Summary: In Musaic Box you'll need to find sheets of music in an eye-spy game and then you'll have to solve optical and acustical puzzles to hear the right tune played. I never like eye-spy work but I really enjoyed the puzzle part. The songs are quite simple childhood songs - I guess for copy-right reasons and to make sure everyone knows what the solutions should sound like to make the puzzles a bit easier. The puzzles usually aren't tough to solve but always fun.
Summary: This is a very simple music based puzzle game with an eye spy front end. The mechanics are done well, but the game lacks any significant puzzle complexity. The musical pieces include familiar classical tunes...Old MacDonald, Twinkle Twinkle Little Star, Auld Lang Syne, etc...pretty boring stuff. Keep your expectations low and you won't be disappointed spending five quarters on it, but you can play this on the web as a free java game all the same.
