Your goal is to pop as many numbered bubbles before they cross the line at the bottom. Left Click & Drag to aim, then release to shoot. Launch the bubble at the ones that match to make them pop. Click on the cannon to switch the next bubble in case that's the better move.

This is a cozy-looking game, but don't let that fool you. The orange bar at the top of the screen shows how long it will take until the bubbles move down one row. If any bubble touches the line at the bottom, it's game over.

You'll earn coins for every match, so try to go for big combos. You'll get even more coins when you level up. Spend those hard-earned coins on these powerups:

• Bomb - Pops any bubbles it sticks to
• Shuriken - Slices through bubbles in the direction of your aim
• Lightning - Pops all bubbles in a row

Click on the powerup icons at the bottom of the screen to use them.

TIP: Don't have a good shot on the bubbles? Try to bounce your bubble off the sides!
