[This review was collected as part of a promotion.] Absolute in love with Theo super addictive toy!!! My kids are hooked to it and it keeps them Busy for a long amount of time. Very interesting not just for kids but for adults too!! Such a fun way to spend time with kids and be kids ourselves!!

[This review was collected as part of a promotion.] so this was not so much fun for my 8 year old. she doesn’t have the attention span to focus on building it however my teen loved it. once it b was put together they enjoyed it. my 8 year old loves watching the marbles. that part actually kept her attention for quite some time

It will be cool when it’s done. It just takes hours of assembly. I bought it for my 6-year-old son but I’d say it’s more for 9 and above.
