Sonic the Hedgehog Extra Life (Any Level)
At the end of any level, if you have less than 50 rings and therefore cannot get to the bonus level, run through the turnstile and then stop and jump straight into the air. If the turnstile is off the screen when is stops spinning, when you come down it should show a picture of Sonic and therefore give you an extra life.
Sonic the Hedgehog Extra Life (Level 1)
To get an extra life at the beginning of the game, walk (don’t run) down the first ramp. And after you have walked over the edge of the ramp find the second tree. Go to it and jump. An extra life power-up will fall!
