"Unlike most learning game apps, Stick Around is open-ended; it isn't limited to the content it comes with. Stick Around is all about empowering teachers and students to make puzzles with their own information, images, and drawings. Stick Around can be used over and over again for just about any topic or grade level. "

It looks like an app that has way more potential that a cursory view gives away - Download it now and give it a try. It appears to be deeply integrated with Explain Everything, so depending on the use of that in your course, some really neat stuff could be created!
Note: It is only available for free December 15 and 16.
