I found a fun game for you (http://type.method.ac/).
Your mission is simple: achieve pleasant and readable text by distributing the space between letters. Typographers call this activity kerning. Your solution will be compared to a typographer's solution, and you will be given a score depending on how close you nailed it. Good luck!
They are the actual instructions of this game. I think, it is a great game.
We as designers, we have to deal with typography in our work, so this is a great game to challenge your kerning sense.
