When you play every day you can earn 5 points, and for each consecutive 7 day streak you get 50 points. You can also buy points at a rate of 10 points for every $1 you spend, and these points can be traded in for in-game currency.
The Kabam Rewards badge will show up in any participating game. The program is only available on iOS 6.0 and above though, so you might have to update in order to join.
Fruit Ninja is about to get its biggest update yet to celebrate its second anniversary on Thursday, May 24th. The key new element in the game appears to be that players will now be able to earn an in-game currency, called starfruit, that can be used to buy new powerups from new characters Gutsu and Truffles, introduced in the new trailer produced by People’s Republic of Animation. Powerups and new “super fruit” like berry blasts will be available to help players raise their high scores. New powerup peaches will add extra time to Arcade and Zen modes, making higher scores even possible. As well, a new bomb deflect powerup is available for skilled ninjas.
As well, in celebration of this new update and the 2-year anniversary of the game, Fruit Ninja is temporarily being given away for free from their Fruit Ninja Anniversary page, where a promo code for the iPhone/iPod touch version can be generated for a limited time. The update will arrive for both versions of the game this Thursday.
