A detailed approach how to break Playfair can be found here, basically it tries to analyse the frequency of the letters which is of course harder when blocks are substituted instead of single characters. It ﬁnds each letter in the matrix, determines each letter’s row and column numbers, then rearranges those numbers to make new row and column numbers, then looks in the matrix again to ﬁnd the corresponding letters. A digraph is transformed by looking up the two characters in the grid. Below you can find the calculator for encryption and decryption to play with.
