Merge Animals 3D is a bizarrely entertaining take on the 'evolve and race' subgenre. The game asks a simple question: what happens if you give a human the legs of a cheetah and the wings of an eagle? The 'lab' phase of the game is where the fun lies. Injecting DNA into your runner to overcome specific obstacles—like gills for swimming or claws for climbing—adds a light layer of strategy to what is otherwise a standard auto-runner.
The race itself is a colorful display of evolutionary chaos. Seeing your mutant runner outpace opponents by growing a giraffe neck or spider legs is consistently funny. While the gameplay loop is quite repetitive and the ads can be frequent, the sheer variety of animal combinations keeps you coming back to see what the next unlock will be. It’s a great example of a 'hook' game: weird enough to catch your eye and satisfying enough to keep you playing for a few hours.

► RELEASE THE MAD SCIENTIST WITHIN…
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.
► WIN THE MUTANT RACE
• 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.
► MIX THE ULTIMATE GENETIC COCKTAIL
What do advances in gene science mean for the future of the human race? In this crazy casual game, the chance to make some freaking awesome changes to the human body with just a few jabs of a needle.
Take advantage of these amazing advances in bio-engineering, download the game now, and merge animal genes to create the ultimate mutant athlete in this highly original running game that combines fast-paced races with strategic puzzle play as you combine the features of different animals in the lab to produce the best runner for each individual obstacle course.

Merge Animals 3D is a creative racing game where biological engineering is the key to victory. Before each race, you visit the laboratory to modify your character with DNA from various animals. Different body parts grant different powers, such as wings for flight or shells for defense. Choose the right mutations to navigate the track's hazards and cross the finish line first.
20+ animals with unique traits
Dozens of challenging race tracks
Fun laboratory customization
Bright and wacky 3D graphics
Analyze the track before the race starts. If there is a lot of water, prioritize shark DNA. If there are high walls, go for spider or monkey DNA.
Tap and hold the syringe to inject DNA into specific limbs. You can mix and match up to 10 different animal traits to create a unique runner.
The Cheetah DNA provides the highest flat ground speed boost in the game.
