Video Games in Mathematics II

Couldn't think of anything else with the Wii U so I've been looking at apps on the iPad. One of the apps I came across is terrible so I'm not even going to bother mentioning it here, but the following app "My Equation" isn't so bad:

There's just no followup besides having students pick the correct sign. It's not timed either...There's absolutely no extension, meaning that students will get bored after 5 minutes with the game (just like I have).... On second thought...It is quite bad.. I'll continue to update until I find some solid games.
