Product Description
The ShengShou Master Kilominx V3M takes the 4x4 megaminx that solvers already trusted and adds a built-in magnetic system — so every layer snaps into position with a satisfying click, and your turning stays controlled even when you push the pace.
Same 4x4 megaminx challenge. Same precision assembly. Now with magnets doing the alignment work for you, so you can focus on the solve rather than correcting overshoot.
Magnetic system
- Built-in magnets: Integrated throughout the puzzle to guide layers into alignment on every turn — reduces overshoot and keeps your solving rhythm consistent.
- Controlled feel: The magnetic snap adds a tactile reference point that makes fast, confident turning more forgiving.
Built for stability at speed
- Twelve-face megaminx structure: Precision-engineered internals keep the puzzle locked and resistant to popping mid-solve.
- Fault-tolerant rounded corners & widened shell: Built-in forgiveness helps layers realign instead of catching.
- Hollowed internals: Weight-reduced components keep the puzzle comfortable through extended solves.
Tuning & control
- Screw-adjustable tension: Dial in feel by hand — looser for speed, tighter for control.
- Adjustable elasticity: Set the spring feel to match your turning style.
Specs
- Puzzle type: 4x4 Megaminx (Master Kilominx)

The magnetic upgrade for cubers who know the Master Kilominx and want magnetically assisted control at speed.
