Negative Positive
Title: Awesome
Review: I found them to be just perfect for a mind break. Total concentration was needed to solve them and allowed my mind to put aside other things for a time. No extensive set up time is needed, nor is a large part of a table needed to be dedicated for extended periods of time. In the space a placemat would take up, you move the squares around till it's solved and in under an hour you have a total mind vacation. One of the best parts is that after having them put away for a time I can take them out and solve again, enjoying the same challenge as the first time.
