The stars are already on the grid. Connect the ones that belong to the same constellation. The number on each row and column counts main stars, not every star in that line. In a constellation, the main star is the one at the top-left. After you connect them, the main star stays the same size. The others shrink. You work from the numbers. It feels like a logic puzzle. It is not Sudoku, and the shape is not given in advance.
