<P> `` Lives '' serve as a mechanism to throttle how often new games can be started , and also provide an in - app revenue opportunity for the developer . Each time a player starts a game by pressing the New Game button , or accepts a Facebook friend 's request to play against them , they are charged a Life . A player can have as many lives as they wish , and as they spend lives , the game will automatically replenish one life every hour , provided they are below 5 lives , until the player returns to a full charge of 5 lives . A heart icon on the app 's main screen shows how many lives the player currently has , and if they have less than 5 , a timer will also display that ticks down in real time to show how long until the next replenishment . If the player runs out of lives , they must wait for replenishment before they can start any new games or approve a new game started against them by a Facebook friend . A player who does not want to wait can either request lives from their Facebook friends , or can buy lives through an in - app purchase . </P>
