Gridy Tiles Puzzle

Gridy offers a revolutionary concept in puzzle game design that will challenge your ability to plan ahead like chess masters. Its simple rules make it easy to play and fun. The game play makes it challenging and addictive. Starting from a grid of red and green tiles, your goal is to turn all tiles green. But you can only switch tiles in a shape you place on screen at once. That is, all that is green becomes red and all that was red becomes green in that shape. Very simple rules! Only that you have to be very art and figure a way such that you flip the tiles in a logical way to end up with a clean board of just green. Easy as pie! (or is it?)If at this time you are wondering how you should pronounce the name when telling your friends about this amazing logic game, just simply think of greed (not the best strategy, maybe) and you end up with Greedy :)
