Try starting the ball one click left. The ball will hit the bottom row of unbreakable bricks, so quickly slide your paddle all the way to the left wall. Hit the descending ball off the right end of your paddle and hopefully it will travel up the chute and, after bouncing around a bit, dislodge one of the two capsules. You can also try starting the ball at the default position (zero clicks), which should send the ball up the center chute.
If the ball ever travels back down the center chute, position your paddle in the dead center of the board. Watch as the ball exists the chute, then move your paddle left or right to intercept it. Try sending a slightly angled shot back up into the chute. Hopefully this will bounce around dislodge one of the two capsules.
If you get the Gun, use your first bullet to destroy the unbreakable brick that’s directly under the remaining red brick. Then use your second bullet to destroy the red brick and end the level.
