Moved to General Discussions since this isn't a Fiesta-related question. =]
Basically, you need to click on the pieces to rotate them as they appear, and join them up into a loop. Once you have connected some pieces together into a loop, they will disappear. Your aim to is get rid of as many pieces as you can before the whole box is filled up with unused pieces. The more pieces you're able to join together, the better your score.
