If you get stuck, use smaller words to help move to the next level. Although you will not get a good score from them, it will help your speed and prevent waiting for a longer word to form and allow you to earn points consistently. If you can use a large multiplier in a smaller word it may be worth more points than a plain larger word. In well-climbing levels, you must play for speed and not points. Spell quickly, using shorter words to keep moving.
