Like the familiar number version, the rules for solving these puzzles are simple:
Put one--and only one--of the music symbols given in

• each row
• each column
• each 3x2 box that's within the bigger grid

This set of six-square puzzles includes three levels of difficulty--easy(*), medium-easy(**) and medium(***). Each puzzle is labeled accordingly and the puzzles get progressively harder as you move to the end.

None are as challenging as the nine-square puzzles, though, which makes them perfect anytime you're on-the-go and find yourself not going. You'll want to keep this in your purse, briefcase, bag, or music tote, because once you start, you won't be able to stop.
