Cookie Craze is a temporary event that is only available for a certain time in the game. With every match-3 level you beat, you get to bake cookies. If you cook the required amount of cookies before the event ends, you get the final prize! But there are other prizes along the way, too. If you beat a level at first try, you get to bake more cookies.
This event is available to players who are at level 25 or above.
With each level you win during the event, you get a star AND get to bake cookies.
