Numberblocks: Hide and Seek - A Counting App Built for Little Hands

By Nham Vu · Updated July 2026

Numberblocks: Hide and Seek is a mobile counting app from Blue Zoo, the same studio behind the Numberblocks television series, built around search-and-find scenes set in Numberland. Kids tap through busy backdrops looking for hidden Numberblocks characters, then add them together once they're found. It's less a game in the traditional sense and more an interactive workbook dressed up as play, and that distinction matters if you're deciding whether it earns a spot on your kid's tablet.

I've spent a fair amount of time with early-learning apps over the years, and most of them either lean too hard into flashy animation with no real learning underneath, or they're so worksheet-like that no toddler will sit through them twice. This one lands somewhere more useful. The hide-and-seek hook, borrowed straight from the show's most-loved episode, gives kids a reason to keep tapping around the screen, and the addition and number-bond practice rides along quietly in the background.

What Is Numberblocks: Hide and Seek About?

Numberblocks: Hide and Seek is a search-and-count app where players explore illustrated scenes across Numberland to locate hidden Numberblocks characters and their friends. Each scene rewards close looking rather than fast reflexes, which suits its audience of young children still building attention span.

Once a child spots a hidden block, the app has them combine it with others already found, turning the search into a simple addition problem. The design pulls directly from the show's first-series finale, in which Five proves so good at hide-and-seek that she can find everyone without looking up from her book. That episode is a fan favorite for a reason, and the app captures its cheerful, low-stakes tone well.

How Do You Play Numberblocks: Hide and Seek?

Play centers on tapping hidden shapes within a scene, then watching the found Numberblocks merge and recombine to demonstrate a sum. There's no fail state and no timer pressure, which is deliberate. Blue Zoo built this for four and five-year-olds who are just meeting numbers, not for kids who need a challenge curve.

What trips up new players, mostly parents handing the tablet over for the first time, is expecting more game structure than exists here. There's no scoring ladder, no unlockable worlds in the traditional app-game sense. The structure is straightforward:

• Explore a Numberland scene by scrolling and tapping
• Find Numberblocks characters and objects hidden in the artwork
• Combine found blocks to see addition and number bonds play out visually
• Move to a new scene once a set is complete

What Platforms Is Numberblocks: Hide and Seek Available On?

Numberblocks: Hide and Seek runs on both Android and iOS, available through Google Play and the Apple App Store respectively. Blue Zoo, credited as Publisher, lists the app at around 85MB, small enough that storage space is rarely an issue on a family tablet.

The listed version history shows updates through at least 1.2.1, released in September 2020, which tells you this isn't a title getting frequent content drops. It's a finished, stable product rather than a live-service app, and for a kids' counting tool that's honestly the right call. Parents don't want surprise redesigns confusing a routine their child has learned.

Who Is Numberblocks: Hide and Seek Best Suited For?

Numberblocks: Hide and Seek is aimed squarely at preschool and early primary-age kids, roughly three to six years old, who are just starting to grasp counting and simple addition. If your child already watches the show, the familiarity of Numberland and characters like One through Ten makes the app an easy sell.

It also works well as a calmer alternative to noisier tablet games. There's no reward-loop manipulation, no ads popping up mid-scene interrupting a four-year-old's focus. The best players I've seen with this kind of app are the ones who treat it as shared screen time, a parent sitting alongside pointing things out, rather than a device handed over solo.

Why Do Kids and Parents Like the Hide and Seek Format?

The hide-and-seek format works because searching is inherently satisfying for young kids, and pairing that instinct with counting removes the flashcard feel that turns so many of them off early math. Number bonds, the idea that 5 can be built from 2 and 3, or 4 and 1, click faster when a child physically discovers the pieces rather than being told the equation.

This mirrors what makes the source show effective in the first place. Numberblocks built a reputation among parents and early-years teachers for making number sense visual and tactile rather than abstract, and the app just moves that same philosophy onto a touchscreen.

Is Numberblocks: Hide and Seek Worth Downloading?

Numberblocks: Hide and Seek is worth downloading if you want a calm, focused counting app for a preschooler rather than a flashy arcade-style game. It won't hold the attention of an eight-year-old looking for competition or levels, but that was never the goal.

Rating-wise it sits in solidly average territory on the app stores, which tracks with how niche and function-first the app is. It does one job, teaching number bonds through a search game, and does it without clutter. If your household already has a Numberblocks fan, it's a natural next step from the show.
