Large set with different designs, works okay
Penny✓ Verified Purchase•October 17, 2023
This large marble run took a couple of adults about 45 minutes to put together, using the instructions and a mat that shows where the legs should go. There are other easier designs possible that are quicker to build and take fewer pieces. Once it's built, there are "action" pieces that spin, make jumps for the marbles, or reroute the marbles. The set comes with enough marbles for several people to play with the run at one time. When the areas where the marbles land get filled up, they will spill out onto the floor. When the tracks get out of alignment, the marbles don't land right from the jump and that can be frustrating. After it is set up and working, it is fun, then disassembling it is much quicker, but getting it all back into the box is a bit of a challenge. This would not be a good set for kids who get frustrated easily, or for parents who don't like making a mess and getting marbles all over the floor.
Great toy but instructions are infuriating
Shantel✓ Verified Purchase•September 27, 2023
I love this toy, we still enjoy it regardless of poor instruction. Once you get the idea on how to assemble it it'll go by like a breeze but the instructions and app only came with pictures and when you're dealing with over 300 pieces that can be overwhelming. If the pieces were marked with a number or letter that would have made this toy perfect !
Great set for my 12 year old
Timothy Moody✓ Verified Purchase•September 21, 2023
I really enjoyed this set for my son. He can put it together in many different ways, the instructions are a little challenging for a 12 year old, but in all is a great marble run set.

poor instructions

You will need to go to their website for directions which is a pain. Once you understand how the pieces work, it's not that difficult. My 10 Year old was able to build with it.
