The Complete Guide to Cross Planning
Fifteen seconds. That's how long WCA competition rules give you to inspect the cube before a solve. Most cubers spend those fifteen seconds staring at the cube without a real plan. Advanced cubers spend them solving the entire cross in their head before their hands move. This guide is how you become the second kind.
Cross planning is the single highest return on investment in all of speedcubing. Learning full OLL takes 200+ hours to fully internalize. Color neutrality takes six months to develop properly. Fast turning requires years of muscle-memory work. Cross planning, by contrast, can shave two to three seconds off your average within four weeks of focused practice, because you're not learning anything new. You're just using time you already have.
The 15-Second Rule
Before every official 3x3 solve, competitors get up to 15 seconds of inspection time. During inspection you can pick up the cube, rotate it, and look at every face, but you cannot turn any layers. If you don't start the solve within 15 seconds you get a +2 penalty, and if you haven't started by 17 seconds the solve is a DNF (it doesn't count).
Most cubers learn this rule, use maybe five seconds of inspection to find a convenient-looking cross edge, and start turning. Those missing ten seconds are the difference between a 25-second average and a 20-second average. The math is simple: if your cross currently takes 4 seconds to execute during the solve, moving that planning into inspection drops it to 1–2 seconds of pure execution. Multiply by 50 solves a week and you've found hours of pure improvement with no new algorithms to learn.
What "Cross Planning" Actually Means
Cross planning is the mental rehearsal of every move required to solve the cross, performed entirely in inspection before the timer starts. When you start turning, you don't look at the cube, your hands already know the sequence. A planned cross is executed, not improvised.
This differs from what most intermediate cubers do, which is better described as cross scouting: looking at where the white edges currently are, getting a general idea of which face to start on, and making it up as you go. Scouting is better than random turning but it's not planning. A planned cross has a complete move sequence memorized before move one.
The Five-Stage Cross Planning Skill Tree
Cross planning isn't a single skill. It's a stack of five skills learned in order. Trying to jump directly to full cross planning is why so many cubers abandon the effort after a week. Each stage below typically takes one to three weeks to solidify, and the total journey to reliable full cross planning takes most cubers roughly two to three months.
See All Four White Edges
Before you can plan anything, you need to be able to locate all four white edges on a scrambled cube within about six seconds. This sounds trivial until you try to do it without turning the cube. Most beginners can only find two edges in six seconds because they haven't trained their eyes to scan systematically.
Drill: scramble the cube, start a timer, and point to each of the four white edges as you find them. Stop the timer. Repeat 50 times. Track your time. Goal: under six seconds to find all four consistently. This is pure pattern recognition and it tightens up within a week of daily practice.
Plan One Edge
Now add thinking. During inspection, locate the four white edges, pick one, and work out the shortest sequence of moves to bring it to its correct slot on the bottom. Two to four moves, ideally. After the 15 seconds are up, execute your planned moves and verify you placed the correct edge.
The trap: most cubers at this stage plan the move sequence and forget which edge they were planning for. That's not a failure, it's the exact thing the drill is training. Your brain is learning to hold a piece identity in working memory while also holding a move sequence. Two weeks of practice is usually enough to make this automatic.
Plan Two Edges
This is where the real difficulty begins. Planning edge one is easy. Planning edge two requires you to mentally simulate the cube state after edge one is placed, because the moves for edge one will have moved other pieces around. If your planned sequence for edge one was "F, D, R'", then during inspection you need to mentally track what the cube looks like after those three moves before you can plan edge two.
This is a genuinely hard cognitive skill, and two-edge planning typically takes three to four weeks to become reliable. Most cubers stall here briefly, feel like they've plateaued, and push through. The plateau is temporary, the neural pathway being built is real, just slow to form.
Plan Three Edges
Once two-edge planning works, three-edge planning is a notable jump but no longer qualitatively harder. You're mentally tracking three sequential cube states. At this level, most cubers start to notice they have a few seconds of inspection left over, use those seconds to double-check your plan, not to start planning the fourth edge yet. Rushing into four-edge planning before three-edge is rock-solid introduces errors that cost more time than they save.
