How to approach it
The shift opens with a step right and then a square. The first long bar arrives as crate number 4. Over the first 21 crates the longest wait between two bars is 8 crates. A square comes within the first three crates, an easy piece for the first corner. It is a Marathon shift: no finish line, faster every ten rows. On Easy the crates start at level 1, slow enough to plan every move.
- Keep the left and right edges level with the middle; a deep side well is hard to fill with anything but a bar.
- Keep a long bar in Hold while the stack is low; it turns the open column into four rows whenever you are ready.
