The puzzle

Black out some of the grid cells. The numbers on the left and the bottom edge of the grid indicate the values of the cells for adding up. The numbers on the right and the top edge of the grid specify the sums of the values of the colored cells. Here’s a little self-explanatory example:

Commands

In the grid and around

valueH

valueH{csv list}

The command typesets the numbers left to the grid indicating the values of the cells. It expects a comma-separated list as an argument.

valueV

valueV{csv list}

The command typesets the numbers below the grid specifying the values of the cells. It also expects a comma separated list.

sumH

sumH{csv list}

The command typesets the numbers right to the grid indicating the sums of the values of the colored cells. It expects a comma-separated list.

sumV

sumV{csv list}

The command typesets the numbers above the grid specifying the sums of the values of the colored cells. It expects a comma separated list.

fillcell

fillcell{column}{row}

The command fills the grid cell {column}{row} with the color specified with the option color.

fillrow

fillrow{row}{csv list}

The command fills the grid row {row}. In {csv list} 1 means ’fill’ and 0 means ’don’t fill’.

fillcolumn

fillcolumn{column}{csv list}

The command fills a grid column.

Presentation

definecounterstyle

The command allows you to define your own styles. For example, the style left is defined as follows:

To typeset the counter into the margin we use the command marginnote. We need to use the command reversemarginpar to set the counter into the left margin. Of course, we must use this command in a group for local scope. Finally we use puzzlecounter in a tikz node with a vertical offset set with the option cvoffset.

puzzlecounter

puzzlecounter

The command provides the counter in textual form to use it for example in definecounterstyle.

titleformat

titleformat{format}

With the command titleformat, you can define the format of the title. By default, the definition is as follows:

titleformat{centeringLargecolor{blue}}

Miscellaneous

bokkususetup

bokkususetup{options}

With the command you can reset the options with global scope.

setpuzzlecounter

setpuzzlecounter{number}

With the command , you can reset the puzzle counter, for example before the solutions.
