BOXBOY! + BOXGIRL! may start off pretty simple, but it gets tricky pretty quickly. So let’s get started on the single-player segment: World 13 Piercing Drill Blocks.
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 firstname.lastname@example.org and we’ll be sure to provide credit if we use it.
Boxes Used: 9
Follow the tutorial instructions and jump on over. Next, jump onto the drill box and make a three-boxed backwards L to use as stairs.
For the third section, make a single box and throw it onto the spikes as far right as possible. Wait until the drill platform goes down allows you to jump across.
Make a three-boxed backwards L to use as stairs and jump onto the drill platform just as lands. Then make two vertical and throw them onto the spikes. Jump to the door and collect the Crown along the way.

Walk onto the drill platform and at the end, make a three-boxed backwards L to use as steps up. For the next section, jump down onto the drill platform and make three boxes horizontally and move across.
Lastly, jump down onto the drill platform when it gets to the end. Make three boxes to the left and jump so that the far-left box hooks onto the drill cannon. There, you can pull yourself in and grab the Crown. Ride the drill platform back, make a three-boxed backwards L, place it just before the spikes, climb up and get to the door.

Wait for the first drill platform to drill into the wall and make a four-boxed right hook to make your way up. Then quickly do it again.
For the second part, wait for the drill to stick into the ground and make a three-boxed backwards L to use as steps up to the top. Then make four boxes to the right above you and jump over to the right to hook onto the ledge, collecting the Crown along the way.
Lastly, throw a single box onto the spikes and jump across. Make a four-boxed left hook and get up to the left drill platform. Then make three boxes to the right above you (up, right x2) and jump to the right to get to the Crown as shown below.
Ride the platform drill to the left when it comes out. When it reaches the end, make another four-boxed right hook, pull yourself up and make for the door.
Boxes Used: 8
Do as the tutorial video shows, but with only two boxes, and then place them down to the right but so that the leftmost box is teetering on the ledge.
Stand to the right of the spikes, make three vertical boxes to the left (left, up x2) and shoot it to the left so that it covers the red button. Run through the opening before the drill box disappears.
For the Crown, stand at the topmost section, make a three-boxed L above yourself (up, left, up). Have the drill platform top go into the topmost box and push it into the button. Now jump up and grab the Crown as shown below.
Before the drill platform disappears, make for the door.
Boxes used: 13
Make a horizontal line of 4 boxes left, then as the drill box comes down, jump out over the spikes to catch it, but make sure you land back on the ledge.
Stand just to the right, below the first crown, and make one box left, then three more down, pushing yourself up so you can hop and get the crown. Catch the drill box on the left at the top of the tower of boxes, and place all boxes over both red buttons (even though only half a box will cover each button, it will still activate).
Make 5 boxes: three right, one down, one right, and let the drill box land on the right-most box. Place it over the blue buttons and you will be able to jump onto them to collect the second crown.
Boxes Used: 25
Jump onto the drill platform as it shoots across and make a four-boxed right hook to get up to the right ledge. Then make a five-boxed left hook to get up to the next ledge from the right of it.
For the Crown, stand on the drill platform, make a four-boxed left hook from the left of you (left, up x2, left) and jump to the left in order to hook onto the ledge. Pull yourself up and you’ll grab the Crown along the way.
Next, when the drill platform goes past, make a four-boxed left hook platform above yourself and pull up to the left ledge. Jump onto the platform drill and when you’re in the gap, make a three-boxed even left hook above you and jump to get up to the Crown.
Now wait for another drill platform, jump down to it and make a five-boxed right hook to get up to the door.
Boxes Used: 16
Jump up, make two boxes vertically above you, jump up again to catch the drill into the top box and have the drill platform fall onto the blue button.
Next, drop down onto the bottom-right ledge and face to the left on the ledge. Make four boxes downwards so that the bottom box catches the drill. Jump and throw them to the left so that you can jump onto the boxes and grab the Crown (at the same time, the drill platform will fall onto the red button).
For the last section, make two boxes to the left and jump to grab the Crown whilst the leftmost box will land on the ledge to pull yourself back onto.
Now make four boxes to the right and catch the drill on the rightmost box. Now place it down onto the ledge so that the blue button is pushed in, allowing you to make your way down to the bottom. Now stand so you’re teetering over the spikes and make four boxes above yourself. Have the next drill go into the boxes and place them down so that they’re pressing in the red button for you to finish up World 13.
