The game is primarily monetized through in-app purchases (through either a credit card, iTunes credits or Google Play credits); players begin with five "lives", lost whenever a level is failed. This applies to all of King's games. When they are exhausted, users can either send requests to their Facebook friends for more lives, wait for them to replenish themselves (a life is restored every half-hour), or purchase them. At certain points, primarily at the start of new "episodes", users must also either purchase, or receive a request from at least three friends before they may access the next set of levels. Boosters, to make the levels easier, can also be bought using in-app purchases.
While the game includes freemium content, 97.7% of people playing the game are playing for free, while only 2.3% pay.
Once all levels in an episode are completed, the next episode (starting at episode 3) is locked and the player must either get three friends on Facebook to send them "tickets" to unlock the next episode, it can be unlocked directly through the in-game store, or occasionally the game will allow the player to move on for free if the player has not been able to unlock the next area. If the game is not linked to the player's Facebook account, a new level can be unlocked by playing a Mystery Quest, a random previous level with a higher point threshold for winning. Three Mystery Quests must be completed before the next episode is unlocked, and a player can only complete one Mystery Quest in a single 24-hour period. Recently the option to unlock episodes by playing mystery quests is only available after several days have passed and no help is received through friend requests on Facebook. Other than waiting the time period until mystery quests are available, using in app purchase is the only way to unlock episodes.
