In Bubble Witch 3 Saga, you aim and shoot bubbles to match three or more of the same color. The objective is to clear the board by popping all the bubbles while completing specific level goals.

You earn stars by completing levels with a high score. Each level awards up to three stars based on your performance, such as the number of bubbles you use and the level objectives completed.

Power-ups can greatly enhance your gameplay. To use them effectively: 1. Select a power-up before starting a level. 2. Combine power-ups for better results. 3. Keep an eye on the board for optimal moments to activate them. 4. Utilize them in tougher levels.

To unlock new areas and levels, you must complete the current levels successfully. As you progress and reach certain milestones, new maps and challenges will become available for you to explore.

When you run out of lives, you can wait for them to regenerate over time or receive extra lives through daily rewards. You can also ask friends for lives to continue playing without waiting.
