Giraffe Evolution lets the player collect, combine and evolve giraffes. Players start with a small giraffe delivered within a box. Every few seconds another giraffe arrives in a box and after getting it out of the box by tapping on the box, the player can combine two giraffes of the same type. When one giraffe is dragged to another giraffe of the same kind, both combine into one giraffe of the next evolution.
All giraffes are pooping regularly, which earns the player gold coins. Gold can be used to buy more giraffes, upgrades like a tractor to collect the poop while the player is not playing Giraffe Evolution, and new outfits for the giraffes. Some outfits and upgrades can only be obtained with the premium currency diamonds which can be found in small amount or they can be bought with real money.
When giraffes reach specific evolutions, new areas are unlocked for the higher evolved giraffes. And later even aliens are interested in the giraffes.
Giraffe Evolution is free-to-play and is available for devices with Android or iOS.
