Make a Word

In this game you build words. You must take the previous word and make a new one. You do this by taking the letters in the word before and counting the letters in it. It should be less than 7. If the word is 7 letters, you use those 7 letters to create another word. If that word is less than 7 you still use 7 letters to create a word. You use the letters in the previous word and extra letters of your choice depending on how long the previous word is. If the previous word is 5, then you use those 5 letters and 2 of your choice because 5+2=7.You don't havew to use all your letters. But you have to make a word.The starting letters are "gochess"
