I’ve been looking for something my son and I could do with our hands rather than another reason to look at a phone. An after-school cube activity got him interested, and he gradually learned to handle more puzzles. The Ex-Mars AI Robot Cube arrived in the middle of that interest. I expected little more than a motorized novelty at first. After two weeks in the living room, with the whole family trying it, the range of things it could do made it more interesting than that first impression.
Package and Components
The box contains the cube, charging cable, and manual. It has a built-in battery, although the Micro 5-pin USB charging connector feels dated. The lengthy manual hints at just how many functions are packed inside.
A Fresh Pixel Design
Unlike a conventional 3×3 cube, each face has a grid of tiny LEDs. Lit up at night, it looks good on a desk. The dimensions are familiar, but the motors and sensors add weight, giving it a more substantial feel in the hand.
Modes for Solving, Scrambling, and Practice
- 00 Mode: Free play, like a regular 3×3 cube. Choose this when you want to work through a puzzle yourself without guidance.
- 72 Mode: The internal motors solve the scrambled cube. Watching it put itself right is impressive, especially when you’re stuck. It’s quite something to see the familiar puzzle turn under its own power.
- 30 Mode: The motor creates a random scramble, saving you from mixing it manually and giving you a fresh puzzle for speed practice.
- 10–17 Modes: These are algorithm practice levels. LED cues show which way to turn next, giving children a path through a puzzle without requiring them to remember every move unaided. Kids who had given up while memorizing formulas could follow the illuminated instructions and finish for themselves. The process feels more like working through a game quest than staring at another written sequence.
App Connectivity and Extended Features
The app adds several ways to keep using the cube. You can compete against other owners and compare solving records, giving children a reason to improve their own times. Two-way synchronization also lets movement on the physical cube appear in the app, while changes made in the app are applied back to the cube. Either side can become the starting point for an interaction.
Alongside 3×3, Plus, Diamond, and X-puzzle settings provide other challenges to keep exploring.
Pros and Cons
Pros
- The Auto-Scramble function saves the work of mixing the cube by hand.
- Timers and app records encourage children to improve their solving speed.
- App connectivity adds new ways to play, rather like a coding robot.
Cons
- The motors make a noticeable mechanical noise in a quiet room.
- Turning feels slightly stiff, making advanced speed-cubing finger tricks difficult.
- Charging uses the older Micro 5-pin connector.
Final Verdict
Consider the child’s age and temperament before choosing it. For an elementary-school gift, it combines learning with enough fun to make the practice engaging. I’d install the app before handing it over so the full range of features is ready to use.
Digital Convenience Meets Analog Charm
Looking at it on the desk makes me think about how technology changes play. The same puzzle that once left us struggling with formulas written on paper can now offer guidance directly through the object in our hands. I don’t think keeping children away from every device is necessarily the best answer. This feels like a more constructive use of the technology. Sitting beside my son and concentrating together, I stop paying attention to the sound of smartphone notifications.
