Marble Sort Level 618 Guide: The Lock and Key Trap

This board is a masterclass in bait. You are staring down a heavy Lock and Key setup that completely paralyzes the upper board. The dominant colors you need to worry about early on are Light Blue, Yellow, Blue, and Purple.

The Top Tray is heavily segmented. A massive iron chain locks down the entire top row, holding pink, blue, green, brown, and orange marbles hostage. The golden key is stranded right in the upper middle. It sits directly on a light blue box, but it is heavily guarded. You have Mystery Boxes surrounding the core, and a nasty sequence of Arrow Boxes dictating exactly what you can and cannot touch.

Down below, you have four distinct columns of bottom Boxes. The active front line demands Light Blue, Yellow, Blue, and Purple. If you try to force anything else, you will fail. The entire level revolves around surviving the lower board long enough to break that top chain.

The Restricted Grid Pattern in Marble Sort Level 618

Let us look at exactly how this board is rigged to fail. You have a grid that forces you to play from the outside edges inward, but the colors you actually need are buried in the center.

The bottom row of the Top Tray is highly specific. On the far left, you have an outward-pointing pink Arrow Box and an orange Arrow Box. On the far right, you have yellow and light blue Arrow Boxes pointing left. Above this bottom rim sits a thick, frustrating layer of grey Mystery Boxes.

The top row is completely dead until you unlock it. That is your biggest roadblock. The real puzzle is routing your way to the key. But the key is sitting on a light blue box, flanked tightly by a yellow right-pointing arrow and a purple left-pointing arrow. You cannot just grab it. You have to dismantle the entire mid-section first.

Watch out for the pink and orange boxes on the bottom left. They look incredibly tempting to tap right away. They are pure bait. Look at your bottom Boxes. Your starting slots need Light Blue (column 1), Yellow (column 2), Blue (column 3), and Purple (column 4). If you hit those pink and orange side arrows too early, those marbles will sit on your Conveyor Belt forever. Your belt will clog. The game will end.

Clearing the front line of bottom Boxes changes everything. Dropping those initial light blue and yellow boxes unlocks the middle layers of the Top Tray, forcing you to instantly react to whatever the Mystery Boxes spit out.

Marble Sort Level 618 Step-by-Step Walkthrough

You need a strict order of operations here. One wrong tap on an Arrow Box will flood the belt. Keep your eyes on the bottom row.

Breaking the Front Line in Marble Sort Level 618

We need to clear operating space immediately. The bottom Boxes dictate your opening moves entirely.

1. Check your bottom Boxes. Your active targets are Light Blue, Yellow, Blue, and Purple.
2. Scan the lower half of the Top Tray for these exact colors. Ignore the pink and orange Arrow Boxes on the bottom left. Leave them alone.
3. Tap the accessible light blue and yellow boxes from the bottom rim of the Top Tray.
4. Target the outer solid purple box on the far left and the solid green box on the far right only when their matching bottom Box moves up to the active slot.
5. Manage your Conveyor Belt space with intense care. Only drop a box if you know it will instantly slot into a bottom Box. Do not park marbles on the belt hoping a matching box will appear soon.

Chasing the Key in Marble Sort Level 618

Now the board gets messy. You cleared the bottom edge of the tray. The grey Mystery Boxes are starting to expose their hidden colors.

1. Shift your entire focus to the golden key in the upper middle.
2. Clear the Arrow Boxes pointing directly at it. This means you must clear the yellow and purple arrows flanking the key box.
3. Match the newly revealed colors from the central Mystery Boxes with the second layer of bottom Boxes. These bottom columns will rotate to demand greens, pinks, and oranges next.
4. Drop the light blue box holding the golden key once the path is clear.
5. Watch the Lock and Key chain shatter. This instantly brings the top row of the Top Tray into active play.

Surviving the Mid-Game Jam in Marble Sort Level 618

This is where the pressure spikes. Once the chain breaks, the Conveyor Belt usually becomes a crowded parking lot for stray pink, blue, and green marbles.

1. Look at your newly rotated bottom Boxes. They will now demand Brown, Orange, and Yellow on the front lines.
2. Release the newly freed brown and orange boxes from the top row. Use them to clear those fresh bottom Boxes immediately before the belt overflows.
3. Attack the vertical stack of dimpled boxes that settles on the left side of the Top Tray. You must clear this stack of Yellow, Light Blue, and Purple in strict top-to-bottom order.
4. If a green box is blocking an orange box you desperately need, only tap the green if you have at least three totally empty slots on your Conveyor Belt.
5. Clean up the right side. The remaining green and brown boxes at the top will slide down. Match them to the final bottom Boxes to finish the board.
