Ralph's Killer Muenster for iOS

Ralph's Killer Muenster is a puzzle game that challenges you to try and unscramble the escaped muenster's genetic code to stop its spread. Neighborhood by neighborhood, you have to make alterations to one shape to make it match the other and solve one more link in the muenster's genetic sequence. Only when all of the matches have been made will the city finally be safe.

When you open the game, you'll see a short animation that depicts a delivery truck for Ralph's Killer Muenster driving through a city on a dark and rainy night. The driver loses control and crashes, sending some of the muenster out the back of the truck and down into the sewer. Once it gets into the sewer, it mutates and begins spreading throughout the city. Your goal in the game is to stop its spread and help neutralize it by turning the mutant strain back into the original strain, one neighborhood at a time. To do this, you have to make the two shapes you are presented with look the same by altering one characteristic of one of them at a time. The shapes and accompanying characteristics get more and more complex as you go, and you want to try and complete the match in as few moves as possible to keep advancing.

The tutorial for this game is clear, and the interface is intuitive. It's a fun puzzle game that starts out easy and gets more and more challenging as you move through the levels. If you're looking for a new free game with some unique twists, this is a good one to try.
