Numberblocks Treasure Hunt

Review by eFreeware

Numberblocks Treasure Hunt is an educational game from Blue Zoo, the animation studio behind the Numberblocks series, and it turns early number practice into a pirate voyage. You pay $5.99 once, and the app contains no ads and no in-app purchases. For a parent who has watched a child latch onto the television characters, that combination is the main reason to pay attention.

The pitch is straightforward: sail to Hexagon Island, train the Numberblocks through six games, and collect treasure along the way. It is a game rather than a worksheet, and it is built around number sense, which the developer describes as the foundation for mathematical fluency. That framing tells you the audience is young children at the start of their math education, not older kids drilling times tables.

A pirate voyage built around the Numberblocks

The setting does a lot of work here. Captain Hexbeard, described as a rascally pirate, has buried treasure across Hexagon Island, and the journey to find it is told through animations made for this app. Fans of the show will recognize the characters, while the pirate framing gives the whole thing a goal beyond finishing a level.

Gold, Diamond and Crystal are the three adventures. Each one features different Numberblocks, so the choice is not just cosmetic; it changes which characters a child spends time with. That gives a family some room to pick a route based on which Numberblocks their child likes best, and it also means there is more than one pass through the island's content.

The educational side comes from a studio that works with early-years experts, and the app is described as designed by educational experts and experts in play. Blue Zoo is a BAFTA-award-winning animation studio and the creator of Alphablocks, Numberblocks and Colorblocks, so the production values are likely to match what families already expect from those shows.

Six games, one skill at a time

The core of the app is six games, each one aligned with a different number-sense skill. The developer says the games are new and built to teach and reinforce those skills rather than simply entertain. A child moves through them as part of the island journey, so practice is wrapped inside the story instead of presented as a separate exercise.

A typical session, based on how the app is structured, would have a child pick an adventure, meet the Numberblocks involved, and work through challenges tied to Captain Hexbeard's treasure. The six challenges are the spine of the experience; completing them is what moves the treasure hunt forward. Along the way there is a section on the Numberblocks' Clubs, where the app tests what a child has picked up.

There is also a feature called More to Explore, which takes the ideas off the screen and into the real world. That is the part I find most interesting as a parent-facing idea: it gives an adult a way to extend the number talk beyond the tablet, using everyday objects and situations. It is the kind of addition that makes a paid children's app feel less like a closed loop.

Treasure, certificates and reasons to return

Earn a share of Captain Hexbeard's treasure by completing six challenges, with Number Explorer certificates too. Certificates are a small thing, but for a young child they turn a completed run into something to show an adult, which is often what brings them back for another adventure.

The three adventures, each with its own cast of Numberblocks, are the other reason to replay. A child who finishes Gold can start Diamond or Crystal and meet a different set of characters, so the content is not exhausted in a single sitting. The narrative journey and its animations give that repetition a context, which matters when the audience is at an age where repetition is how learning sticks.

The app was released in December 2023 and last updated in June 2026. That is a modest update note, but it does indicate the app is still being maintained rather than left as it shipped.

What it costs and what you get for it

Numberblocks Treasure Hunt is a one-time purchase of $5.99. There are no ads, and there are no in-app purchases, so there is nothing else to buy once you have paid. The developer also states that the app is COPPA and GDPR-K compliant and that personal information is never shared with third parties or sold.

That model is worth weighing against the free alternatives many families use. A paid app with no ads and no purchases means no interruptions during play and no requests to spend more, which is often exactly what parents are looking for in this category. The trade-off is that you pay before you know whether your child will take to it.

The app holds a 3.3 average from 66 ratings, with more than 5,000 installs. That is a small sample and a middling score, so it is worth reading the reviews rather than treating the number as a verdict. The content rating is Everyone, which fits the intended age group.

A narrow fit, and that is the point

This app is built for a specific child: one who is learning early number skills and who already knows and likes the Numberblocks. The pirate theme, the characters and the certificate rewards all point in that direction. If that describes your household, the pieces line up well.

The six games are focused on number sense rather than a broad curriculum. That is a deliberate choice, and it means the app is best understood as a supplement to what a child is learning elsewhere rather than a complete math program. Parents looking for a single app to cover many subjects will find this one narrower than that.

The $5.99 price and the absence of ads and purchases make the decision simple: you either want a paid, self-contained Numberblocks adventure or you do not. The choice comes down to how confident you are that the characters will hold your child's attention.

A sound buy for young Numberblocks fans

Numberblocks Treasure Hunt is a well-defined product: a paid, ad-free pirate adventure that uses the Numberblocks to practice early number skills. The six games, three adventures and certificate rewards give it more structure than a typical collection of mini-games, and the More to Explore section offers a bridge back to the real world.

I would suggest it to parents of children who are just starting to build number sense and who already enjoy the show. The one-time $5.99 cost, with no ads and no in-app purchases, keeps the experience clean, and the studio's background in early-years education is a reasonable signal of quality. The 3.3 average from 66 ratings is worth a look before you buy, but for the right child this is a straightforward purchase.
