Hello, I've been searching games for learning touch typing for a long time and the best I've found until now is
Typing of the Dead for PC. It's an oldie but it has good graphics, good sound, good story and best of all, good learning and drilling. Students can practice all keys in the keyboard. With its complete progress chart, it's never been so funny to type. It's full of action. I think is good for all competitive students of mechanography but I recommend the game for older students because it has some soft "language" and violence.
