Reihen und Spalten
fills in the blanks with possible numbers by looking at the existing numbers in each row and column. If only one value is possible its written to the board in a large blue colour.
Jedes Quadrat
does the same as the first test but it looks to eliminate possibles by checking all the existing numbers in each of the nine 3 by 3 boxes.
Paartest
We know we can eliminate numbers if two squares have two identical pairs of numbers. For example, if a row has 3-7 and 3-7 then all other 3s and 7s in that row can be eliminated. Same goes for the box and column.
Quadrat und Linienreduktion
This is part of the Box tests but I've seperated it so it can be seen. We check the box against the rows and columns that intersect it for each number. See here for more.
