Learn to solve the last layer cross on a 3x3 Rubik's Cube by practicing simple algorithms, observation skills, and step-by-step pattern recognition.



Step-by-step guide to solve the Last Layer Cross on a 3x3 Rubik's Cube
Step 1
Hold the cube so the two solved layers are on the bottom and the unsolved last-layer color is on top.
Step 2
Look at the top face and name the pattern you see: dot L-shape line or cross.
Step 3
If you already see a cross on the top face go to Step 10 to share your success.
Step 4
If you see an L-shape turn the whole cube until the L sits in the top-left corner of the top face.
Step 5
If you see a line turn the whole cube so the line is horizontal across the top face.
Step 6
Perform this algorithm once by turning faces in this order: front clockwise right clockwise up clockwise right counterclockwise up counterclockwise front counterclockwise.
Step 7
Look at the top face again and repeat Steps 4 to 6 until the top shows a full cross.
Step 8
When the cross appears stop turning and check that all four top edge stickers match the top color.
Step 9
Practice the detect-orient-and-run routine a few more times from a dot pattern to build speed and confidence.
Step 10
Take a photo or note of your finished last-layer cross and share your achievement on DIY.org.

Help!?
What can we use if we don't have a physical Rubik's Cube or can't take a photo?
Use a free cube‑solving app or a printable cube net to practice the hold-and-orient steps, and if you can't take a photo for Step 10, draw the finished cross or save a screenshot instead.
The algorithm doesn't seem to make progress—what am I doing wrong?
Check that the two solved layers are on the bottom and that the L is placed in the top-left or the line is horizontal before performing the algorithm F R U R' U' F' exactly once, then repeat Steps 4–6 until a full cross appears.
How can I adapt this activity for different ages?
For preschoolers, have an adult hold the cube and let the child name dot/L/line patterns, for early school ages practice performing the single algorithm slowly, and for older kids time repeated 'detect-orient-and-run' routines to build speed.
How can we extend or personalize the activity after making the cross?
Extend it by timing multiple attempts from a dot to a cross, keeping a progress chart, decorating the cube stickers for personalization, and sharing the finished cross photo on DIY.org as suggested in Step 10.

Facts about Rubik's Cube solving
⏱️ Top speedcubers often plan and place their cross during the 15-second inspection to save time in fast solves.
🎓 Ernő Rubik invented the cube in 1974 to teach 3D geometry; learning the last-layer cross builds pattern recognition and algorithm skills.
🎯 The last layer cross orients the four top edges and is the first step of the OLL stage in the CFOP method.
🔢 The Rubik's Cube has about 43 quintillion (43,252,003,274,489,856,000) possible positions—algorithms help you find the path!
🧠 There are just a few common last-layer edge-orientation patterns to learn: dot, 'L' shape, line, and the full cross.
