Each level will have a goal for you to achieve, so you can pass to the next.
Though some levels will have a specific task, most levels will need you to reach a score target to make your way through the map.
When you link letters and create words, you'll earn points according to the length of the word and the value of the letters.
There are ways to increase your score, like including the gold and silver tiles in the word you create. Make the most of the elements in the level to hit those high targets!
