Games::Sudoku::General is a module to solve the class of puzzle that involves allocating symbols among sets such that no set contains more than one of any symbol. Sudoku is the most common name for such puzzles, though Number Place and Wasabi have also been used. Each puzzle is considered to be made up of a number of cells, each of which is a member of one or more sets, and each of which may contain exactly one symbol. The contents of a number of cells are gven, and the problem is to deduce the contents of the rest of the cells. This module is installable by the usual incantation: gunzip Games-Sudoku-General-9.999.tar.gz tar -xf Games-Sudoku-General-9.999.tar perl Makefile.PL make make test make install You can skip the gunzip step if your tar allows you to say tar -xzf Games-Sudoku-General-9.999.tar.gz Of course, since it's pure Perl, you can just expand the kit and drop General.pm in the Games/Sudoku directory in the appropriate place in your @INC directories. The executable (bin/sudokug) needs to be dropped somewhere in your path. OS-specific notes exist for (at least) MacOS (meaning, Mac OS 9 and lower), MSWin32, and VMS. See the relevant README files for details.
