To clear the Birthday Cake, make a match of one of the 4 colors (Red, Orange, Purple, and Green) to clear 1 piece of cake. There are 2 pieces per color, 8 matches need to be made in total. Matches can be made anywhere on around the cake. Once all 8 pieces have been removed the Birthday Cake will remove 1 layer off of the board.

Birthday Cakes are introduced in Level 1621.
