Stage 4 — the yellow cross

Look at the yellow stickers on the top face. You will see one of three patterns: a single dot, a line of three, or an L shape (sometimes called a hook).

Hold the cube so a line runs left to right, or so an L points to the back-left, then run F R U R' U' F'.

From a dot you will get an L or a line, from a line or an L you will get the cross. Repeat the sequence until the cross appears — never more than three times.
