The main problem is to match the tabs along certain sides with the corresponding holes of adjacent pieces. It’s fairly easy to fit the 10 all different pieces into the tray with 6 holes left over. The 6 holes can go toward the edge or, more challenging, all in the center. Not every pattern you can imagine is possible though! We really recommend the pattern puzzles for longevity as you can always really see new variations as you solve the puzzle in different ways and invent your own patterns. This one is highly recommended.
