Twist Cube 2x2

This puzzle simulation lets students handle a 2x2 cube with eight corner pieces. Dragging across a face turns that layer by a quarter turn, and dragging empty space rotates the view. Scramble mixes the cube, Undo takes back a move, and a slider sets the snap speed. Readouts track moves, state, best result and time. Teachers can use it for spatial reasoning, sequencing and algorithm thinking: ask students to find a short sequence that moves one piece, then compare strategies and move counts across the class.

• Press Scramble, then drag across a face to turn a layer and watch the Moves readout rise.
• Drag empty space to rotate the cube so you can see every side before planning a turn.
• Use Undo move to test an idea, and see whether the cube returns to its earlier state.
• Try to beat the Best readout by solving the scrambled cube in fewer moves.
• Change Snap speed to slow turns down and follow where each corner piece goes.

1. 1Visualize how a quarter turn moves corner pieces in 3D.
2. 2Plan a sequence of moves to reach a goal state.
3. 3Recognize that the order of turns changes the result.
4. 4Compare strategies using move count and time as evidence.
