What to do?

The total rule is considered to be fulfilled if the sum of all selected fields in a row or column matches the specified row or column total. In this case, the sum will be displayed in blue.

The goal is to fulfill the sum rule for all columns and rows.

If the sum of the selected fields is greater than the row or column total, the sum is marked in red.

Not always a sum is unique, so there may be different summands in a row or column that adds up to the same sum.

The level of game can be changed in the settings.
