The Cross Phase
CFOP's first phase: solve four White cross edges aligned to matching side centers. Optimal in 8 moves or fewer; daisy beginner shortcut. Progression from edge-by-edge to full-inspection planning to color-neutrality. X-cross advanced trick. Why cross quality determines the rest of the solve.

The Cross is the first phase of CFOP. Its goal is to solve the four edges of one face (traditionally the White face) so that each cross edge not only sits next to the White center but also aligns with its correct side center on the adjacent face. A cross where White edges are in place but the side colors do not match the side centers is not a finished cross; it is a common beginner mistake that makes the rest of the solve unrecoverable without rework. A gentler beginner approach is the daisy method: place the four White edges on the Yellow (top) face forming a daisy, then flip each one down into the matching side center. This keeps colors aligned by construction at the cost of a few extra moves.
An optimal cross is always 8 moves or fewer on any scramble. Serious CFOP solvers aim for a cross-in-8 or even cross-in-6 average. What separates intermediate from advanced Cross execution is planning rather than speed. WCA regulations grant 15 seconds of inspection before the timer starts, during which the solver may look at the cube but not turn it. Advanced solvers use this window to plan the entire cross, and top solvers often plan the first F2L pair as well (an X-cross, where the cross and one F2L pair are solved simultaneously).
The learning progression for the Cross has three visible steps. Beginners solve one cross edge at a time, re-gripping and re-orienting the cube between each. Intermediates plan all four edges during inspection and solve the cross without any cube rotations. Advanced solvers adopt color neutrality: instead of always starting the cross on White, they pick whichever of the six faces has the cheapest cross on that particular scramble. Full color-neutral (CN) cubers report roughly 1.5 fewer moves per cross on average and gain about 1-2 seconds on their overall time. Dual CN (White plus Yellow) is a common stepping stone for solvers who find full CN too memory-heavy.
