Rox is a falling block/matching game, but with a twist. Each of the blocks is a Rox which has a number on it. Instead of only matching colors, in this game both the colors and numbers matter.
In order to remove Rox two end numbers must be the same, with that amount of other Rox in between them. For instance if two Rox are ones, there must be one Rox in between them. If both of the end Rox are the same color, all of the Rox in between will also be erased, however if they are two different colors than only the end Rox will be erased.
Gameplay involves rotating and arranging the falling blocks to create chains of matching numbers and colors. As the game progresses, the blocks fall faster and the player must react quickly to make matches before they disappear.
