Cookie Crush Christmas 2 is a matching game where you have to connect at least three of the same sweet treats and clear all levels.
In this game, you have to drag and swap sweet treats to match three or more of the same ones horizontally or vertically and clear them from the board. Your goal may be different in each level. Most of the time, you have to clear certain sweet treats from the board within certain moves. The game is over if you can't complete the goal.
If you can match more than 3 sweets, you can gain boosters that can help you clear more sweets.
