Retailer reviews
Summarized retailer review data when available.
Lego Mario is interactive and easy to build using the app. This is clearer than just following instructions in a booklet. You can also play with individual sets or combine them all together.
Very nice addition to the Mario collection!
It is wonderful, educational material for children. Good for fine motor skills and for imagination.
That it can be a very fun and educational game!
My son is happy with it, but I think it's an expensive LEGO set for what you get. The LEGO Mario (and therefore this addition) doesn't encourage building new things as much as other LEGO sets.
My children have now also received the "Haunted Garden" set after the "Guarded Fortress" expansion. This was high on their list due to the "spooky" theme. The 6.5-year-old was able to build it independently, taking about 3 hours. As with all Mario LEGO sets, the instructions are not on paper but only via the app. There are some elements from Technic LEGO in it, which is very well done. Using gears and a rotating mechanism, you can make King Boo fall out of the tower so that you can defeat him. Once completed, they found it a bit disappointing. It doesn't, of course, exude the cheerful Super Mario atmosphere like the other sets. There is less action in it than in the "Guarded Fortress", and the structure also seems smaller and offers less space for your own creativity. 4 rotating bats, 2 goombas, identical towers... a lot of the same. Ultimately, they are all beautiful sets that complement each other, but if you had to choose one from this price range, I would (initially) choose the "Guarded Fortress". It also offers more possibilities to restructure your level, together with parts from the starter set.
