Fill in the grid so that every row and column contains each letter once, and so that the squares highlighted by the Associator always match. - Drag the red and blue arrows to move the Associator - Hold space to activate the Associator (or turn on "auto assoc") - Mouse over a square and press a letter key to fill in that letter - Mouse over a square and press Z to clear it - Press 0 to enter a puzzle code How to use the Associator: The arrows can be moved freely, as long as the red arrows' column and the blue arrows' row are the same (indicated by the green lines). When the red arrows are over a letter, the blue indicator goes to that letter's row. Similarly, the blue arrows control the red indicator's column. When both of the indicators are active, the cells they point to must contain the same letter. You win when the grid is full and there are no conflicts.
