Add friends through the "Social" tab to earn gems. Gems can also be traded between players.
Habitats
Build habitats that will allow you to generate the most mana Orbs. As you gain experience, the maximum number of habitats that you can build will also increase. Build new kinds of habitat, including those which can generate the maximum mana orbs. The fire habitat can also be made, but they are more expensive than the earth habitat.
Layout
Arrange your buildings wisely to manage the space in your territory. Clear out obstacles such as rocks and trees to make more space. Place buildings close to one another. Also consider placing your buildings in the edges of your territory until you use all the space available.
Wooparoos
Do not spend your currency to purchase new Wooparoos. Instead, breed the Woopacross you already have that are at least level four to get a rare crossbred Wooparoo. When breeding Wooparoos, you will be able to tell if you will be getting a rare variety by checking how long it takes to breed and the time that the egg requires to hatch. The longer the time, the better the chance of a rare Wooparoo.
