Freak out in the lab, let your imagination run riot, merge the DNA of different animals and create the ultimate mutant runner, then test your experiments by letting them loose on a varied range of obstacle courses to race against other multi-limbed freaks of nature in the ultimate competition in evolution where only the fittest will survive.

A fun running game with a freaky difference, Merge Animals 3D combines strategy, lateral thinking and crazy science to fire your imagination and get your adrenalin pumping. Demonstrate your evil gene-ius, perfect every pixel of your runner, and put them on the track to evolutionary success.


• Survival of the fittest – over 20 different levels with hugely varied obstacle courses, different aspects of which favor different advantages in evolution. Mod your mutant runner carefully in the lab, and if you don’t win first time, try merging other genetic variations to produce the right combination for the course. Keep on experimenting!

• Lucky rabbit’s feet – inject your runner with the DNA of over 10 different animals to create hundreds of genetic variations, each with their own unique genetic advantages that will help overcome a specific element of the obstacle course. Give your athlete the wings of an eagle to soar above the competition, the arms of a spider to scramble over rough surfaces, a giraffe’s neck to stretch across the finish line, and a pair of rabbit’s feet just for luck.

• Designer DNA – colorful graphics and cool character design merge with imaginative obstacles and eye-catching animation to make the world of Merge Animals 3D a beautiful game right down to the last pixel, as well as fun and vibrant place to spend your time as you play at mad scientist in style.

Hilarious game

I don’t know what the devs were on when they made this but I’ve enjoyed playing it. I don’t usually play mobile games really because the ads are such a pain but this one was actually good and unique. I still would recommend to tone it down on the ads but they’re not as bad as I usually experience nowadays with the money grabbing world of mobile games. Airplane mode works lol and there are strong incentives to watch ads when you want to like when you’re unlocking a new animal. Also it got really easy really fast but I can’t say much about that because I haven’t explored further to see if there are any other gamemodes or things like that.

I don't like crashes! ,

Very fun app and entertaining 1 but ads.

Hello developers im a beta user and i like to post my honest comments and experience with this app so far.

1) please remove ads to unlock new merging animals liquids
2) please remove ads in when you need to use 3+ to merge the liquids.

3) And if those ideas dont sound good enough make a 1-2$ ads free skiping option or…

4) just remove the required to watch ads for 3rd+ liquids and make 1-2$ free of ads internationally/skip ads option.

Its just too much ads needed to just enjoy the game… not a pleasant experience to be honest.

5) overall really appreciate for making a fun app.
It just needs more work and had high potential!
