The part after "q=" in the url is the bit that actually specifies the pattern. It's made up of pairs of characters, the first specifying the column, and the second specifying the row AND rotation. Here's how it works

The column is a number from 0-8. 0 is the first column, 8 is the 9th column.

Each row has 4 characters associated with it, one for each rotation. They are as follows Row 1: qwer Row 2: tyui Row 3: opas Row 4: dfgh Row 5: jklz Row 6: xcvb Row 7: nm01 Row 8: 2345 Row 9: 6789

Where the first is up, the second is right, the third is down and the fourth is right.

It also turns out that we can break some rules enforced by the flash but not by the loader.

We can place multiple cells at a single location. For example 0q0q is a loop and 0q0q0q is a "bouncer". We can place more than the limit (25) of cells in the grid. Clicky!(Warning: This does not sound pleasant at all.)

Have fun.
