The objective of Line Drop is to line up three or more of similar colored gems within a minute. Clearing gems will increase your chain combo gauge. Filling your gauge will make a spirit appear and when the spirit is lined up with the same color it will clear all of that color from the board. If the player clears three spirits in a row, they will enter Bonus Fever which ups the points earned. Each round costs the player one heart while playing in mission mode will only cost one heart until the player loses and has to continue, diminishing another heart. Hearts will be replenished after an eight minute period but can also be bought with in game rubies or from friends. Rubies are obtained by completing various tasks or simply by entering the app. Rubies also allow the player to purchase items
