An idea for a minigame category: The Magic Letter

My zany mind just came up with another zany 2:00-in-the-morning idea. This time, instead of being for a Wheel element like the ones you'd see on my Wheels of Stuffness, it's for a puzzle category, The Magic Letter. The story of how I came up with this idea as well as how it works can be seen below. I know it's completely luck-based and may make for a rather quick round, but I just wanted to give this concept a try.

Check it out, and let me know what you guys think.
