I'll try an explain how the game works.
You are presented with a word, for example 'perlmonksisgreat'.
You have to try and make words from this using only the letters that are in the word, you can only use each letter as many times as it appears. In the above example you could use 1 x 'p' and 2 x 'e' and so on.
Some examples of valid words are 'perl', 'slop', 'term'.
An example of a non-valid word would be 'pepper' (only 1 'p').
