Square-1 Cube Shape Trainer

Learn cube shape intuitively by pairing edges.

4 edge pairs
Don't solve the top, then the bottom. Always look at both layers. A slice swaps pieces between them.
What you're looking for

Find singles. Protect pairs.

TOP
BOTTOM
Corner Single edge Edge pair
The method

Repeat this

1
Look at both layers

Find the white single edges.

2
Protect green pairs

Don't make a slice that breaks a pair you've already created.

3
Pick one single from each layer

Turn the layers so they can meet across the slice.

4
Slice /

Check the puzzle again and repeat.

Your goal isn't to solve a layer. Your goal is to turn: E + E → EE until you have four edge pairs.
Think about progress like this
E Singles
→
EE 1 pair
→
EE EE 2 pairs
→
EE EE EE EE 4 pairs
→
EEEEEEEE Gathered
(1,0) Turn top 30°
(0,1) Turn bottom 30°
/ Slice right half 180°
Never force a slice. The red line must run between pieces on both sides.
