That's Puzzling

 When Tori and Jordan were going through the trunk in the attic, they found a number of puzzles and asked their grandma about them. She told them that her grandparents used to leave puzzles around the house for her mom and her uncle. Whoever could solve all the puzzles first could choose a chore that they did not have to do that day, such as washing the dishes or folding the laundry. Your great-grandmother loved to get out of chores, so she was very good at the puzzles.
