Roogoo is a puzzle game that has you rotating concentric circular plates to align matching holes with falling shapes. You start off with three different shapes: A star, square, and triangle. Other shapes are added as the game progresses and each is a 3D piece that falls from one concentric circular plate to the next.

As the pieces fall through the plates they eventually stack on one another. Once several are stacked they begin falling again and you have to align them with yet more concentric circular plates. Once you've dropped all of a particular shape, the game then asks you to drop the next, until all of the shapes have made their way to the bottom-most concentric circular plate.

The game proceeds through multiple levels and as you work through it new game elements are introduced. So while you start out with a very simple tutorial, before long you are using the blocks to pop the Roogoo's enemies, the Meemoos, on the head, or rotating the concentric circular plates as butterflies take the pieces you worked so hard to get to the lower plates back up to the plates above them.

While the graphics are plain and simple, they are actually quite colorful. Sound effects are also simple, but are appropriate for the story and game play. Speaking of the story associated with Roogoo - a somewhat silly tale of the people of Roogoo and their journey back to their home planet - is told through static images and text.  Not that we'd expect an epic from any puzzle game, at least what's here isn't intrusive and doesn't intrude on the core gameplay.

Roogoo is simply a retelling of other classic puzzle games. Dropping pieces, alignment, and silly premises are all standard in such games, though it brings some originality and its own sense of style to the tired genre. And while Roogoo can definitely be challenging and rewarding to play, its low price ($10) is a sure indication that its target audience won't necessarily take it too seriously.
