YJ MGC Square-1 – Picube + edge magnets — custom Square-1 with extra edge magnets and a professional Picube setup

YJ MGC Square-1 – Picube + edge magnets is a modified version of the popular YJ MGC Square-1, customized by Picube. Compared to the standard model, this edition adds extra magnets in the edges, greatly improving stability at high turning speeds. The base remains the same: a fully magnetic mechanism, smooth plastic-on-plastic feel and a comfortable, standard Square-1 form factor.

Picube pre-lubes and tunes the puzzle and also swaps the stock yellow caps for black caps that normally come in the box with the MGC. The result is a Square-1 that feels close to a professional setup right out of the box, with no need for disassembly and heavy DIY tuning.

Who is YJ MGC Square-1 – Picube + edge magnets for

Skill level:

• confident beginners who already know a basic Square-1 method;
• enthusiasts and advanced speedcubers who want a ready-to-go, competition-level main;
• competitors who care about stability, accuracy and fewer micro-adjustments at high TPS.

Best use:

• daily practice, long algorithm drilling and spam sessions;
• training for and competing at official WCA Square-1 events;
• improving averages and PBs thanks to a more predictable, stable turning feel.

What the Picube mod adds

• Extra edge magnets — on top of the standard MGC magnetic system, Picube installs magnets in the edges, a rare feature for Square-1 that brings a noticeable boost in stability during fast turning.
• More stable layers — edge magnets help layers snap more precisely into place and wander less, so you spend less time fixing layer alignment by hand.
• Professional lube and tension — the cube is lubricated with Picube’s own lubes and tensioned before shipping, giving a fast yet controllable feel out of the box.
• Black caps instead of yellow — the stock yellow caps are replaced with black ones from the original accessory set, giving a “stickerless black” style look and a color scheme many cubers find easier to recognize.
• MGC Square-1 core performance — you still get what made the original MGC popular: fully magnetic internals, plush turning and solid overall stability.

Setup and turning feel

• Soft, smooth turning — thanks to proper lubrication and plastic-on-plastic contact, moves feel very smooth with no harsh bumps.
• Excellent control at speed — the extra edge magnets reduce overshooting and unwanted extra clicks, which is crucial for fast, timed solves.
• Minimal need for extra tuning — the Picube version is designed to be used as a main straight away, with only minor adjustments needed if you want to customize it further.
• Comfortable standard size — the familiar Square-1 format fits both small and large hands well, with no learning curve in shape or proportions.

Who might not like it

• complete Square-1 beginners, who can start with a simpler, cheaper model first;
• cubers who enjoy “raw” cubes and prefer to do all the setup and lubrication themselves;
• anyone who wants an ultra-light, almost non-magnetic feel — this version deliberately has more magnets than the stock MGC.
