I can certainly appreciate an app that incorporates a pun in its name (and I hope you can, too). Take, for example, the Oresome Elements app, a periodic table and game all-in-one that is aimed to teach students the atomic symbols. In addition, this particular periodic table includes the nice touch of providing examples of where one might find each element. (For instance, vanadium is found in metal springs, while germanium is used in electronics). The game component of the app is simple, as it has users simply drag floating bubbles labeled with atomic symbols onto their appropriate spots on the periodic table. There is a built-in help (or rather, answer) feature that allows users to tap on a square of the table to reveal the correct symbol corresponding to that element. The game is divided into three levels, with each level bringing in additional squares of the periodic table.
