Product Description
The ShengShou Teraminx V3 Magnetic brings controlled, modern turning to one of the most complex mass-produced twisty puzzles available. With 732 interlocking modules arranged across a 7-layer dodecahedron, it offers a serious challenge, but its compact 41mm face size and 360 factory-installed magnets make that challenge far easier to handle.
Magnetic positioning guides each layer towards alignment, reducing disruptive slips and helping the puzzle stay composed through long, demanding solves. Combined with its smaller footprint, rounded geometry and adjustable mechanism, the V3 Magnetic feels more precise and manageable than its enormous piece count suggests.
Why you’ll like it
- 360 factory-installed magnets: Consistent positioning across the puzzle provides accurate feedback and helps reduce misalignments at speed.
- Compact 41mm faces: Shorter finger travel makes every turn easier to reach and control.
- 732-piece clip assembly: Hundreds of nested modules form a stable, complete dodecahedral structure.
- Widened outer pieces: Broader surfaces improve grip and make individual layers easier to identify.
- Rounded, fault-tolerant geometry: Shaped edges encourage layers to realign rather than catching during imperfect turns.
- Reinforced centre construction: A twelve-hole one-piece axis and clip-in centre caps keep the core region secure during fast solves.
- Balanced internal layout: Symmetrical components help manage weight and keep this large puzzle comfortable to hold.
- Bright stickerless colours: A clear twelve-colour scheme provides quick recognition with no stickers to peel.
Tuning and adjustment
Quick-access centre caps expose the adjustment points without requiring a major disassembly. The classic screw-and-spring system lets you tune axis distance and spring pressure for a looser, faster response or firmer control.
