" Review: Web Instructions are the way to go! - The print instructions aren't bad by any means, but it was a little challenging to figure out which rod to use where given they're all the same color. There was a small piece of paper tucked in the book that provides a link for troubleshooting. I took a look-it sends you to a video that does a good overview of building the model and making it work well. More importantly, in the video description there's another link for updated web instructions that include extra letters and numbers that really spell out what to use where in each step. I had the instructions up on my laptop and printed out the slip sheet to organize the different rods-worked like a charm! Great build, lots of fun, and a good amount of support material-would definitely recommend to anyone young or old that likes to build or tinker! Review: K'NEX is now in the marble game! - I've always been a fan on K'NEX since the 90s and loved the original ball factory. This new marble coaster set really does a good job continuing that legacy of fun, educational building sets. It does have a motor, it's built from all classic K'NEX, and introduces new marble parts and pieces which are super cool and fun! I really hope K'NEX turns this into a line like their micro coasters-would be really cool to collect and combine into a giant marble coaster run or make a marble coaster run amusement park! ## Features - 500+ PIECES – This epic building set comes with over 500 pieces, including 3 accordion tubes, a see-saw marble scoop, and a bankshot bounce pad that will really add some WOW to your coaster! - MOTORIZED MOVEMENTS – Experience the excitement of watching your Marble Coaster Run come to life with the battery-powered motor that keeps the fun going! - STEAM LEARNING FUN – Building with K'NEX helps strengthen fine motor skills, manual dexterity, and spatial relations.
