Go! Puzzle

Go! Puzzle or Swizzle Blocks(as it is alternatively called) is mash-up of a number of classic puzzle techniques. Starting with a partially-full board of blocks, your goal is to match up four same-color blocks into a square to get rid of them. If any other blocks of the same color touch this square when it's removed, they too are phased out in to oblivion. The Swizzle part of the name is taken from the act of spinning them -- the blocks spin, or swizzle, on a point that lies between four blocks. It's possible to spin a single block around a point, which allows you to actually move it across the screen. The game doesn't use "gravity" of any sort like some other puzzle titles, so blocks can be separated at the top and bottom of the screen and you can then simply swizzle them together.
