\maketitle

    A Sudoku puzzle consists of a 9 by 9 array of squares, some of which have
numbers in them, the numbers ranging from 1 through 9. The problem is to
fill in all the squares such that each row, column, and 3 by 3 box includes
the numbers 1 through 9 with no repetitions.

    This is a collection of some 54 Sudoku puzzles which I have culled
from various places. The sources include, among others:
the \emph{Sudoku Solver}~\cite{SSBL} website (labelled SE, SM, SH and SVH),
\emph{The Daily Telegraph}~\cite{DT2} (labelled TG, TM, and TT),
\emph{The Seattle Times} (labelled ST),
and some automatically generated by the \Lpack{createsudoku}
package~\cite{SUDOKUBUNDLE} (labelled CS).

You can try solving them yourself and/or get
LaTeX to do it for
you. The \Lpack{solvesudoku} package~\cite{SUDOKUBUNDLE} is able to solve
most, but not all of the puzzles. Other LaTeX packages may do better or worse.

    The puzzles are presented in approximately increasing order of difficulty.
Each source, though, has its own set of categories which don't necessarily
agree with each other (and sometimes not within one source). I have included
an indication of the difficulty as stated by the relevant source.

The parameters for the puzzles created via \Lpack{createsudoku} are given in
the table.
