I found an extra bunch of letter tiles in the back of my closet during my spring cleaning, so I created this little language arts game called Mystery Word. The rules are simple. They build each word next to the word, and with the letters that are left, try to make a real word out of it. I've included the first two word lists here as a freebie to get you started!
(Edited to add, the link should work now. Thanks for bringing it to my attention!)
