Draw lines to divide the letters into regions. Lines can be horizontal, vertical, or 45 degree diagonal, but must be gridpoint-aligned and travel all the way across the board. Every line must border at least one lettered region. R must be rectangular (not square), S must be square, and T must be in a right triangle.
