su­doku – Create su­doku grids

The su­doku pack­age pro­vides an en­vi­ron­ment for type­set­ting su­doku grids.
A su­doku puz­zle is a 9x9 grid where some of the squares in the grid con­tain num­bers. The rules are sim­ple: ev­ery col­umn can only con­tain the dig­its 1 to 9, ev­ery row can only con­tain the dig­its 1 to 9 and ev­ery 3x3 box can only con­tain the dig­its 1 to 9.
More in­for­ma­tion, in­clud­ing help and ex­am­ple puz­zles, can be found at su­doku.org.uk. This site also has blank su­doku grids (or work­sheets), but you will not need to print them from there if you have this pack­age in­stalled.
