Birthday Heist on the Hillside (Majority Edge Piece Puzzle)

Putting together the edge pieces is usually the best part of a jigsaw puzzle. So what if (almost) every piece was an edge piece?

In this puzzle, 356 out of 538 pieces are edge pieces. That means no easy starting point—just a beautifully maddening challenge, where every piece is as tricky as the next.

Who is stealing things from the birthday party? Dig deeper and you'll discover a hidden world of ants.
