other. Those visibility constraints guide the grid solution.

Objective

Resolve the grid to satisfy each visibility clue.

Progression

Choose a grid size and reconcile numbered rows and columns.
