Puzzle 178: Times Zone

David Millar of thegriddle.net came up with a neat new type recently with Times Zone. It’s a hybrid of latin square and loop puzzle, where the numbers inside the loop (in the “times zone”) form products while the numbers outside form sums. Check out the Intro to Times Zone for detailed instructions and a walkthrough. Here’s one I made, enjoy:

Rules Fill the grid with digits 1-6, so that each row/column contains each digit exactly once. Furthermore, draw a single loop along the grid lines that doesn’t touch or cross itself.

The loop divides each row/column into groups of digits. Each such group of digits corresponds to a number; it’s the product of these digits if the group is inside the loop, and the sum otherwise. Clues outside the grid describe the groups in that row/column in the correct order; an asterisk (*) stands for an arbitrary amount of groups, including no group at all.
