High score for endless runner.

Hi
I am creating an endless runner game, the player will pick up pebbles that add 1 to a total score shown on the HUD which is then reset when the player dies, this is what i have implemented so far, however i would like to have a high score system were the best score achieved by a player is shown on the in game HUD , however i have no idea how to do this. I have tried several tutorials that show how to make save games however these haven’t helped. if anyone would be able to walk me through this process it would be greatly appreciated.

Bellow are some i have tried following,
