An Escape Room puzzle by Ravensburger. Features a Greenhouse scene with a mystery to be solved. Has ALL 368 pieces, instructions, and the solution inside an envelope. The puzzle itself isn't too difficult, but the mystery is 5/5 challenging, and was very difficult for me to figure out. Pieces are slightly larger than standard, with a thick cut, and normal shape variations. This puzzle has ALL its pieces. This item has been used but is in excellent condition. I have personally assembled & inspected the puzzle to verify this.
