To play the game, just swipe the letters with your finger to appear in a word you want to enter. For example, if you want to enter the word "CAT," you need to put your finger on the letter C, then move your finger to the letter A without removing your finger from the screen, then move your finger to the letter T and only after that you need to remove your finger from the screen. At that point, the game will check whether the word CAT fits anywhere on the level. The point of the game is to guess all the words on the level. Empty white squares at the top half of the screen hint at how many letters each word you need to guess has.
