Featured Puzzle: Number Chain #2

I enjoy various path puzzles, and Number Chain is an interesting one. Your goal is to find the route from the upper left corner to the bottom right corner of the grid, traveling only up, down, left, or right.

• The path must contain exactly one of each number within the range shown by the start and end cells. (In this case 1-31)
• The path may only travel in orthogonal directions.
• Numbers within the range are not necessarily in sequence.
