How to Play Sonic The Hedgehog
Sonic The Hedgehog is a 2D platform game wherein you control Sonic, a blue hedgehog that can run at lightning speed. Dr. Robotnik has filled each act with traps and robotic animals. Race through these obstacles, avoid deadly enemies and spikes, and destroy robots to free the trapped animal. Collect all Chaos Emeralds and defeat Dr. Robotnik to save your animal friends!
At the start of the game, Sonic has three lives. Sonic loses a life if he falls into spikes, collides with enemies without having any rings, or runs out of time. The goal is to complete each act or level within the ten-minute time limit!
Tips, Tricks & Strategies
Adjust the Controls
The default controls are quite hard to navigate, especially if you’re not a retro game player. Thankfully, you can change the controls by hovering on the bottom left of the screen. Click on “Controls Settings”, then press the keyboard controls. Press in the keyboard the control you would like to swap the default with, and then press “Update” when done.
Collect Rings
Think of collecting rings like an extra shield for Sonic! If Sonic holds at least one ring, he won’t lose a life when he collides with an enemy or a hazardous obstacle, although all his rings will scatter. Sonic may pick up these rings quickly before they disappear. Don’t forget to collect 100 rings to receive an extra life!
Use The Spin Attack
Sonic’s main attack is a spin attack, wherein he curls into a ball and spins his body, colliding with enemies and obstacles. Use this attack to destroy robots as well in order to save trapped animals.
Act Quickly
Remember that you only have 10 minutes per act before you lose a life! Keep an eye on the timer below your coin count. Look out for star posts as well that act as checkpoints in the game. This is where you’ll respawn if you lose a life.
