ROKR 3D PINBALL GAME FULLY ASSEMBLED and OPERATIONAL. I purchased this puzzle for the challenge. It took a little over 20 hours of assembly with meticulous focus on preperation of each part. I love these types of challenges and seek to share these projects with others. Not all people have the desire or time to commit to such a project. For those I hope you enjoy my efforts. Keep watching for future puzzles for your consideration. Thank you and enjoy!
