If I had an engineering degree I still wouldn’t be able to follow these instructions. Absolutely impossible to follow.

The instructions don’t match the picture. The actual parts don’t match the picture. It is actually impossible to build what is depicted on the box. The worst. Do not buy this marble run!

Absolute worst instructions ever. This makes ikea instructions look good. Which I thought was impossible. Don’t recommend unless you want every adult in your house frustrated and ready to yeet it out the front door.

These instructions are absolutely impossible and way too vague. I have never struggled so hard to put something together. It's been two solid hours. Do not buy unless you enjoy torturing yourself for hours. Someone please send me wine.

Very flimsy pieces, difficulty level is a 10 definitely WOULD NOT recommend!! I had to tape the pieces and even then they used it once and it fell apart…horrible product..not worth the money.

This took forever for my husband to put together. Just like the other reviews, it’s extremely flimsy and the instructions are trash. It falls apart while trying to piece everything together. Even once he put it together it fell apart within 5 minutes of play. Save your money and time.

The worst instructions I’ve even seen in my entire life. My 4 year old is so disappointed that it’s not working. Especially after 4 hours trying to put it together, with mom and dad!

Absolutely TERRIBLE instructions! Kids - and adults - were in tears over our inability to put it together. Even an engineer couldn't figure this out let alone a 4 year old. Worse toy I have ever purchased.

The absolute worst! Paid for a headache and only minutes of fun before packing it up to return it. Also false advertisement as not all 3 possible chutes work simultaneously; you can only have two working at the same time. Worst instructions I’ve EVER seen. Target should cut ties with this manufacturer/distributor.

Horrible instructions that make no sense. Save yourself the headache!
