Sparkling Happiness is a may-follow trick-taking game, but only until you win your first trick with a card offsuit. You can follow suit as a normal must-follow game, but you win more points for winning tricks offsuit. When you win your first trick offsuit, you must follow suit after that, and then you cannot win a trick with the color that you won the offsuit trick or tricks. If you do, you lose both tricks. Also, you need to finish the round with an exact number of tricks. How you organize your things and get rid of what doesn't sparks happiness is up to you. —description from the publisher
