Marble Sort Level 618 — Walkthrough and Solution

Marble Sort Level 618 presents a Lock and Key layout where the top tray is chained until you release the key. The key sits on a Light Blue box in the upper middle, flanked by a Yellow right-pointing arrow and a Purple left-pointing arrow. The top row holds Pink, Blue, Green, Brown, and Orange marbles, but it stays locked until the key is freed. The lower tray has four bottom Boxes that demand Light Blue, Yellow, Blue, and Purple in order from left to right. You must feed those four colors from the accessible parts of the top tray first, ignoring the tempting Pink and Orange arrows on the bottom left.

The bottom rim of the top tray has outward arrows on the far left (Pink and Orange) and inward arrows on the far right (Yellow and Light Blue). Above that rim sits a layer of grey Mystery Boxes. The center of the tray hides the key, but it is guarded by Arrow Boxes. The key's Light Blue box is surrounded by a Yellow arrow pointing right and a Purple arrow pointing left. You cannot touch the key until you dismantle the mid-section. The bottom Boxes rotate only after you clear the initial Light Blue, Yellow, Blue, and Purple demands. If you tap the Pink or Orange arrows early, those marbles will sit on the Conveyor Belt with no matching bottom Box, jamming the belt and ending the run.

Marble Sort Level 618 Walkthrough

Your opening moves must match the bottom Boxes exactly. The leftmost bottom Box wants Light Blue, the second wants Yellow, the third wants Blue, and the fourth wants Purple. Scan the lower half of the top tray for those colors and tap only those boxes. Ignore the Pink and Orange arrows on the bottom left—they are decoys. Also ignore any Green or Brown boxes until their bottom Boxes appear later.

The core imbalance is that the bottom Boxes demand colors that are buried behind arrows. The Light Blue key box is the only easy early Light Blue, but it is blocked by the Yellow and Purple arrows. You must clear the arrows that point toward the key, which means you have to feed Yellow and Purple to the bottom Boxes first. Those colors are available on the right side and in the Mystery Boxes. Do not try to force Pink or Orange early; they will clog the belt.

How to Beat Marble Sort Level 618 — Step-by-Step

Phase one: Clear the front row

1. Tap the accessible Light Blue box on the bottom rim of the top tray; it might be the one under the key or another on the right side. Feed it to the leftmost bottom Box.
2. Tap the accessible Yellow box on the right side (the arrow pointing left). Route it to the second bottom Box.
3. Tap the solid Purple box on the far left of the lower top tray. Deliver it to the fourth bottom Box.
4. Tap the solid Blue box on the far right of the lower top tray. Guide it to the third bottom Box.
5. After those four clear, the bottom Boxes rotate to demand new colors. Do not touch the Pink or Orange arrows yet.

Phase two: Unlock the key

1. Now the bottom Boxes demand Green, Pink, and Orange. Look for those colors in the Mystery Boxes that have been revealed.
2. Clear the Yellow arrow pointing right that flanks the key. Feed its Yellow to the bottom Box that now wants Yellow (if it does), or park it temporarily only if you have space.
3. Clear the Purple arrow pointing left in the same way, matching it to a bottom slot.
4. Tap the Light Blue box that holds the golden key. Once the path is clear, release it into the bottom Box that wants Light Blue.
5. The Lock and Key chain shatters, bringing the top row into play.

Phase three: Clean up the top row

1. After the chain breaks, the bottom Boxes now want Brown, Orange, and Yellow. Release the Brown and Orange boxes from the top row immediately.
2. Attack the vertical stack of dimpled boxes on the left side. Clear them top-to-bottom: Yellow, then Light Blue, then Purple.
3. If a Green box blocks an Orange box you need, only tap the Green if you have at least three empty slots on the Conveyor Belt.
4. Finish the right side by matching the remaining Green and Brown boxes to the final bottom Boxes.

Tips & tricks

• Always check the bottom Boxes before tapping anything; they dictate the only safe colors.
• Keep the Conveyor Belt empty as much as possible. Never drop a marble unless it can immediately slot into a bottom Box.
• Use the Mystery Boxes to your advantage: they often reveal the exact color you need next, so clear them in a controlled order.

Common mistakes

• Tapping the Pink or Orange arrows early floods the belt with unneeded colors.
• Ignoring the Yellow and Purple arrows that guard the key; you must clear them before the key is accessible.
• Releasing top-row marbles too early, before the bottom Boxes rotate to accept them.
