Skewb Topology Map

A Skewb is a 3×3 with the edges removed: 24 corner stickers plus 6 face centres = 30 stickers. Here they all sit at crossings of concentric circles, and each of the four corner turns is a 120° rotation of one half of the puzzle.

U120°U

L120°L

R120°R

B120°B

A Skewb turn rotates one half of the puzzle — 4 corners plus 3 centres, 15 stickers — by 120°. Press R below and watch which dots travel together: that group is exactly what one turn moves. Every face is a cluster of 4 corner dots around 1 centre dot.

How to Use the Skewb

Getting started takes seconds. No installs, no sign-up — just open and play.

Scramble the Skewb

Hit the Scramble button (or press S) to randomize the Skewb with 10–30 corner twists.

Twist the corners

Drag any colored sticker, or tap the U / L / R / B buttons. Each letter is one of the four corner axes; hold Shift for a counter-clockwise twist.

Solve it

Press Solve to replay your moves in reverse and return the Skewb to its solved state — the timer tracks every second.

Drag to look around

Click and drag the background to rotate the camera, scroll to zoom, and double-click to reset the view.

Features

Everything you need to practice and master the Skewb.

True 3D corner-twist

14 pieces — 8 corners + 6 face centers — driven by four body-diagonal 120° rotations, pure CSS 3D.

Always solvable

Every scramble is recorded, so the one-click solver can always undo it perfectly.

Power through solves with full keyboard control of every corner twist.

Frequently Asked Questions

Everything you might want to know about this online Skewb.

Is this Skewb simulator free?

Yes, completely free. It runs in your browser with no download and no account required.

How is the Skewb different from a Rubik's Cube?

Although the Skewb is cube-shaped, its turns rotate around body diagonals (through the corners), not around the faces. Each turn is a 120° rotation, so the Skewb has only 4 moves and feels very different from a 3×3.

Can the Skewb always be solved?

Yes. The solver replays your recorded scramble in reverse, so the Skewb is guaranteed to return to its solved state every time.

What do the letters U, L, R, B mean?

They name the four corner axes (Up-left, Left-back, Right-front, Back-right). Each letter twists that corner 120° clockwise; add an apostrophe (Shift) for counter-clockwise.

Does it work on mobile phones?

Absolutely. The interface is fully responsive: drag a sticker to twist, pinch to zoom, and tap the large move buttons.

Is the site available in my language?

The interface is available in 10 languages including English, Chinese, Spanish, Portuguese, Russian, French, German, Japanese, Korean and Vietnamese.

How a Skewb Turns — See the 120° Corner Rule on One Flat Map

A Skewb looks completely different from a cube, yet its structure is simpler: it is a 3×3 with the edges removed — 8 corners plus 6 face centres, 30 stickers in total. This map uses the same skeleton: three axes of three concentric circles, the 24 corner stickers on the inner and outer rings, and the 6 face centres on the middle rings, forming six clusters of “4 corners + 1 centre”.

30 stickers = 24 corners + 6 centres

Each face shows only 5 stickers (4 corners and 1 centre), so the map has six 5-dot clusters — one cluster per face, exactly like the 9-dot clusters of the 3×3.

See which 15 stickers a turn moves

A Skewb turn is a 120° rotation about a corner axis and moves one half of the puzzle: 4 corners (12 stickers) plus 3 centres = 15. Press a button and follow those 15 dots.

The middle ring is the face centres

In every group the middle circle carries only face centres, while the inner and outer circles carry only corners — you can tell corners from centres at a glance.

How to read this map

Learn the three groups of rings first

The top group is the vertical axis (U / D), the lower right is the front-back axis (F / B) and the lower left is the left-right axis (R / L). Each circle inside a group is exactly one layer of that axis.

Turn one layer

Drag any face on the 3D puzzle, or press one of the buttons under the map. Watch the colours travel around a circle — a turn is always “one whole ring shifts along itself”, and the 3D puzzle moves with it in real time.

Follow a single sticker

Pick one colour and follow it. Every turn is a cyclic shift of the dots on one circle, and understanding that is understanding the skeleton shared by every algorithm.

FAQ about the Skewb topology map

How is a Skewb related to a 3×3?

Directly: a Skewb is a 3×3 with the edges removed — 8 corners plus 6 face centres. That is why its map shares the same interlocking-circle skeleton as the 3×3 map.

Why do Skewb turns use 120° instead of 90°?

Because a Skewb turns around its corners, not around its faces. The axis runs through a corner, so one full turn is 360° and the three corners swap places every 120°.

Can a beginner start with the Skewb?

Yes. It has only 4 possible turns and 30 stickers — the smallest rule set of the four puzzles here. Once you see which 15 stickers a turn moves, the real puzzle feels much easier.
