Question
While playing Cogs, I have found myself plenty of times in this irritating situation. I have this:
.--.
|XY| (where I don't really care about X, Y, or Z)
|AB|
|Z |
....
...while what I want is this:
.--.
|AB| (where again, I'll sort X, Y and Z later.)
|XY|
|Z |
....
I'm tired of trying to get this by accident. By goodness, you how do you make that happen consistently?
Answer
.--. .--. .--. .--. .--. .--. .--. .--. .--. .--.
|XY| → |XY| → |XY| → |↓Y| → |Y←| → |YA| → |YA| → |↓A| → |A←| → |AB|
|AB| → |A↓| → |→A| → |XA| → |XA| → |XB| → |XB| → |YB| → |YB| → |Y↑|
|Z | → |ZB| → |ZB| → |ZB| → |ZB| → |Z↑| → |→Z| → |XZ| → |XZ| → |XZ|