Full Cross Planning
All four edges planned before your hands move. At this point your cross will typically take six to eight moves total and execute in about one to two seconds. You'll also start noticing where the first F2L pair is naturally landing, which opens the door to the elite stage: cross + 1, where you plan cross plus the first F2L pair in inspection. Cross + 1 is the skill that separates sub-12 cubers from sub-15 cubers, but it requires genuinely mastered full cross planning as a foundation. Don't shortcut here.
The Efficiency Problem
Planning a cross you can execute in six moves is a completely different skill from planning one that takes twelve moves. Efficient cross solutions rarely look like the solutions a beginner would find intuitively. They use non-obvious rotations, sometimes solve edges out of the order they appear, and often involve wide turns that handle multiple pieces at once.
Rough move-count benchmarks at each skill level:
- Beginner: 10–15 moves to solve cross
- Intermediate: 8–10 moves
- Advanced: 6–8 moves
- World-class: 5–7 moves, nearly always
Cross efficiency and cross planning are distinct skills, but they compound. An inefficient cross you've planned in inspection still beats an efficient cross you're making up move by move, but an efficient cross you've planned beats both by a wide margin. Work on them in parallel.
Four Drills That Actually Build This Skill
Blindfolded cross. Inspect as usual, then close your eyes and solve the cross without looking. Open your eyes to check. If you got it right, your plan was solid. If you got it wrong, you executed from memory but the memory was incomplete. Do 20 of these per day. It's the fastest way to develop honest cross planning rather than cross scouting.
Slow planned cross. Plan your full cross in 15 seconds of inspection, then execute at 2 turns per second. The slow execution forces your plan to actually be complete, at full speed you can get away with improvising on the last edge, but at 2 TPS you'll stall obviously if you haven't planned every move.
Extended inspection. Give yourself 30 seconds of inspection instead of 15, and use the extra time to plan cross plus as many F2L pairs as you can see. This is pure planning work with no execution pressure. Over weeks, the skill transfers and you start planning more in the standard 15 seconds without trying.
Single-edge sprints. If stage 2 is giving you trouble, scramble the cube, pick one specific white edge at random, and race yourself to find the shortest solution under 10 seconds of inspection. No execution, just planning. Do 30 of these in a session. The efficiency of your brain's search algorithm improves measurably with this drill.
Common Mistakes
Skipping efficiency work. Cubers who plan every solve but still use 12-move crosses are half-working the problem. A planned, efficient cross is 3–4 seconds faster than an unplanned, efficient one, and 5–6 seconds faster than a planned, inefficient one.
Forcing the same starting color every time. White-only cubers often find scrambles where white cross is awkward but yellow cross would be trivial. Even without full color neutrality, knowing how to solve a white-bottom OR yellow-bottom cross (dual color neutrality) doubles the number of scrambles where you get an easy start. This pairs perfectly with cross planning because you're already evaluating options during inspection.
Not practicing in timed conditions. Planning crosses in a relaxed casual setting trains different neural pathways than planning under the pressure of a running inspection timer. Use a timer during every drill session. The pressure is part of the skill.
Giving up during stage 3. The jump from one-edge to two-edge planning is the hardest single transition in cross planning. Many cubers hit this wall and conclude they're "not good at inspection." They're just not past the wall yet. Two weeks of focused daily practice breaks through it almost every time.
Honest Timeline
Why This Is Worth It
Cross planning is boring to practice. There's no satisfying click moment like learning a new algorithm; the improvements show up gradually, almost imperceptibly, across dozens of solves. This is probably why most cubers skip it, speedcubing culture tends to celebrate flashy algorithms over foundational skills, and cross planning is about as unflashy as it gets.
But if you talk to any sub-12 cuber and ask what the single most important habit change was on their way down from sub-20, cross planning is almost always in the top two answers. It's the skill that compounds. Every solve you do for the rest of your cubing life becomes faster because of the work you put in during these three months. Very few training investments in this hobby pay dividends that long.
Start drilling recognition while you build cross skills
Cross planning pairs perfectly with OLL, PLL, and F2L recognition training, practice both in parallel for the fastest overall progress.
