Not all games are about shooting stuff or overthrowing violent warlords. Puzzle titles are more about the inner struggle the human need to think quickly, decipher daunting riddles and top past performances. Puzzlers encompass everything from guiding blocks down a narrow shaft to form perfect lines to wrecking entire armies with pinballs. The games are made for all ages and the best examples of the genre are those that are easy to learn but impossible to master.
