Rewarded video ads to continue game

I'm creating a flappy bird type game by following [this][1] unity tutorial. I now want to integrate videos ads. Once the player dies, the user should have the option of watching a video ad and then continuing from the place where the player died along with the same score as well. How can I achieve this. Most of the tutorials I have seen on youtube allow the user to get some points rather than allow him to continue from where the player died.
