X Cross is one of the best ways to make your CFOP start feel faster and smoother. Instead of solving only the cross first, you solve the cross and your first F2L pair together, which can help you enter F2L with less pausing. You do not need to force it on every scramble. Once you know what to look for, you can start spotting easy X Cross chances during inspection and use them to build cleaner, faster solves.
X Cross means solving the cross and one F2L pair together at the start of a CFOP solve. In a normal solve, you build the cross first, then look for your first corner edge pair. With X Cross, you plan that first pair during inspection and solve it while the cross is being made.
A simple way to understand it is cross plus one. You still solve the four cross edges, but you also finish one F2L pair before normal F2L begins.
| Start type | What you solve | When it makes sense |
|---|---|---|
| Normal cross | Four cross edges | When the first pair is hard to track |
| X Cross | Cross plus one F2L pair | When one pair fits naturally into the cross |
| XX Cross | Cross plus two F2L pairs | When the case is very clear and you can plan more |
X Cross is not a required step. It is useful only when it makes your start cleaner. If the opening becomes confusing, a simple normal cross is usually faster and safer.
Start by planning your normal cross. Then look for one corner edge pair that is already close, already paired, or easy to connect with your cross moves. Use this quick check during inspection:
If the answer is yes, the scramble may have a good X Cross chance. If the plan feels unclear, skip it. A useful X Cross should reduce your first F2L pause, not make the opening harder to control.
Once you find a possible X Cross chance, keep the plan simple. You are not trying to solve the whole first layer during inspection. You only need a clean cross route and one F2L pair that can be solved without making the opening harder. A good X Cross plan usually follows three steps:
Start with the four cross edges. If your cross plan is already long or hard to control, do not add an F2L pair yet. X Cross works best when the cross itself is simple. Before you choose the pair, ask yourself:
If the cross feels unclear, stay with a normal cross. A reliable opening is better than a forced X Cross.
After the cross route is clear, look for one corner edge pair. Pick the pair that is easiest to see, not the pair that looks most clever. The best pair is usually one that can be handled in one of these ways:
| Pair action | What it means |
|---|---|
| Keep it | The pair is already connected, and your cross moves do not break it |
| Connect it | A cross move brings the corner and edge together |
| Insert it | The pair can go into its slot while the last cross edges are solved |
Do not chase a pair across the cube. If tracking it takes all your attention, it is not a good X Cross choice.
Tip: If you are not sure whether your route is really an X Cross, check it before you drill it. You can use CubeSolver AI to scan your cube with the phone camera or enter the colors manually, then follow the move sequence step by step. Try your own plan first, compare it with the guided solution, and see whether the first pair was solved efficiently or only added extra moves.
The idea becomes easier when you see it in a short case. The example below is not meant to be a fixed algorithm you must memorize. Use it to understand the pattern: the cross is planned first, and the first pair is solved as part of that same start.
Scramble: R U R' F R' F' R2 U' R'
Solution: R U R' F R' F' R2
In this example, the opening moves solve the cross while also completing one F2L pair. The last moves from the scramble are only there to set up the case. During practice, focus on how the pair is handled together with the cross, instead of waiting until the cross is finished and then searching for the first F2L pair.
After you try an X Cross, compare it with a normal cross. Ask yourself whether the route actually helped your solve. A useful X Cross should:
If it saves a few moves but makes you pause longer, it is not a better solution. X Cross should make your start smoother, not just more advanced.
Learning X Cross is mostly about better inspection, not memorizing long opening sequences. Start with easy cases and train yourself to see when one F2L pair can work with the cross. A good practice session should help you make faster decisions, not make every scramble feel more complicated.
Before you use X Cross in timed solves, practice it in a slower setting. This helps you test the idea without rushing your turns or guessing during inspection. The routine below keeps the focus on simple cases, clear tracking, and real improvement.
This helps you learn the difference between a useful X Cross and a forced one. If the X Cross makes the opening harder to remember or slower to execute, use the normal cross instead.
Most X Cross mistakes happen when you try to make the opening look advanced instead of making it easier to solve. Watch out for these problems:
A good X Cross should give you a smoother start. If it adds stress, extra moves, or a bigger pause, it is not helping that solve.
Use X Cross only when it gives you a cleaner start. During practice, focus on simple cases, steady tracking, and smooth movement into the next F2L pair. If an opening takes too much effort to plan or makes you pause after the first pair, choose a normal cross instead. The best X Cross is not the most complex one, but the one that helps your solve feel easier, faster, and more controlled.
Yes, but only if your basic cross and F2L are already stable. X Cross depends on seeing how cross edges and F2L pieces move together, so it will feel frustrating if you still need a lot of time to find each F2L pair. A good time to start is when you can plan most of your cross during inspection and solve simple F2L cases without stopping for every move.
There is no target number. Some scrambles make X Cross easy, and some do not. In real solves, you should use it only when the first pair is clear enough to track during inspection. If you spend too much time searching for an X Cross idea, you may lose more time than you save. Think of it as an option, not a rule.
No. X Cross can reduce moves, but it can also make the opening longer if you force the pair into a bad route. A useful X Cross should either save moves, reduce the first F2L pause, or make the start easier to follow. If it only looks clever but causes a pause right after the pair, a normal cross is probably better.
Not at first. When you are learning, focus on finishing the cross and one pair cleanly. After that becomes comfortable, you can start watching where another pair moves during your X Cross solution. Planning too much too early often makes inspection messy. One clear pair is better than two half planned ideas.
Beginners can understand the idea, but they should not make it a main goal too early. If you are still learning CFOP, spend more time on cross efficiency, basic F2L, and smooth turning. Once those feel natural, simple X Cross cases become much easier to spot. Learning it too early can make you overthink the start of every solve.
Yes. X Cross can work with any cross color. However, if you are not color neutral, it is usually better to learn it on your main cross color first. That keeps the practice focused and easier to repeat. Color neutral solvers can look for better X Cross chances on different sides, but that also adds more inspection work.
In most cubing discussions, X Cross and extended cross mean the same idea: solving the cross plus one F2L pair. Some cubers may use different wording, but the goal is still the same. You finish the opening with the cross solved and one F2L pair already placed.
