Six‑cess is a flat acrylic packing puzzle by Rex Rossano Perez that uses six yellow jigsaw‑shaped pieces and a blue rectangular frame. The goal is simple to explain—fit all six pieces inside the frame—but the solution is far less obvious than it looks. The shapes force you to rethink your placement and try different combinations before everything finally settles into place.
Made from durable acrylic and measuring about 159 × 96.5 × 5 mm, the puzzle is slim, portable, and easy to bring along for quick solving sessions. Its moderate difficulty makes it approachable while still offering a solid challenge, especially for fans of packing puzzles. Six‑cess delivers that classic “it looks easy until you try it” experience, making it a fun and replayable addition to any collection.
