[Update: I figured out more of the rules of the game regarding how and when the bubbles drop. That knowledge greatly increased my ability to stay in the game. Consequently, my high score jumped significantly.]
Here's a fun flash game. It is a remake of an old coin-op game that I used to play. Bubbles. Basically, you just use your arrow keys to move the cannon and then the space bar to shoot the bubble up. If it hits another bubble of the same color, and a chain is created that is more than 2 long (3 or more), then those bubles disappear. Simple, yet super fun. [via Ongoing]
