It is not keyboarding practice the way we learned as 6th graders, Drop Typing appeals to the Minecraft generation. In fact it was created by Markus Persson, the original Minecraft guru. This addictive touch typing game is full of optical illusions and music. It does require the unity web player download, but it runs on Mac OS, Windows and Linux. As you type, the blinking letters drop off the screen., but if you hit the wrong key the game speeds up and stops completely if you are typing too slow.
