It's poppin' time! Your goal is to remove all the bubbles from your screen. Aim by moving your mouse, then click to launch a bubble in that direction. To clear bubbles, the color of the bubble you fire must match the ones you're targeting. When three or more bubbles (including the one you fired) of the same color connect, all connected bubbles of that color will be removed. Any bubbles that have nothing to stick to will also fall down, scoring more points for you.

TIP: If you want more help while aiming, click the gear icon in the bottom left and enable the "Reticle" option. This lets you hold down left click to show the full trajectory of your bubble.
