Review on 🎢 ROKR Marble Run Wooden Puzzles: Engaging Hands-On Fun! by Christopher Shavers

This is the fifth bullet run I have collected from this company and I have to say it was the most rewarding, albeit challenging, even for someone who has made several of these models. The key to a successful build is patience, patience, patience, and very careful study of the circuits at each step. There are some components that only need to be attached in a certain way, and sometimes the only clue is in the shapes drawn. I only did one or two sections a day to avoid being rushed as this particular model requires careful fitting of the pieces due to the less bulky material. TIP: Gently sand down the tabs that fit into the corresponding slots, but don't overdo it! Also apply wax to the slots where the two parts interlock. Use only thumb and forefinger pressure to bring the pieces together. There were a few spots where the connections were a bit loose and I had to use super glue to hold them together. take your time! I like the complexity of the different routes the balls go through, it raises it to a higher level than the previous ones.
