Start the ball one click to the right, then reposition your paddle 2-3 clicks to the right to intercept the ball as it bounces off the unbreakable bricks. Strike the ball on the right half of your paddle and try to send a slightly angled shot into the right wall at about the level of the bottom-most row of unbreakable bricks. You can also start the ball off two clicks to the left, following the same principle.
This should dislodge one or more of the exposed capsules. Often, multiple capsules will be dislodged and will be falling simultaneously, so keep a close eye on which ones you intend to grab.
If you get trapped under the row of unbreakable bricks and need help getting out, read these instructions.
If you get the Gun, try to destroy three of the five low-hanging unbreakable bricks. Destroy either the left-most three bricks or the right-most three bricks; this gives you a clear channel to the top of the board. Don’t destroy the middle three bricks.
Multi is helpful when the ball is moving fast. I usually avoid it when the ball is moving slowly, because there are many capsules on this level and dislodging them all at once can be confusing.
