This trick will only work if you are down to your last life, so make sure you're paying attention! It is not possible to get unlimited lives in the Facebook version, as everything is run a central server. Any site claiming to provide unlimited lives is a scam. When you are down to your last life, open up Candy Crush in another tab in your browser. Go to Facebook in the other tab and tap "Candy Crush Saga" in the sidebar to the left.  Don't start playing the level.  Just get it ready. If you lose your last life in the first tab, you can switch to the second tab for one more go.  If you lose your last life, immediately close the tab before the match is over and open Candy Crush Saga on Facebook in a new window.  You can keep doing this as long as you open a new tab and close the old one before the life counter drops to 0.

How would you rephrase that briefly using Vietnamese?
