Android Giveaway of the Day - Chemistry - Dropping Ions Game

The Dropping Ions Game will help you practice and remember the charges on the most common chemical ions in a fun way. In the game, tiles with the ion symbols fall from the top of the screen and can be moved right or left. You must maneuver the tiles such that a row of five tiles have a combined charge of zero. Whenever a row is completed, it disappears, making room for more rows of tiles.

You can compare and add your scores to a top scores table.

There are a number of options to adjust the game's difficulty which include whether the dropping ion symbols include the ionic charge and whether the present sun of the charges in each row is shown.
