Slither.io game centers on playable snake characters. This is the game that combines Agar.io and classic Arcade where you have to take control of the snake and move it around the map to hunt for the glowing pellets, eat them up to gain the size and try to avoid running into other snakes. One of the questions that players usually ask is how to speed up the snake when you control it. To accelerate, you need to click and hold the left mouse when your snake reaches enough length because speed burst will cost your mass, also; you can utilize up arrow key too. If you play the game on mobile devices, you need to double tap it to go faster. You will go at normal speed again if you release the mouse. That’s all that you have to do when accelerating! Have fun!
