The Basic Plot
- Solve Centers
- Reduce Edges
- Solve Reduced Cuboid
- Fix 2 Swapped Corners
1. Solve Centers
The first stage is to solve centers. Begin with the top and bottom faces (white and yellow in the videos below) and solve as you would a 4x4 center. Next, a maximum of 8 turns will render the remaining centers (red/orange and blue/green) solved.
2. Reduce Edges
Reducing edges consists of bringing together separate edge pieces, exactly as we would for reducing 4x4x4 edges. It's quick and there's no need to consider the orientation of the pieces, as the edges can only go in correctly in one way.
3. Solve Reduced Cuboid
We now solve the puzzle as a reduced 3x3x4. First, turn outer central layers to obtain a central solved strip. Next, place the reduced edges in position, using the edge piece series, so as to retain the central solved strip. If two edges need to swap, just turn the upper face one turn, then re-solve the edges.
Then, to solve the corners, use the corner piece series for cuboids (U R2 U' L2) x 2. It's simple, and will cycle the piece UBL->UDL->UDR.
4. Fix 2 Swapped Corners
It's possible to end up with everything solved except 2 corners which are swapped. To deal with this, simply turn the left of the puzzle 180°. Then re-reduce edges, and re-solve the puzzle.
And that's it. Your 4x4x3 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. To buy this puzzle, click here.
