There is now a third version of Babel Rising for Android. The newest one is called Babel Rising Sponsored, and it removes the in-game purchases that some players disliked about the first two versions. You won’t see any options to spend real money unless you want to remove the ads. That particular purchase is only $0.99.
You still need to earn in-game currency to unlock certain levels and upgrade powers. You can earn Babels by completing levels and objectives, or by fulfilling suggested promotions. These promotions involve downloading certain apps or signing up for services.
Now that you have nothing to lose, go ahead and try out Babel Rising.
