Red Stone Puzzle

I created the The Blue Stone Riddle/Puzzle in 3D as a special gift for my brother, a great enthusiast of riddles and brain teasers. The goal of the puzzle is to fit all the rectangles, including the blue one, inside the box and be able to close it completely. This requires skill in visualizing spaces and finding the right combination to make all the pieces fit perfectly. It's an engaging challenge that tests problem-solving abilities and offers a rewarding experience once completed.
