Cube

Learn to solve a 3x3 cube: the notation, then the layer-by-layer method one step at a time, with a hint after every move. Solve today's scramble, a new one, or paint the cube in your hand and learn to solve it.

How to play Cube

Cube teaches the 3x3 cube. It starts with the notation, then walks you through a full solve one step at a time, and after every move it says whether the move helps, and what to turn next.

How it teaches

  • Notation comes first: seven short lessons (faces and letters, the prime, twice, all six faces, reading a sequence, turning the whole cube, slices and wide turns).
  • Then you solve a scrambled cube with a method of your choice. The coach judges every turn you make and, when you go off the plan, walks you back.
  • The Hint button explains the next move in plain words, and Show me turns it for you. In settings, hints can come after every move or only when you ask.
  • Today's scramble is the same for everyone and turns over at your midnight. New scramble gives another, and Paint my cube lets you copy the colours of a cube in your hand and learn its solve.
Cube's first Layers step, White cross: a papercraft 3x3 cube on a green cutting mat with its flat net below it, a hint card taped above the face-turn keys, and the Learn button in the bar at the foot.

The three methods

MethodStepsAverage moves
Layers7: white cross, white corners, middle layer, yellow cross, yellow edges, yellow corners in place, yellow corners turned154
CFOP6: cross, corner-edge pairs, yellow cross, yellow face, top corners, top edges71
Roux7: first block, second block, top corners up, top corners in place, edges up or down, left and right edges, last four edges58

The averages are over 300 fixed scrambles. CFOP and Roux each have a one-look setting for the top layer: CFOP drops to 56 moves and Roux to 48.

Home

Home shows today's scramble written in notation, with buttons for it, for a new scramble and for Paint my cube. Under Methods are the seven notation lessons, each marked when done, and a card for each method with a star for every one of its steps you have finished.

Controls

  • Tap a key to turn a face; the key with the move the coach wants is lit. A key with a prime turns the other way. Drag the cube to look at it from another side.
  • Keyboard: the face letters turn the faces, with Shift for the prime.
  • Flat view shows the cube as a net, and a tap on a face turns the cube to it.
  • The gear opens the skins (Craft card, Toy, Picture book and Symbols) and the turn speed.

Coins and saving

Each step finished pays 5 coins, once for each step of each solve. Your lessons, finished steps and skin are kept on your device.
