SquareWord puzzle is played on a square which is divided into cells with words written in them. The size of the play area varies from 5x5 up to 7x7 cells depending on the level. Most of the cells are empty to begin with. The task is to fill the empty cells with the available letters, so that in each vertical and horizontal row, and on the two big diagonals of the square, the letters are different.
The problem is solved by analyzing what letters it is possible to put into the chosen cell. Then on every game turn there will be a cell, which it is possible to put only one letter into. To take you turn, drag the letter with your mouse into the cell. To remove the letter, just click it.
