Fairies is a match three puzzle game. Using your mouse, slide the rows of fairy jars until you get a group of three or more of the same color. This will then release their fairy dust, which is collected and weighed. When the scale is full, the level ends.
There are four modes of game play. Adventure moves you from one level to another, where the backgrounds can change, and it is timed. Classic mode still has the scale but it is not timed. Relaxed mode has no scale or timer. You just play. Playback mode has six groups of fairy jars. The computer will light them and play a tune in a certain order. You must then click the same order.
