## 4x4x6 Algorithms

This was my *favorite puzzle* and when it fell and got destroyed in Sweden, I was heartbroken. However, a few years later, whilst living in Italy, I replaced it and – to my dismay – realized I had forgotten some crucial steps into solving it!

Things are really quite simple and matching those inner-edge pieces remains my toughest challenge. I figure I should catalogue this stuff for future reference, rather than relying on old YouTube videos to help me through. OK, let’s see!

- Solve centers (like a 4×4)
- Solve edges (like a 4×4)
- Return to Cuboid (like a 3×3)
- Make sure your two middle layers are good.
- Solve inner-edge pieces (I struggle here)
- Position inner-lower layer ‘cross’ segment
- Then solve inner-lower layer edges (like a 3x3x2): R2 / U / R2 / U’ / R2
- Now inner-upper layer edges (headlights)
- Headlights on Left (or 2x): R2 / U / R2 / U2 / R2 — u’ / d — R2 / U’ / R2 / U / R2
- Inner-edge swap (Opposite): R2 / U2 / R2 / U2 / R2
- Inner-edge swap (Adjacent): R2 / U / R2 / U — R2 / U2 / R2 / U2 — R2 / U / R2 / U’ / R2

- Middle-Layer Parity (If necessary): U2 / R2 / F2 / U2 / F2 / R2 / U2 / F2
- Now bottom centers (Intuitive)
- Bottom edges (just like step #7)
- Repeat Headlights & inner edges steps (#8)
- Middle-Layer Parity Redux (if necessary)

See if that makes sense the next time I need it!!!
