How Do the Board Positions Affect the Score?
The legend along the left side of the board specifies how the premium board positions affect the score. There are two types of board positions that affect the individual symbol score. these are labeled 2S and 3S, respectively. There are two more types of board positions that affect the entire equation score. These are labeled 2E and 3E, respectively. The individual symbol score awards are computed before the entire equation awards. Also, if a player places tiles on two 2E or 3E board positions in one turn then the calculation is applied twice.
