If nothing happens when you press the key, click on the applet background to get its attention, then try the key again.
Provided of course you know the 99 turns. But why?
We know that this 99-turn has a magic-number which we do not know beforehand. But if we repeat this 99-turn repeatedly, we will reach this magic-number (and a restored Rubik's Cube).
In Group Theory (a university Math course), this magic-number is called the order for this 99-turn. This 99-turn and all its repeats together form a cyclic group of order=magic-number. Interestingly, the 198-turn (consisting of two 99-turns) has a different order which is a divisor of the 99-turn order.
This theory is useful because it re-assures us that the repeat-until-done trick is possible.
But honestly, if you know the 99-turn, you could just do the reversed turns in reversed order.
You can enter a move in DBLFUR notation:
- Each turn is [DBLFUR]['-i"2]
- Example 1: FUB2U-F' (5 turns)
- Example 2: D,L,R",D',L' (5 turns)
- [DBLFUR]::Down,Back,Left,Front,Up,Right face.
- By itself, each means clockwise 90° turn.
- ' or - or i means anticlockwise 90° turn.
- " or 2 means 180° turn.
or BFR (GANPuzzle) notation:

Every cube state in the step by step dialog has a link that leads you to a wiki webpage that provide details on that state, including discussions and questions from other users.
You can also contribute your insights or ask or discuss a point pertaining to this state.
There shall be no shortage of detail or discussion on every cube state, thanks to the power of wiki.
Internet connection is required to access this VirtualCubeWiki which is the collection of all these wiki pages, one for each cube state.
You can slow the animation speed to observe the moves or you can speed it up.
You can even change the speed in the middle of a animation.
You can save/restore a rubik's cube state to/from a file in your computer or memory in the sandBox panel (in [Option]-tab). Here is a valuable learning tip:
1. Scramble a cube then save it to file.
2. Restore the saved scrambled cube from file.
3. Study the step-by-step solution.
4. Repeat step 2 as often as you wish.
This allows you to be familiar with the same moves over and over again.
Key-1 to Key-5 are for Trick1 to Trick5.
You can assign key-6,key-7 and key-8 to execute your favourite moves:
1. Click [Option]-tab in the cube applet.
By editing a simple text-file in your computer, you can change your start up options such as:
1. playAudio = true, playAudioIntro = false
Look for a text file in your installed folder with extension ".cfg".
Other benefits such as
† No need for internet connection.
You can record your favourite move and assign it to key-6, key-7 or key-8.
Play back your move by pressing key-6, key-7 or key-8.
This is a great feature when you use a move over and over again to solve the puzzle.
Please rate this Demo software from
1 (very bad) to 10 (very good).
