3. Operating Instructions
Assembling a jigsaw puzzle involves patience and strategy. The Trefl Prime puzzles feature Unlimited Fit Technology, which means the pieces are designed for a precise fit, reducing false fits and enhancing the overall experience. The unique, irregular shape of the pieces and the thick cardboard construction contribute to a high-quality feel.
General Assembly Tips:
- Sort Pieces: Begin by sorting the pieces by color, pattern, or edge type. Separate all edge pieces to build the border first.
- Work in Sections: Due to the large number of pieces, it is recommended to work on one 1500-piece section at a time, as indicated by the lettered bags.
- Use the Poster: Refer frequently to the included poster for visual guidance on colors, details, and overall image composition.
- Connect Sections: Once individual 1500-piece sections are completed, carefully connect them together following the layout provided in the instructions and on the poster. The Unlimited Fit Technology allows for easy movement and rotation of assembled sections.
- Lighting: Ensure good lighting to clearly see the colors and details of each piece.

- Keep the puzzle box for organized storage of pieces and the reference poster.
Cleaning:
- To clean puzzle pieces, gently wipe them with a dry, soft cloth.

5. Troubleshooting
While Trefl puzzles are manufactured to high standards, occasional issues may arise. Here are some common concerns and their solutions:
Missing Pieces:
- Thoroughly check the puzzle box, packaging, and surrounding area. Pieces can sometimes stick to the inside of the bags or box flaps.
- If a piece is genuinely missing, contact Trefl customer support with details of your puzzle and the missing piece's location (if identifiable from the poster).
Pieces Not Fitting:
- Trefl Prime puzzles feature Unlimited Fit Technology for precise connections. If a piece doesn't fit, it's likely not the correct piece for that spot.
- Double-check the shape, color, and pattern against the surrounding pieces and the reference poster.
- Ensure the piece is oriented correctly.
Damaged Pieces:
- If pieces are damaged upon arrival, please contact customer support for assistance.
