MoYu HuaMeng YS3M 3×3 20 Magnet Ball Core UV — top-tier YS3M with a ball core, 20 core magnets and a grippy UV finish

MoYu HuaMeng YS3M 3×3 20 Magnet Ball Core UV is one of the most advanced variants in the YS3M line: a spherical ball core, a 20 core-magnet system for maximum stabilisation, and a glossy UV-coated stickerless shell for strong grip and extra durability.

This cube is built for serious speedcubing: fast, very stable, with a clear magnetic track and a compact, “monolithic” mechanical feel. The UV finish helps you keep control even at very high TPS.

Who is this cube for

Skill level:

• advanced and competition cubers who want the most out of the YS3M series;
• confident intermediate cubers ready to move up to a serious competition flagship;
• enthusiasts who specifically want both a ball core and a premium UV finish.

Age:

• teens and adults who train regularly and compete;
• kids around 9–10 years old who already solve 3×3 confidently and treat cubes with care;
• as a first cube it may be overkill — it really feels like a performance tool.

Main use cases:

• daily intensive practice and drilling advanced algorithms;
• preparing for official competitions and using it as your main on stage;
• chasing personal, club and national records;
• a “top-spec” YS3M for cubers who want the best version right away.

Turning feel

• fast, light turning, while the cube still feels very “locked-in” and on rails;
• the ball core and 20 core magnets create a solid, stable mechanical feel with almost no wobble;
• magnetic click is medium to slightly strong, helping you hit 90° precisely and reduce overshooting;
• the UV finish adds a tacky grip — the cube almost sticks to your fingers, reducing slips;
• sound is soft, dense and fairly quiet — comfortable at home and in competition halls.

Overall, YS3M 20 Magnet Ball Core UV feels like a very confident flagship: it stays on track, handles high TPS easily and gives a lot of trust in your hands.

Ball core, 20 core magnets and magnetic system

Ball core + 20 core magnets:

• the spherical core is magnetically linked to the corners, improving layer centering after each move;
• 20 core magnets distribute stabilisation evenly throughout the cube;
• the cube wobbles less and feels geometrically solid even at maximum speed.

Edge and corner magnets:

• magnets in edges and corners create a smooth magnetic track and a pleasant click;
• magnetic strength is tuned between speed and control — neither too “concrete” nor too loose;
• most cubers will like the feel out of the box; fine-tuning is done via lube and tension.

UV finish, stability and corner-cutting

• the UV coating protects the shell from small scratches and adds extra grip;
• forward corner-cutting is at full modern flagship level, handling common misalignments with ease;
• reverse corner-cutting helps smooth out small catches during aggressive turning;
• the ball core reduces flex and “mushy” behaviour at very high TPS;
• the design lowers the risk of pops and accidental corner twists with sensible setup.

Size, weight, materials

• Size: standard flagship 3×3 (around 55 mm), comfortable for one- and two-handed solves;
• Weight: medium — substantial in-hand feel without tiring your hands too quickly;
• Shell: bright stickerless plastic with clear, high-contrast shades;
• Surface: glossy UV finish with a tacky grip, ideal for high-TPS solving.
