1-Up icons are rare collectibles that instantly grant Sonic an extra life. They are often hidden in secret areas, off the main path, or require a specific Color Power to reach. While collecting 100 rings also gives you a 1-Up, finding these icons can be a quicker way to stock up on lives, especially if you're struggling with a particular level. Keep an eye out for them in suspicious-looking alcoves or after using a Wisp to open a new path. Having a good stock of lives can make challenging levels less frustrating.
