Step 2 of 7
First layer corners
Complete the white bottom face by placing its four corners, each lined up with the centres of its sides, without breaking the cross. For each corner, turn the whole cube so that its place is at the bottom front right, and apply the matching basic situation. A corner stuck at the bottom in another place first goes back up: bring that place to the front right, do R U R', then take the corner from the top.
The basic situations
Hold the cube as the hint says, then apply the formula. In the app, every formula is animated on a virtual cube.
On top, white on the right
The corner is on top: turn U until it is at the front right, above its place, white on the right face.
R U R'→ piece in placeOn top, white in front
The corner is on top: turn U until it is at the front right, above its place, white facing you.
F' U' F→ piece in placeOn top, white up
The corner is on top, white facing up: turn U until it is at the front right, above its place.
R U2 R' U' R U R'→ piece in placeAt the bottom, white in front
The corner is already at the bottom front right, but its white faces you.
R U R' U'→ On top, white upAt the bottom, white on the right
The corner is already at the bottom front right, but its white is on the right face.
R U R' U'→ On top, white on the right
