+.B sudoku
+.I Sudoku
+is a puzzle game from Japan.  The goal of the game is to
+fill the numbers 1 to 9 in all squares of the 9x9 board following a
+few simple rules: no digit should repeat on the same row and column,
+and no digit should repeat in the same 3x3 boxes outlined with thicker
+lines.  The board is initially filled with a partial solution which
+can be used for inferring digits for the empty squares.  The top row
+of the board contains the digits 1 through 9, clicking on one of those
+digits selects that number for placement on the board, clicking it
+again will deselect that digit.  Clicking on an empty square will then
+affix the square with the selected digit or, if no digit is selected
+empty the square.
