Support for multiple letters per cell
In the puzzle environment simply enclose the letters in braces as in the following example: |[4] {xe} |[5] p |. Maybe some parameters have to be adjusted to fit the content into the cell. The cell can contain more complicated LaTeX constructs. Then additional braces might be required: |[4] {{\small xe}} |[5] p |.
