Marble Sort Level 574 — Walkthrough and Solution

The puzzle is a cross-lock layout where two keys interlock and block access to each other's locks. To win, you must free the Orange key on the lower-left, use it to unlock the right side, then climb to the Purple key above. Marble Sort Level 574 demands strict sequence discipline—wrong early taps clog your belt.

The board starts with three open bottom Boxes: Light Green on the far left, two Dark Reds in the middle column, and Pink on the far right. Above them, a wall of grey Mystery Boxes hides the rest. In the Top Tray, four front bundles sit ready: Purple, Light Green, Pink, and another Light Green. Behind them, a connected pair ties a Dark Red bundle to a Cyan bundle on the left. Two locks dominate: a Purple lock chains the top-left section, and an Orange lock pins the rightmost column's middle. The Purple key rests at the very top of that right column; the Orange key sits mid-board on a green tile. Several Gift Boxes marked with numbers 4 and 2 hide under the top-left chains.

Marble Sort Level 574 Walkthrough

Your opening demands are Light Green (left), Dark Red (center), Pink (right). The front-left Purple bundle is a decoy—no Purple Box is active yet, so dropping it fills your belt with useless marbles.

The core imbalance: the Orange key blocks the path to the Purple key, but reaching the Orange key requires clearing Mystery Boxes that only reveal after you match certain front colors. You must carefully clear the outer boxes to expose the needed tiles.

How to Beat Marble Sort Level 574 — Step-by-Step

Phase one: Clear the outer edges

1. Tap the Light Green bundle in the front row; it falls into the left Light Green Box.
2. Tap the Pink bundle in the front row; it fills the right Pink Box.
3. Leave the Purple bundle untouched for now.
4. As new Mystery Boxes flip up, target the ones matching your now-empty bottom slots—likely White and Cyan bundles that sit near the Orange key.

Phase two: Break the Orange lock

1. Clear more middle tiles as their matching bottom boxes appear, pulling Cyan, Pink, and White bundles.
2. Once the path opens, tap the Orange key; it drops and shatters the chain on the right column.
3. Now focus on the right column: clear the White and Orange bundles there, but only when you have matching bottom boxes ready to avoid belt overflow.
4. Work upward methodically toward the Purple key at the top.

Phase three: Release the gifts

1. Tap the Purple key to explode the top-left chain, freeing the connected Purple-Green bundle and the Gift Boxes.
2. Drop the connected bundle when the belt is clear.
3. The Gift Boxes (marked 4 and 2) will pop open as nearby boxes drop, introducing new colors—match them with the remaining Mystery Boxes on the bottom.
4. Clear the rest of the board by matching whatever colors appear, finishing the level.

Tips & tricks

• Keep your Conveyor Belt as empty as possible; never tap a tile unless its matching bottom Box is open.
• Prioritize revealing Mystery Boxes that sit near the Orange key—they are the critical path.
• When the Gift Boxes open, expect a flood of new colors; handle them one at a time to avoid chaos.

Common mistakes

• Tapping the front Purple bundle early jams your belt and delays your progress.
• Rushing the right column without matching bottom boxes leads to belt overflow and a dead board.
• Ignoring the numbers on Gift Boxes can surprise you with extra colors you're not ready for.
