How do I updte score to nex layout?

on my game play layout i have a score which is updated on collision with another object and after game over i want that score should be shown to Restart layout please help me.

How do you save this score?

If is using an global variable, that should be really easy to update your score.

There are many ways to do that: using an text to show this score global variable, using an sprite font to show this score or even an normal sprite with many frames to show an specific frame depending on your final score.
