Pentominoes are shapes that use five square blocks joined edge to edge to form various combinations. There are twelve possible shapes in a set of unique pentominoes, named T, U, V, W, X, Y, Z, F, I, L, P, and N.
Pentominoes are said to have been "invented" by Solomon W. Golomb.
Try to fit your pentominoes together in 6x10 board.
