QiYi OS Cube 2x2-Blue — a “pop-tile” 2×2 shape mod for tactile solving and the satisfying goal of perfectly flat faces.

Manufacturer: QiYi MoFangGe. It’s a 2×2 with tiles that rise and sink as you turn; the goal is restoring the cube to fully flat faces (all tiles sunk). The blue version is stickerless; listed specs are about 67 × 67 × 67 mm and about 184 g.

Who it’s for

• Shape-mod fans and anyone who enjoys tactile, fidgety feedback.
• Collectors or a desk puzzle (the solved “flat” look is a great display trick).
• If you want a classic speed 2×2, this is more of a concept puzzle than a racer.

Turning / control feel

• Larger size gives a steadier grip than a standard 2×2.
• The tiles add extra feedback during turns, so it feels different from a normal cube.

Magnets & mechanism

• Built as a “magnetic OS” design (magnets are used in the pop-tile positioning/mechanism).
• The pop-tile system changes the surface shape while turning; solved state is fully flat.

Size, weight & materials

• Size: listed around 67 × 67 × 67 mm.
• Weight: listed around 184 g (much heavier than a typical 2×2).
• Color: blue, stickerless.

Main pros

• Unique pop-tile concept, not “just another” 2×2.
• Clear solve goal: flat faces.
• Tactile + visual, great for display.
• Big, satisfying in hand.

Possible nuances

• Size/weight make it less ideal for long speed sessions.
• Turning feel is intentionally different (tile feedback), which won’t be for everyone.

How to use

• Turn layers like a 2×2 and track the tile positions.
• Goal: all faces perfectly flat with no raised tiles.

Packaging & what’s included

• Listed package gross weight ~312 g; package size ~111 × 120 × 111 mm.
