The simple game is just about pointing and clicking on bubbles that drift by. Click a bunch of like-colors in a row, and rack up a bonus score that's activated when you pop a different-colored bubble. Miss the bubbles completely, and the count-down timer jumps ahead, moving closer to the end of the game. The only other catch is that your potential points and time keep rising with bubble-popping combos, but they aren't added to the game until you break the run. Get too greedy, and you'll run out of time.
