How does rewarded video work?

Bubble-Pop-Ball reward video button appears in case you cannot pop all bubles in 60 sconds.

When you watch the award-winning video, you have the right to continue the game from where you left off with +20 seconds time.

If you cannot pop all the bubbles in the game after 60 seconds, the "Game Over" window appears and you can see the award-winning video with the "+20" sign there.

It may be helpful to learn the movement patterns of some monsters in the game. To see the enemy list, see this page:
