Another 15 question review game is done. This one is about factor market (Monopsony and Perfect Competition). You can find it at the bottom of the "Monopsony/Perfect Comp" page under "Failures and Factors."
All of the Games and activities are in adobe flash format so they will not work on Android or IOS. There is an Android Economics Review App available in the google play store and I hope to make an IOS game sometime next year.
