Numberblocks: Hide and Seek

Review by eFreeware

If you have a preschooler who already knows the Numberblocks characters from television, this is the app most likely to land well in your house. Numberblocks: Hide and Seek takes the same cast and turns them into a simple hunt-and-add game, with no advertising and nothing to buy once you have paid the $3.49 asking price. For parents who want screen time that stays inside the Numberblocks world, that combination is the main draw.

The developer, Blue Zoo, is the studio behind the show's animation. The app carries an Everyone content rating and has been downloaded more than 50,000 times. Its average sits at 3.4 from 703 ratings, which is a middling score for a paid children's game, so it is worth going in with a clear idea of what the game does and who it is built for.

What it is built for is narrow and deliberate: addition, number bonds and recognizing quantities at a glance. This is not a general early-learning package with letters, shapes and songs bolted on. It drills one area of early math through play, and the whole experience is organized around getting to ten.

A park, a cast of characters and a hunt

The premise is hide and seek. Numberblocks poke their heads out around the scene and your child taps them to bring them into play. Once two have been found, the game moves into its central trick: dragging one Numberblock on top of the other to start what the developer calls number magic.

Each successful addition is meant to be predicted first. The game asks the child what will happen when the two numbers combine, and if they are not sure, they are encouraged to guess. That guess-then-check rhythm is the part that turns a tapping game into something closer to arithmetic practice. It also gives you, as the adult nearby, an easy opening to ask why they picked a particular answer.

The setting gives the whole thing a destination. Every time the child reaches Ten, an animation plays and a new interactive plaything appears in the park. The park fills up as they go, which gives the sessions a visible shape rather than an endless stream of sums.

How a round actually unfolds

A typical session follows a fixed sequence. Your child taps the hidden characters as they appear, gathers two of them, and then drags one onto the other. To make the addition happen, both Numberblocks go into a white shape on screen, and the result plays out as an animation. Then the hunt continues, with the new total added to the next find.

That loop repeats until the running total reaches Ten. Hitting Ten is the payoff moment: an animation celebrates it, and something new shows up in the park to play with. The child is not just collecting numbers, they are building toward a small reward each time.

The difficulty is not fixed. Later rounds bring tougher sums and fresh number shapes for the Numberblocks. That progression matters for a game aimed at this age group, because it means the same activity keeps offering something slightly beyond what the child has already mastered rather than staying at a level they outgrow in a week.

There is also a fallback for children who get stuck. If a Numberblock's shape looks unfamiliar, the suggestion is to count the individual blocks that make it up. That is a nice piece of design, because it turns a moment of confusion into the counting practice the game is trying to build anyway.

Why the park keeps children coming back

The collectible structure is what gives the game its length. There are 20 playthings to discover in total, and once all of them have been found, the game can be restarted from the beginning. Repeated play, the developer says, builds number bonds and the skill of guessing which blocks will combine.

That is a reasonable argument for a math game. Repetition is how these facts become automatic, and a child who has already filled the park once will move through the early sums faster on a second run, which lets them focus on the harder combinations later on.

The new number shapes serve a similar purpose. Seeing amounts as patterns rather than counting one by one is the skill the game is quietly building, and the changing shapes push children toward recognizing quantities on sight. The counting fallback is there for when a shape does not click immediately.

An SDK update in August 2026 shows the app is still maintained, though it adds no new content.

One payment, no interruptions

The cost structure here is about as simple as it gets. The app is $3.49 up front, it contains no advertising, and there are no in-app purchases. For a children's game, that means no banner interrupting a five-year-old mid-sum and no prompt asking you to unlock something.

You are paying for the whole thing on the strength of the characters your child already knows. Given the 3.4 average from 703 ratings, some families have clearly found the game less satisfying than the show it is based on, so it is worth weighing that before buying.

The upside of the one-off price is that the game does not need to keep selling to your child. There is nothing to grind toward and nothing gated behind a purchase, which suits the short, supervised sessions this kind of app tends to get.

A focused fit for Numberblocks households

This is a game for families already inside the Numberblocks universe, ideally with a child around preschool age who is starting to add small numbers. It suits short sessions with an adult nearby, partly because the predict-then-check step works better when someone is there to ask questions, and partly because the reward of a new park plaything gives the session a natural stopping point.

It is less suited to anyone looking for a broad early-learning app. The scope is addition and number bonds, delivered through one repeating loop, and the game assumes some familiarity with the characters and their block shapes. A child who has never seen the show may still enjoy the hunt, but the appeal is clearly tied to the brand.

At $3.49 with no ads and no purchases, the risk is low and the value is straightforward if the app suits your child's level. The middling rating suggests it will not charm every household, but for a family that wants ad-free addition practice built on characters their child already loves, it is an easy thing to try.
