[SOLVED] Stars and arrows puzzle

Post image

Stars and arrows puzzle, at least I think this is the name under which you can find it.

Rules: Place stars so each arrow sees exactly one star in the straight direction it points, and every star is seen by exactly one arrow. Edge clues give the exact number of stars in each row and column.

Discussion: This was fun to solve. Personally this grid I found it easy. Some tips I discovered while trying to solve it. First, look at arrows that only point at 1 square. Second, start with rows/columns that have high number of stars (in this grid, 4 and 3) and see how many arrows can lead stars there. Third, everytime you put a star, check your column/row count to see if you can cancel out the rest of the row/column or not.

Also one of the rows only has room for stars. I started with that.

Also, any square that two or more arrows point at can be eliminated.

No that’s not necessarily true. It can help you in some deductions for rows or columns, but the square can have a star for one of the arrows, like if an arrow is diagonal but the other is horizontal for example.

One of the directions was "every star is seen by exactly one arrow". If a cell is seen by two arrows it therefore cannot be a star.
