Bubble Crack

In general, if you haven't already figured it out, you play the game by shooting balls into the arena. When your ball completes a set of 3 balls of the same color, all balls in that group of same-colored balls disappear.
Try it a little, it makes sense.
After the same-colored balls disappear, any unsupported balls disappear as well. The top row of balls is always supported, other balls are supported only if there is a path of connected balls between them and the top row.
Again, this will make sense after you see it.
The top wall drops one notch after every 6 balls you fire. At such time as the arena balls cross the bottom arena line (nominally red), you lose. If you clear all of the balls out of the arena first, you win and go on to the next level.
If you do not fire a ball within 10 seconds, the computer will fire it for you, regardless of where it's aimed.
You get 10 points per popped ball in the original triad.
The score for each unsupported ball increases based on the number of balls popped. The first extra ball is only 10 points, 2nd is 50, you get the picture. Popping large numbers of unsupported balls is the fastest way to high scores. If you clear a level in under 60 seconds, you get a bonus based on the number of seconds left that maxes out at 50,000 points.
