I suggest you trying a very funny game called 

"The Spelling bee".

A spelling bee is a competition where contestants, usually children, are asked to spell English words.

You know that it's very difficult to spell the English words as there aren't exact rules. The links which are given below will help you to master spelling skills. Don't forget to write comments and share your results and impressions.
