Flip-Side???

[CanadaCube]

I just purchased a Flip-Side and It is a Great Puzzle!!! It is basically 10 tiles in 2 Rows. You Can Slide The Rows individually and in the centre, Is a wheel where it flips 3 numbers from the top row and 3 numbers from the bottom row. I recommend that you get one and try it out!

Agreed. It is not very hard, but it takes a while untill you get it. Then it becomes easy
