LEGO Unicorn Castle (31175): Worth ₹4,549?

A castle, a rainbow unicorn, or a treehouse — the Creator 3-in-1 Unicorn Castle (31175) gives you three builds from one box, all leaning hard into pink, purple, and glitter. The three-in-one format is usually great value; the question here is whether 390 pieces is enough to spread across all three.

The main build, the unicorn castle, is surprisingly detailed for its piece count. It features a rainbow archway, a small tower, and of course, a unicorn. The colours are vibrant, leaning heavily into pinks, purples, and blues, which will appeal to a specific audience. It’s not huge, but it has enough charm to be a display piece, especially if you’re into fantasy themes. The unicorn itself is well-constructed, with posable legs and a majestic horn. The inclusion of a rainbow adds that extra touch of magic, completing the fairy-tale aesthetic.

Then there’s the alternate build: the unicorn with a rainbow. This is a more straightforward build, focusing solely on the creature and its colourful arc. It’s simpler than the castle but still captures the essence of the unicorn. This build might appeal more to those who want a standalone unicorn figure rather than a full structure. The posability is still there, allowing for dynamic display options. It’s a good option if you prefer less scenery and more creature focus.

The third option is the magical treehouse. This build shifts gears entirely, moving from mythical creatures to a more grounded, albeit still fantastical, woodland setting. It includes a treehouse with a slide, a small pond, and some woodland animals. This offers a completely different play experience and aesthetic, showcasing the versatility of the Creator 3-in-1 line. It’s a smart way to get more value out of the limited piece count, offering something for everyone, or at least, three different somethings.

However, the piece count for the Unicorn Castle is only 390. When you consider the price of ₹4,549 from LEGO.in, that’s roughly ₹11.66 per piece. For a Creator 3-in-1 set, especially one aimed at younger builders, that feels a bit steep. Creator 3-in-1 sets are often praised for their value and re-playability, but this one borders on being overpriced for what you get. The builds are decent, but they don’t feel substantial enough to justify the cost. It feels like you're paying a premium for the unicorn theme and the multiple build options, rather than a high piece count or complex design.

The builds themselves, while charming, are not particularly complex. Younger builders will enjoy the process, but experienced builders might find it a bit too simplistic. The colours, while fitting the theme, can also be a bit overwhelming, and not everyone is a fan of such a strong pink and purple aesthetic. If you’re buying this for a child who specifically loves unicorns and rainbows, they will likely be thrilled. If you’re looking for a more general-purpose building set or something that offers significant complexity, you might want to look elsewhere. The versatility is its strongest point, but the price-to-piece ratio, combined with the niche theme, makes it a cautious buy.

In India, the LEGO Unicorn Castle (31175) is available at LEGO.in for ₹4,549 and at Toycra for ₹4,999. Use code ABHINAV12 for 12% off on orders above ₹500 at Toycra, bringing the price down to ₹4,399.20. That’s 11 months of Spotify Premium or enough to buy 18kg of fresh Alphonso mangoes. LEGO.in and Toycra are the stores to watch.

The set is fun, no doubt about it. The three builds offer variety, and the unicorn theme is popular. But the price-to-piece ratio is a significant drawback. You can find larger, more intricate Creator 3-in-1 sets for a similar or lower price per piece. It’s a good set for a specific fan, but for the general builder, it might be worth waiting for a sale or a price drop — and at ₹4,549, it already has: about 9% under the international MRP. If the unicorn theme appeals at all, there's no reason to wait further.

Keep building, keep dreaming... And don't let your wallet see your LEGO wishlist.

Correction (3 October 2026): an earlier version of this review gave the wrong piece count and price-per-piece figures worked out from it. Both now match the official count.
