Problem of the Week

for Monday, November 9, 2009

Can you find a way to place the four pieces shown below (two L-pentominos and two F-pentominos) into the board so that there is no more room to fit any further pentominos? (That is, all remaining connected empty regions should contain four or fewer squares.) You can rotate and flip the pieces as you wish. The shaded squares are not to be covered. Good luck!
