RoFL (more recently known as CBL) is a speedsolving method for 2x2x2. The first step separates the upper and lower layer corners into their respective layers, regardless of orientation or permutation. Then an algorithm is used to solve both layers. It is similar to performing CLL or TCLL on both layers at once. TCLL is a method that was derived from RoFL.[1] RoFL has 2794 algorithms.
Naming Dispute
RoFL stands for Rotten First Layer, but in recent years people have been calling it CBL, probably due to the given names by North Americans Speedcubers.
- CBL stands for Corners of Both Layers according to Wiki Forums.
Steps
- All of the bottom layer corners are moved to the bottom layer without regard to their orientation or permutation. This automatically moves all upper layer corners to the upper layer. The 2x2x2 is now in a state similar to CLL or TCLL on both the upper and bottom layer.
- A single algorithm is used to solve both the upper and bottom layers.
Techniques
- Because both layers are in a CLL or TCLL state, it is possible to flip the 2x2x2 to have the bottom layer now be the upper layer. This is beneficial if the RoFL algorithm for one side is better than the other.
- It isn't necessary to learn all algorithm sets. Combined with the technique above and the fact that each scramble will have various possible solutions for the first step, users can set up to specific sets.
