geoSpark, the collaborative effort between Imangi Studios, the creators of Harbor Master, and Critical Thought Games, the creators of geoDefense Swarm, has just landed in the App Store.

The concept behind the game is relatively simple.  All you have to do is match like “Sparks” by tapping and dragging them into each other. You can drag multiple Sparks into each other to create chains in order to gain large score bonuses, but you must be quick and nimble when matching them because if two unlike Sparks run into each other, the game is over.

geoSpark features an art style commonly used in Critical Thought Games’ iPhone games, and it also features the casual pick-up -and-play gameplay that is often used by Imangi Studios.  The game is also integrated with OpenFeint, which means you can show off how good or possibly bad you are at guiding Sparks.

geoSpark is now available in the App Store for $.99.
