Snake Island 3D is an snake game with a unique merge feature that has fun, vibrant graphics. A player directs an animal around on a playfield on Snake Island in a global multiplayer setting. Their primary objective is to grow their animal to the longest length possible by eating fruit without sliding into another animal.
The player starts with a snake. If they perform well, they can upgrade to other animals (i.e corgi, leopard, panda, dragon, platypus, rhino, unicorn, alpaca, dinosaur and alien). They perform the upgrade by using coins they receive whenever they win to buy a new skin. That said, they don't simply buy it. Instead, they buy the opportunity to merge together two of the same type of animal on a separate mini playfield to create a new one. For example, two snakes create a corgi and two corgis make a leopard.
The game offers several modes and rewards. The player unlocks these areas by winning in each setting. When they win, they receive coins, gemstones, stars and medals. They also receive coins and other rewards like abilities and early trials of skins directly and via treasure chests and lucky spin wheel opportunities by watching advertisements.
