“The "green mode" you're referring to in the Simon game is likely the **TRAINING mode**. In this mode, mistakes are allowed; if you press the wrong color, the game will show you the correct series again, giving you another chance to follow the sequence¹. This mode is designed to help players practice and improve their memory without the pressure of the game ending after the first mistake. It's a great feature for those who are still getting familiar with the game or for those who want to achieve higher scores by memorizing longer sequences. Enjoy playing!
