EACH number in our Codeword grid represents a different letter of the alphabet. For example, today 18 represents S, so fill in S every time the figure 18 appears. You have two letters in the control grid to start you off. Enter them in the appropriate squares in the main grid, then use your knowledge of words to work out which letters should go in the missing squares. As you get the letters, fill in other squares with the same number in the main grid and control grid. Check off the list of alphabetical letters as you identify them. Solution in tomorrow’s paper.
