Yes. The game is built to work on touchscreens as well as desktop. On a phone or tablet you drag your finger to aim and lift it to fire; on a computer you aim with the mouse and click to shoot.

You clear a level by removing every bubble from the board. Match three or more bubbles of the same colour to pop them, and watch for bubbles hanging underneath — when the group holding them up is popped, they fall as well, which is the fastest way to clear a board.

The level ends. The wall of bubbles advances downward as you use up shots, so if you spend too many shots without clearing bubbles it will eventually cross the bottom line. Popping large groups and triggering drops keeps the wall in check.
