Marble Sort Level 574 Guide: The Cross-Lock Key Trap

You load into the game and immediately see heavy chains blocking half your screen. Marble Sort Level 574 is entirely about sequence. If you try to play this like a standard color-matching puzzle, the board will choke you out before you even reach the midgame.

The dominant colors pushing you around here are Light Green, Pink, and Dark Red. The Top Tray is split into columns, heavily restricted by a brutal double Lock and Key setup. You have a massive cluster of Mystery Boxes crowding the lower half of your screen. You cannot see what colors you will need next. Everything relies on forcing the correct key to drop at the exact right moment to keep the Conveyor Belt clear.

The Cross-Lock Board Pattern in Marble Sort Level 574

The layout of Marble Sort Level 574 is designed to bait you into a quick loss. Let’s look at exactly how this board is stacked so you know what is coming.

Your starting bottom Boxes are Light Green on the far left, two Dark Reds in the center, and Pink on the far right. Underneath this top layer is an intimidating wall of grey Mystery Boxes. You have no idea what colors they want until the top layer clears.

Up in the Top Tray, the front line gives you four bundles: Purple, Light Green, Pink, and another Light Green. Right above that front line, things get messy. On the left, you have Connected Boxes tying a Dark Red bundle to a Cyan bundle.

The real nightmare is the chain placement. A purple lock chains down the entire top-left section. An orange lock chains down the middle of the rightmost column.

Here is the exact trap. The purple key is at the very top of the rightmost column. You cannot reach it. The orange key is sitting right in the middle of the board, resting on a green tile. To win Marble Sort Level 574, you have to execute a cross-board rescue mission. You must dig out the center to reach the orange key. That orange key unlocks the right side. You then push up the right side to grab the purple key. That purple key finally frees the heavy top-left section, which hides several Gift Boxes marked with 4s and a 2.

Drop the wrong front-row bundle, and your Conveyor Belt fills up with useless marbles while you desperately wait for a matching Box to reveal itself from the mystery stack.

Follow this exact tap order. Do not try to rush ahead. The lower Mystery Boxes dictate your pacing, so you must clear the front lines perfectly to force good reveals.

Dodging the Purple Bait in Marble Sort Level 574

Your first few moves dictate whether you survive the opening. The left side is a trap.

1. Tap the Light Green bundle in the front row. It drops straight into the matching bottom Box on the left.
2. Tap the Pink bundle in the front row. It clears the Pink Box on the far right.
3. Leave the front-left Purple bundle alone. This is pure bait. There is no active Purple Box right now. If you drop it, those marbles will sit on your Conveyor Belt and steal your breathing room.
4. With the outer bottom Boxes cleared, two new targets will flip up from the Mystery Box grid. Use these new targets to start stripping away the middle columns. You want to expose the White and Cyan bundles sitting right in front of the orange key.

Breaking the Orange Chain in Marble Sort Level 574

Once you crack the first layer of mystery tiles, your entire focus shifts to the center of the board.

5. Keep clearing the middle tiles as their matching lower Boxes reveal themselves. You will likely pull the Cyan, Pink, and White bundles next.
6. The moment the path is clear, tap the orange key. It will drop and shatter the chain blocking the right side of the Top Tray.
7. Look at the newly opened right column. Your next goal is the purple key sitting at the very top.
8. Watch your Conveyor Belt. Only tap the tiles in that right column if you have the matching bottom Boxes ready. Do not flood the belt just to rush the key. Methodically clear the White and Orange bundles in that right-side column.

Releasing the Gift Boxes in Marble Sort Level 574

The endgame triggers the moment you secure the final key. The board state completely flips from tight and restricted to wide open.

9. Tap the purple key. The massive chain on the top-left explodes, freeing the rest of the board.
10. You now have access to the Connected Boxes at the top left (Purple and Green). Drop them when the belt is clear.
11. You also unlocked the blue and purple Gift Boxes. Pay attention to the numbers on them (4 and 2). When the nearby boxes drop down, these will pop open and flood the board with new colored boxes.
12. Prioritize clearing the remaining Mystery Boxes on the bottom. Now that the top is unlocked, you have a massive pool of colors available. Match whatever the bottom row demands and finish the level.
