How to approach it
The shift opens with a square and then a tee. The first long bar arrives as crate number 7. Over the first 21 crates the longest wait between two bars is 5 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 Normal the crates start at level 4.
- The bar is late here: build flat on the other nine columns and do not fill the open one while you wait.
- Keep the left and right edges level with the middle; a deep side well is hard to fill with anything but a bar.
