This game is easy and quick to learn, but then becomes difficult to master! Each level as you advance gets more and more difficult to clear with matching colors. Using less shots allows me to score higher and clear the level quickly, which is a classic take on the game. Clear bubbles to a certain score to advance to the next level The player need to match at least 3 bubbles of the same color in order to eliminate them. Tilt the shooter to aim carefully at the color bubble that matches the one I'm shooting. I play by blasting matching colors of bubbles through multiple levels to advance forward. I often lose hours of my day playing this online Bubble Pop! This classic version of the highly addictive game have me glued to your computer screen for most of the day.
