    Happy grandkid with his CrunchLabs box for this month

    Just wanted to say thank you for making my grandson excited to get his CrunchLabs box delivery!

    He looks forward to it every month and asks every when it is coming every day.

    Too bad there isn't a daily delivery of a CrunchLabs box. :)

    Including a picture of him coming from the mailbox.

    Soccer game

    Every thing works except for the motor it’s really bad like in the video it’s not only really slow it gets stuck


    Hi Wade,

    I am so sorry to hear that the motor for your Galton's Goalie box is dysfunctional, please be sure to request a new motor through the complimentary replacement parts service in your account. If you should have any questions, please do not hesitate to reach out to

    Loved By Boy & Cat!

    Not certain who enjoys these more: my son and I while building along w/ Mark or the cat once the build is complete. Occupies both kids for hours.

Think Like an Engineer

"Thinking like an engineer means you’re resilient. It’s getting back up after being knocked down and approaching things differently. That determination helps kids tackle everyday challenges and it’s the same determination that puts rovers on other dang planets!" –Mark
