Marble Sort Level 216 Guide: The Crossed Lock and Key Trap

Marble Sort Level 216 is a massive headache if you do not spot the crossed keys right away. You are staring down a board heavily choked by two thick chains. The dominant colors you need to juggle early on are Dark Blue, Orange, Red, and Light Pink. But color sorting is actually your secondary problem here. The real issue is board access.

Take a quick look at the top. You have two Panels marked with a "2" guarding the upper corners. Below those are your locks. You are blocked by a Brown Lock and Key chain on the left and a Purple Lock and Key chain on the right.

Here is the trick that ruins most runs. The Purple Key is stuck on a Light Pink box on the left side of the Top Tray. The Brown Key is stuck on a Red box on the right side. You have to play crisscross to unlock the upper half, all while dodging a massive block of gray "?" Mystery Boxes dead in the center.

The Crossed Key Pattern in Marble Sort Level 216

The layout here is totally unforgiving. The Top Tray sits with a Dark Blue box and a Cyan box fully exposed at the bottom lip. Behind them sits a row containing Purple, Dark Grey, Orange, and Red.

The initial set of lower Boxes asks for Light Blue, Dark Blue, and Orange. Your brain will immediately want to start digging down the sides where the Arrow Boxes are waiting. Do not do it. Those down-pointing Light Blue and Yellow Arrow Boxes are pure bait right now. If you dump them onto the Conveyor Belt too early, you will run out of space before the matching lower Boxes spawn.

Instead, the entire level revolves around grabbing those two keys. The Purple Key sits on the left on a Light Pink box. The Brown Key sits on the right on a Red box. You must reach them. The left side of your Conveyor Belt will get heavily crowded first because you are forced to dump unmatchable colors just to dig down to that Light Pink box.

The center of the board is a massive cross of Mystery Boxes. These are terrifying. You cannot know what color they hide until the box in front of them clears out. If you blindly rapid-fire into the center, you will instantly jam your Conveyor Belt. You must open the center slowly, utilizing the edges only when a matching lower target appears. The lower Boxes dictate everything. Clearing that first Dark Blue target is the only way to shift the board state and reveal the targets you actually need for the keys.

Follow this exact release order to survive the early bottleneck and break the chains. Do not rush the center. Keep your Conveyor Belt clean.

Breaking the Front Line in Marble Sort Level 216

The start is completely scripted by the lower Boxes. You have a Dark Blue and an Orange target waiting on the right side of the bottom area. You need to feed them immediately to cycle the targets.

Tap the Dark Blue box at the very bottom center of the Top Tray. This feeds directly into your waiting Dark Blue lower Box.
Drop the Cyan box sitting right next to it. You do not have a Cyan target yet, but you must move it to access the row behind it. It will sit safely on the Conveyor Belt.
Tap the Orange box that you just uncovered. This will zoom down and fill the waiting Orange bottom Box.
Clearing that Orange lower target will cycle the board. Watch the new lower Boxes slide in. You are looking for a Red target or a Light Pink target.
Grab the Red box on the right side of the Top Tray. This holds the Brown Key. When this clears, the Brown Lock and Key chain on the top left of the board completely shatters.

The Mystery Box Midgame in Marble Sort Level 216

With one lock broken, the board opens up slightly. But the pressure on the Conveyor Belt is about to spike. You will soon see a nasty mix of Yellow, Red, Cyan, and Light Pink marbles flooding your available space.

Now target the Light Pink box on the left side of the Top Tray. This box holds the Purple Key.
Clearing the Light Pink box shatters the Purple Lock and Key chain on the top right. Both sides of the board are now mechanically free.
Start attacking the Arrow Boxes. The down-pointing Light Blue Arrow Box on the left is now safe to release, assuming a Light Blue target has cycled into your bottom area.
Carefully peel back the central Mystery Boxes. Tap exactly one. Look at the color it reveals. If you do not have a matching lower Box, leave it alone. Do not tap a second Mystery Box until the first one is sorted.
Manage the Yellow and Green Arrow Boxes on the edges. Only drop them when their corresponding lower targets are fully visible.

Surviving the Final Panels in Marble Sort Level 216

You still have the two top Panels to deal with. They started with a "2" on them, meaning you needed two valid box clears below them to make them vanish.

By clearing the keys and the front line, the countdown on both Panels will hit zero. They will disappear, revealing the hidden top corners.
The top corners hide heavy, solid colors like Brown and Green. Stop clicking entirely. Look at your Conveyor Belt. It is likely choked with leftover Cyan or Light Pink marbles.
Wait for the bottom area to cycle. Let the loose marbles on your belt sort themselves into the newly spawned targets before you drop the heavy Brown and Green boxes from the top.
Once the belt is mostly empty, drop the top corner boxes to finish off the remaining targets and clear the board.
