This is a solution for a 5 x 5 game submitted by James Aaronson. You only need to flip all the pieces marked with a star in the following picture:
The solution is quite easy to remember. You should start by flipping the first two pieces on the first row, then scan the pieces row by row, and if a piece is black, simply flip the piece directly below it.
James has also suggested the following strategy for playing the game: first flip random pieces on the first row, then scan the pieces row by row, and if a piece is black, simply flip the piece below it. If this doesn't work, start again by flipping a different set of pieces on the first row.
