Featured Puzzle: Arukone (Number Pairs) #4

A traditional gift for Valentine’s Day is a bouquet of flowers, usually roses. Rather than gathering a bunch of identical flowers, I thought it would be more interesting to match up pairs of flowers. Connect each pair of identical flowers with orthogonal paths.

• Lines run horizontally or vertically, and may travel straight through a square, or turn 90 degrees.
• Lines may not pass through flowers, or cross another line.
• No more than one line may pass through any cell.
• A line may not cover a 2×2 area, whether by U-turn, or passing itself.
• All cells will be used.
