The ShengShou Teraminx V3 7x7 Megaminx is a 7-layer dodecahedron built from 732 individual modules, tuned for high-order speedsolving in a smaller, more manageable 41mm size. This is the non-magnetic base build, giving you a lighter puzzle out of the box and the freedom to set up your own magnet configuration later.

Why you'll like it

• Compact 41mm size: A smaller footprint than typical 7x7 Megaminx puzzles, shortening the distance your fingers travel and making a high-order puzzle easier to control.
• Lightest build in the family: At 364g with no factory magnets, it's easy on the hands during long solves and keeps things simple if you want to build your own feel.
• Serious high-order challenge: Seven layers of dodecahedron give experienced solvers plenty to work through, with a stable structure that holds up to fast turning.

Tuning & control

• Screw-adjustable axis distance: Set tension and elasticity to your preference with the adjustment screws — no hard disassembly required.
• Quick-open center caps: Clip-on center covers make getting inside for adjustment fast and repeatable.
• DIY-friendly base: Non-magnetic out of the box, so you can dial in your own magnet setup if you want to customize the feel down the road.

Performance & design highlights

• 732-piece modular build: Assembled from 732 independent modules that interlock and nest together for a complete, stable puzzle.
• Twelve-hole one-piece core: A single integrated core keeps the structure locked down and resistant to popping during high-speed turns.
• Clip-fit center covers: Center covers seat into the fixed center pieces and grip the side and corner center blocks, locking the center region so it won't fall apart under speed.
• Symmetric internal design: Many internal components use a symmetric layout to reduce weight and improve grip comfort.
• Fault-tolerant rounded corners and widened shell: Rounded piece edges and a widened outer shell help the puzzle recover from slightly off-line turns.
• Classic stickerless finish: Bright, durable stickerless coloring with a smooth ABS surface built to hold up to wear.
