The object of the game is to slice through the correct word as is moves across the board. Points are earned to help you become a "ninja". There are three different levels of difficulty (easy, medium, hard) and you may set the game to last anywhere from one to ten minutes. As the game goes on the words are presented faster and faster. There are five levels, from Kindergarten to third grade. You can also set it for random playback of words or not.  
This is a great app! Teachers can choose from 50 words at each grade level for practice. The app can also be set to read the words aloud so the students will hear the correct pronunciation. You can set this up as a center for your students using the words that you are currently teaching or words that have been previously taught to check for retention. In the same or following center you can set up a writing lab asking students to write simple sentences using the words they just learned.
