The Enigma Puzzle is a sequence of riddles played in the same way as other games like it: Each of its 34 levels—with another 16 levels soon to be added—presents an HTML page with clues that you must use to figure out how to get to the next one. Use any tool at your disposal, including a text editor, graphics program, calculator, media player, and especially your browser's View Source function. The game was designed and created using Windows and IE, so beware there may be a puzzle or two that requires that forsaken browser. The riddles have logical solutions and are a ton of fun to solve. And while each page may appear to be a separate puzzle from the rest, there are many riddles that build upon ideas or techniques that were introduced earlier.
