Playing the game is easy, simply register and visit the quests page. Each player starts with 5 energy to do missions with and regains 1 energy point every 3 minutes. Quests work on a timed basis, first you click Do Quest, wait until the quest is complete, and claim your quest reward. In order to unlock new quests, you must complete 100% of the previous quest.
Some quests do not unlock until later in the game, be sure to check different locations for new unlocked missions..
