### Round Trip

**Round Trip** is a kind of logic puzzles. The aim is to draw a single loop in a rectangular or square grid. A loop may cross itself orthogonally, but otherwise does not touch or retrace itself. The numbers along the edge of the puzzle indicate the number of cells visited by the nearest section of the loop in corresponding row or column.

**Cross+A** can solve puzzles from **4 x 4** to **30 x 30**.
