Ex-Mars AI Robot Cube Review: Solve Rubik’s Cubes Under 1 Min

In an era where children are glued to digital screens, finding ways to keep them engaged with tactile, hands-on activities is a challenge. As a parent, I’ve been looking for ways to pull my son away from his smartphone. After enrolling him in a local cube club, his interest in puzzles grew, eventually leading us to the Ex-Mars AI Robot Cube. At first, I thought it was just a fancy motorized toy, but after having it in our living room for two weeks, I discovered it offers much more than just simple fun.

Package and Components

The box contains the unit, a charging cable, and a manual. It features a built-in battery, though it unfortunately uses the outdated Micro 5-pin USB connector. The manual is quite extensive, which reflects the vast range of features this device actually packs.

A Fresh Pixel Design

The exterior stands out from standard 3×3 cubes. Each face is made of a grid of tiny LEDs that light up beautifully when turned on. At night, it serves as a sleek desk accessory. While the size is similar to standard cubes, the internal motors and sensors give it a slightly heavier, more stable feel during use.

Incredible Modes Beyond Imagination

• 00 Mode: The basic state for free-form play, just like a standard 3×3 cube. It’s the most intuitive mode for when you want to solve puzzles on your own without any guidance.
• 72 Mode: If you’ve scrambled the cube beyond recognition, the device uses its internal motors to solve itself in seconds. It’s mind-blowing to watch it fix itself when you’re stuck.
• 30 Mode: The motor scrambles the cube randomly, saving you the effort of doing it by hand. It’s perfect for practicing speed cubing by providing a fresh puzzle every time.
• 10–17 Modes: These are algorithmic practice levels. Even children who previously gave up on memorizing formulas can complete the puzzles because the AI uses LED lights to indicate the next move, making it feel like clearing a video game quest.

App Connectivity and Extended Features

By installing the app, you can compete with others or track your records. The app also features a two-way synchronization mode, where actions on the cube reflect in the app and vice versa.

Beyond the standard 3×3, the settings support Plus, Diamond, and X-puzzle modes, ensuring you won’t get bored anytime soon.

Pros and Cons

Pros

• The Auto-Scramble feature eliminates the hassle of manually mixing the cube.
• Built-in timers and app integration motivate children to improve their speed.
• Like a coding robot, the app connectivity opens up endless gameplay options.

Cons

• The internal motor makes a noticeable mechanical sound, which can be loud in a quiet room.
• The rotation feels slightly stiff, making advanced “finger tricks” used by speed cubers difficult to perform.
• The charging port uses the obsolete Micro 5-pin standard.

Final Verdict

It is worth considering the child’s age and personality. If you are looking for a gift for an elementary school student, this is a meaningful choice that balances educational value with pure fun. I highly recommend installing the app beforehand to unlock all features.

Digital Convenience Meets Analog Charm

Seeing this device on my desk makes me realize how technology has transformed the way we play. In the past, people struggled for days with paper formulas; now, this smart device offers friendly guidance. Instead of blindly banning technology, utilizing it in productive ways like this is much wiser. It’s a great way to spend time focusing with my child—a moment where the sound of smartphone notifications completely fades away.
