BOXBOY! + BOXGIRL! may start off pretty simple, but it gets tricky pretty quickly. So let’s get started on the single-player segment: World 15 Slam Them Down!

As there is a lot to cover, you may stumble across a solution to a level that may either be incomplete or not to the best it could be. If you have any solutions, please be so kind as to email us at team@switchaboo.com and we’ll be sure to provide credit if we use it.

World 15-1

Boxes Used: 10

Do as the the tutorial video suggests and make two vertical boxes and slam them down to the red silhouette.

Next, make two horizontal boxes (with one hanging over the gap) and slam them down to the blue silhouette.

For the third section, make a three-boxed backwards L and slam them down.

Lastly, make a three-boxed forward facing L, throw it down into the pit and slam them down twice to be able to get the Crown.

World 15-2

Boxes Used: 15

Make four boxes to the right, with the leftmost box on the corner of the ledge and slam them down twice to cover the blue silhouette.

For the first Crown, make a forward-facing S (right x2, up, right) and throw it as right as possible, allowing you to grab the Crown and slam the boxes down to cover the red silhouette.

Next, make a three-boxed backwards L and place the leftmost box on the corner of the ledge. Slam them down once and proceed onwards.

For the second Crown and the door, make four boxes in this order: right x3, up and place the leftmost box on the corner of the ledge. Stand on the middle box and slam down three times to collect the Crown and proceed to the door.

World 15-3

Boxes Used: 10

Make two horizontal boxes to the far right and slam them down twice so that you can fall down and walk to the left.

For the Crown, stand on the upper ledge on the right facing left and make four boxes in this order: left, down, left x2 so that the leftmost box has no ground beneath it. Then slam them down all the way, drop down and grab the Crown.

For the second Crown and the door, jump to the right side of the gap facing left, make four boxes in this order: left, up, left, up (like one of the worst Tetris pieces) and drop it into the gap in the ground. Then slam them through the ground, grab the Crown and get to the door.

World 15-4

Boxes Used: 13

Make four boxes to the right, with the leftmost inline with the blue silhouette and the rightmost having no ground beneath it. Stand on the rightmost box and slam down twice.

Standing on the left ledge, make five boxes in this order: right x2, up, right x2 and throw them so that they hook on to the right ledge. Slam them down twice, grab the Crown and proceed onwards.

Make four boxes in this order: right x3, up and throw them onto the floating block with the rightmost box on it. Slam them down through the block, grab the Crown and make for the door.

World 15-5

Boxes used: 11

Make a staircase of 5 boxes (two right, up, right, up), with the lowest one above the blue button and the rest to the right. Climb to the highest point of the staircase and slam it down three tiles, until the bottom box overlaps the button.

Past the gate, face left and make another staircase, but with an extra box on the end (two left, up, left, up, and left). Place it so the lowest box is above both buttons, half way between them. You should be able to stand on the leftmost box and slam them down four tiles, because of the half a box sticking out above the platform. Collect the crown and head for the door.

World 15-6

Boxes Used: 15

Make a three-boxed backwards L and slam it down twice to block the laser. For the next section, make another three-boxed backwards L to use as stairs to get up to the section to the right. Then make five boxes from right to left as stairs (left x2, up, left, up) and slam them down so that the laser is blocked and there is still a step up for you to get back up and over via.

For the last section and the Crown, make a four-boxed forward facing S (right x2, up, right) and place it in line with the three lasers. Slam it all the way through, grab the Crown and make for the door.

World 15-7

Boxes Used: 10

Stand as far right as you possibly can, teetering on the edge, and make three boxes in this order: left, down, right. Now that you’re standing on top of a single box that has no ground beneath it, slam it down four times to get through.

Next, make three vertical boxes and throw it as far left as possible. Jump onto it and slam down on it twice, covering both lasers. If you threw the boxes to the left far enough, you should be able to drop down and grab the Crown along the way.

For the last challenge, stand on the right facing left, make four boxes in this order: left x2, up x2 and position it so that the right box has no ground beneath it. Stand on that right box, slam down twice, jump right to grab the Crown and make for the door.
