Rubik’s Cube 3×3 MG3 Magnetic (Monster Go) — budget magnetic cube with an “almost flagship” feel

MG3 Magnetic 3×3 is a magnetic cube from the Monster Go line, a sub-brand of GANCUBE. The cube measures 56×56×56 mm, weighs about 81 g, and is made from safe ABS plastic.
Inside, there are 48 magnets that provide smooth and stable turning, while GAN’s signature honeycomb structure and good factory lubrication make the cube’s feel soft and predictable.

Who is this cube for

Level:

• beginner and intermediate speedcubers;
• casual cubers who want their first proper magnetic speed cube;
• also suitable for more experienced solvers as a reliable training 3×3.

Monster Go as a product line is originally focused on learning and development, but according to user feedback the MG3 / MG 3×3 Magnetic feels very close to flagship models.

Age:

• school-age kids and adults; the standard 56 mm size is comfortable for most hands.

Main uses:

• moving from a regular “store-bought” cube to a real speed cube;
• speed practice and algorithm drilling;
• everyday solves “for fun”;
• an affordable yet high-quality magnetic 3×3 for your collection.

Turning feel

MG3 Magnetic offers light, fast and at the same time controlled turning:

• thanks to the 48 internal magnets, turns are smooth and snap clearly into place;
• the honeycomb internal surface helps distribute lube evenly and smooths out the turning, removing unnecessary “grittiness”.

The overall feel is rather soft, with medium-strength magnets: the cube is neither “blocky” nor floppy, and it’s pleasant to turn at both medium and high speeds.

For a beginner, this cube immediately gives the sensation of a “real speedcube”, and an experienced cuber won’t feel held back by it being a budget model.

Magnets and adjustment

Magnetisation: 48 built-in magnets placed in the pieces create a stable but not overly strong layer alignment and help the cube self-align after turns.

Adjustment system:

• Numerical IPG, which can be adjusted by hand without a screwdriver — tension changes in discrete clicks;
• classic springs and screws under the center caps — you can fine-tune further if needed.

The idea of Monster Go MG3 is to offer a magnetic cube ready to use straight out of the box, with clear and simple adjustment and without expensive flagship extras.

Stability and corner-cutting (3×3)

According to shop and player reviews, Monster Go 3×3 Magnetic (MG3) delivers an almost flagship level of performance:

• solid forward and reverse corner-cutting for its price range — the cube “forgives” small underturns and doesn’t demand perfect technique;
• medium magnetic strength adds stability and helps maintain control at high TPS.

It’s not a top flagship on the level of GAN 11/13/15, but within its price category MG3 Magnetic is considered one of the best options in terms of the balance between speed and stability.

Size, weight, materials

• Size: 56 × 56 × 56 mm — the standard size of most modern 3×3 speedcubes.
• Weight: about 81 g — slightly heavier than ultra-light flagships, but the cube feels solid and reliable in the hand.
• Material: eco-friendly ABS plastic, free from phthalates and lead, aimed at being safe for children.
• Colors and finish: bright stickerless plastic (no stickers) with rich shades and a smooth outer surface; honeycomb structure on the internal pieces.

Key advantages

• Budget magnetic cube with a feel close to more expensive GAN models.
• 48 magnets and a honeycomb interior — smooth, stable turning and even lube distribution.
• Suitable for any level: from a first serious 3×3 to a permanent “workhorse” cube for training.
• Safe materials designed with kids and beginners in mind.
• Simple and easy to maintain: the Numerical IPG lets you adjust tension without special tools.

Who it might not be ideal for / nuances

• For those looking for the most advanced flagship with a magnetic core, MagLev and fine magnet adjustment, the MG3 will feel relatively simple — it’s a solid mid-budget workhorse, not the top of the GAN line.
• If the buyer has never used a speedcube before, some people may feel more comfortable starting with a slightly calmer non-magnetic or educational model (Monster Go EDU, MG3 Standard, etc.), and only then moving on to the faster magnetic MG3.
