Marble Sort Level 352 — Walkthrough and Solution

Marble Sort Level 352 presents a cross-shaped Top Tray with a central green x2 gate that doubles any marbles dropped through it. The primary strategy is to tackle the bottom row of marbles immediately, ignoring the tempting higher colors until you've established a clear path and have matching Boxes ready.

The Top Tray holds Black, Purple, and Blue clusters at the bottom row, with White, Dark Red, and Yellow marbles stacked above. Two light blue Tunnels marked with a "3" sit at the top, unreachable until the lower colors are cleared. The lower Boxes are arranged in four lanes: far-left has Blue, Blue, Purple; mid-left has Purple, Purple, Purple; mid-right has Black, Blue, Purple; far-right has Black, Black, Purple.

Marble Sort Level 352 Walkthrough

Your active Boxes at the start are Blue, Purple, Black, and Black from left to right. The queues behind them demand many Purple and Blue marbles early on, so focus on clearing those colors first. The higher Orange, Pink, and White marbles are not needed yet and should be left alone.

The central gate is the main trap: dropping the wrong color through it doubles the count and can quickly fill your Conveyor Belt. You must avoid the middle columns until you have a matching Box available.

How to Beat Marble Sort Level 352 — Step-by-Step

Phase one: Clear the bottom row

1. Tap the Black cluster on the far left of the bottom row to send it down to the active Black Box on the right side.
2. Tap the Purple cluster on the far right of the bottom row to feed the active Purple Box in the mid-left lane.
3. Tap the Blue cluster in the middle of the bottom row to drop it into the active Blue Box on the far-left lane.
4. Tap the remaining Purple cluster, which is second from the left in the bottom row.

Phase two: Bypass the Multiplier Gate

1. Do not tap any marbles directly above the x2 gate unless you have a matching open Box. Avoid the middle columns containing Pink, Dark Red, and White for now.
2. Pull marbles from the outer edges: tap the Blue from the left column to feed the newly exposed Blue Box.
3. If a Dark Red or Black marble appears on the right edge, drop it only when a matching Box is available.
4. Continue feeding Purple marbles from the left column and the middle-left area (not through the gate) to clear the stack of Purple Boxes.
5. When a Pink or Dark Red Box eventually appears, you can safely tap the middle columns. The gate will double the marbles, filling the Box in one drop.

Phase three: Clear the top Tunnels

1. Once the middle section is cleared, the board opens up to solid color blocks and the two top Tunnels.
2. Whenever a Tunnel releases a color, immediately check your bottom Boxes for a match.
3. Keep two Conveyor Belt slots empty to handle unexpected Tunnel outputs. Work on clearing the large blocks on the sides while waiting for the right Boxes.
4. Feed the Tunnel marbles into the remaining Boxes as they cycle forward, and the board will clear.

Tips & tricks

• Always prioritize clearing the bottom row first to expose the Boxes you need.
• Keep an eye on your Conveyor Belt space; avoid filling it with unneeded colors.
• Use the Multiplier Gate strategically when you have a matching Box to fill it quickly.

Common mistakes

• Dropping middle-column marbles through the gate too early, causing your belt to flood.
• Ignoring the Box queue and clearing colors that don't match upcoming demands.
• Failing to leave empty slots on the belt for Tunnel outputs, leading to a jam.
