Lost Island HD, aka Tiny Tribe, is like an iPhone and Android game version of Lost, except a little more light-hearted and less full of weird numbers and hatches. But like the television series, Tiny Tribe puts you in charge of a series of explorers whose plane crashed on a small island full of discoveries, so while you’re there, you might as well go deeper and see what you can find. Diamonds (or Gems, depending on what mood the game is in) are the premium currency of the game, and they are the only one of the currencies in this game that actually costs real money to buy. Nobody wants to do that, though, so read on to find out how to get free Diamonds/Gems!
Each time you turn in a collection of three items, one of the prizes you will get for it will be a diamond or multiple diamonds. In addition, some of the achievements that you can accomplish in the game will earn you diamonds as part of the reward. Not all of them will, but some of them will, generally the more advanced ones in the game. Go to the treasure chest icon in the lower right corner of the screen and tap on it to check both your collection progress and your achievement list to see what you need to complete next.
Oftentimes, quests will pop up in your quest bar that offer you diamonds as a reward upon completion. Usually, the quest will have you do something “social” such as “like” the game on Facebook or post an invite to friends. Do so, and you will earn diamonds as a bonus when you complete the quest.
Also, enter the promo code of another player (or have them enter yours) and you can earn bonuses that include diamonds. To get your promo code, tap on the lower left icon (the one that looks like a gear) and hit the Promo Code button. Start sending it around and start finding other people’s codes to enter.
Lastly, tap on either the Bank, or on the above-noted “gear” icon and hit “Free Gems” and you will be able to complete a whole bunch of offers on Tapjoy that earn you free diamonds. In addition, when you take the offer to “sign up for Tapjoy” or “come back to Tapjoy”, a secondary list of free offers will pop up for you to complete. Each one that you complete earns you a designated amount of gems, and considering how many offers there are, you can earn a LOT of diamonds this way.
