How are the crossword scores calculated?

You get 10 points for each correct word completed. Revealing letters or words will cost you points. 

For each square you reveal, you lose 1 point(s), but you can still get the 10 points if you get the word right. You get no points for a word if you reveal it entirely. 

The target time to complete this puzzle is 15 minutes. When you complete the puzzle, you will get a bonus of 15 points for every full minute under the target. There is no penalty for going over the time limit.
