Easy — logic-grid deduction puzzle
At a rooftop drone workshop the wind scattered the instructor's notes, and now nobody knows who flew from which mat, what they photographed, or which filter they used.
On a bright afternoon, a community photo workshop met on a rooftop to try taking pictures with drones. The launch mats sat in a row along the edge of the roof, in order from mat A to mat D, and each pilot claimed one. Each pilot picked something different to photograph: the fountain, the mural, the bridge or the skyline. Each one also clipped a different colored filter onto the camera before takeoff. The instructor scribbled notes as the drones went up, but a gust of wind grabbed her pages and blew them across the roof. All that's left is a handful of scraps. Can you put the afternoon back together?
