### Crazy 3x3x2

The Crazy 3x3x2 is a twisty puzzle in cuboid shape. One of the two 3x3x3 faces will have its center pieces turn when the face is turned, but the other won't.

This puzzle is interesting because which face that is depends on a corner, not on a center piece. The puzzle has a "lock piece" on one of its corners, so whichever face that corner is on will have its center pieces rotate with the face. On my puzzle and in these videos, the lock piece is the red/blue/white corner.

[There's also a secret move with this puzzle which makes things a little more bizarre. I won't be covering that...]

The Basic Plot
1. Solve inside the circle.
2. Solve the edges.
3. Solve the corners.

Step 1: Solve Inside the Circle

This can be done much like solving a 3x3x1 floppy cube. It's basically a matter of "fiddling" until it's solved. It's reasonably straightforward, as this video will show.

Step 2: Solve Edges

Next we solve the edges using edge piece series with setup moves. To start with, solve the four edges around the lock piece.

Once they're done, solve the rest of the edges in the same way.

Step 3: Solve Corners

Now that the edges are solved, we can solve the corners using a corner piece series. However, using a single corner piece series will also move around pieces inside the circle. We want to avoid this. So, we'll do as follows:
1. Hold lock piece at DBL or DBR or DFL.
2. Corner piece series first turn upper face clockwise.
3. Corner piece series first turn upper face anticlockwise
This is a pure 3-cycle of the outer corners. It cycles the corners UBL -> UBR -> DFR. To see this, have a look at this video.

Now let's see it in action on an unsolved puzzle.

And a final video showing the endgame.

And that's it. Your Crazy 3x3x2 is now solved. I trust this site has been helpful. If you have any questions or want some clarifications, please use the comments to do so.

1. I have 2 unsolved corners and can't use the corner swap algorithm. Help!

2. @tonydtocce

If everything else is solved and you have only two corners to swap, then it means the secret move has been done. I mention this near the start. This move is to hold the puzzle with a 3x3 face on top, then turn the middle slice up 90 degrees, and then turn the up face 180 degrees. I found that whenever this move had been done, I always finished with two corners to swap. The only way was to undo that move, and then start again.

3. Hi,

After doing the 2x2 3x3 4x4 5x5 6x6.
I want to try one of the crazy cube, where should i start ? i saw there 8 3x3 crazy cube, witch one is the best to start with ?

1. I think the crazy jupiter 3x3x3. if you get it, have a look at my reduction method for it, rather than the circle corners last method

4. What about Bermuda Cubes ? can you recommend ?

Thanks !

1. I'm really sorry but I don't have any bermuda cubes, so I can't help you there...
