Marble Sort Level 693 — Walkthrough and Solution

Marble Sort Level 693 presents a puzzle where the top tray is a pyramid of boxes, with two Blue Tunnels in the middle, each holding four hidden balls. The visible colors are Black, Red, Blue, and Light Green, but many are concealed behind Mystery Boxes. The bottom row initially demands Black and Red, so you must clear those first to avoid jamming the conveyor.

The top tray's front row from left to right: Black, Black, Red, Light Green, Blue. Behind the first Black is a Blue; behind the second Black is a Mystery Box. The Blue Tunnels are central and marked with a '4', meaning they will release four balls each once the space in front is cleared. The bottom stacks are four columns wide, starting with Black, Black, Red, Red on top, with Light Green, Pink, Orange, and Blue underneath, some secured by locks.

Marble Sort Level 693 Walkthrough

The initial bottom boxes require Black and Red. You have two Black and two Red available in the top tray's front row, but one Red is blocked behind a Blue. The right side has Light Green and Blue, which are tempting but should be avoided early because there are no matching bottom boxes yet.

The main trap is the Light Green and Blue boxes on the right front. If you tap them early, they'll sit on the conveyor belt, filling space and limiting your ability to handle the Blue Tunnels' output. The key is to wait until the bottom row exposes those colors.

How to Beat Marble Sort Level 693 — Step-by-Step

Phase one: Clear the starting row

1. Tap the first Black box on the front left, then the second Black box next to it. These drop into the two Black bottom boxes, clearing them.
2. Tap the front Red box in the middle. It falls into one of the Red bottom boxes, clearing it.
3. Now tap the front Blue box on the right. It will sit on the conveyor belt temporarily, but this is necessary to expose the Red box behind it.
4. Tap the newly exposed Red box. This clears the final Red bottom box in the starting row.

Phase two: Manage the tunnels and mystery boxes

1. With the starting row cleared, the bottom row now shows Light Green, Blue, and Pink targets. Tap the Light Green box on the front right to clear it into the Light Green bottom box.
2. The Blue Tunnels activate once the space in front is clear. They will start dispensing Blue balls. Use these to clear the Blue bottom boxes as they appear.
3. Now tap the front-most Mystery Box. Watch the color that comes out. If it's Orange or Brown, stop and wait until you expose an Orange or Brown bottom box later. Do not tap multiple Mystery Boxes in a row, or you'll overwhelm the conveyor.

Phase three: Unlock the final locks and finish

1. Look for the Lock and Key boxes. There is a Pink key on the far left edge and a dark Green key on the right. Tap the Pink key as soon as a Pink bottom box is available.
2. Clear the keys to unlock the bottom rows, giving you more places to put balls. Without these, the conveyor will jam.
3. Focus on emptying the two central Blue Tunnels. Once they hit zero, the top section unlocks, revealing final grey key boxes.
4. Match the remaining balls from the back corners into the unlocked bottom boxes. Take your time to avoid a final jam.

Tips & tricks

• Always prioritize clearing the bottom row demands before tapping any non-matching color.
• When a Mystery Box drops an unwanted color, stop tapping and wait for the bottom to cycle.
• Keep the conveyor belt as empty as possible, especially before the Blue Tunnels activate.

Common mistakes

• Tapping the Light Green or Blue front boxes too early, which floods the conveyor.
• Rapidly tapping Mystery Boxes without waiting for matching bottom boxes.
• Ignoring the Lock and Key boxes, which prevents unlocking lower rows.
