A specialized screw is inserted through the top of a block and turned 90 degrees to firmly connect it to the block below, creating a strong, stable structure. This system ensures the model is simple to build, aesthetic, sturdy, and fun.

Troubleshooting
Should you encounter any issues during assembly or with your finished model, refer to the following common solutions:
Missing Pieces:
Carefully re-check all packaging and sorting trays. If pieces are genuinely missing, contact JEKCA customer support with details of the missing parts (as per the printed manual's part list).
Difficulty Interlocking Blocks:
Ensure the specialized tool is used correctly. Pins should be inserted straight and turned as instructed. Do not force pins; if resistance is met, check alignment of blocks and pins.
