Marble Sort Level 555 — Walkthrough and Solution

Marble Sort Level 555 is a puzzle where you must clear marbles from a top tray and drop them into matching boxes below, but the board is designed to stall you if you grab colors carelessly. The key is to clear the visible outer colors first, avoid the tempting Purple block, and only then deal with the hidden Mystery Boxes.

The top tray is shaped like a cross. Along its bottom edge, Green is on the left, Purple sits at the center, and Red is on the right. On the left side of the tray, Pink, Yellow, and Orange are locked behind countdown blockers that each need two clears. Slightly right of center, another blocker holding a Red block requires three clears. The lower area has four columns of boxes. The front row shows Light Blue, Red, Red, and Green from left to right. However, the second and third rows of the two middle columns are entirely Mystery Boxes, hiding their required colors until you clear the front row.

In the starting lineup, the boxes demand Light Blue, Red, Red, and Green in the front row. These are the only colors you can safely drop initially because the Mystery Boxes hide the later needs.

The biggest trap is the Purple block at the bottom center of the top tray. Since there is no Purple box at the start, dropping it would fill a conveyor slot uselessly. So, leave it untouched until a Purple box appears.

How to Beat Marble Sort Level 555 — Step-by-Step

Phase one: Clear the front row

1. Tap the bottom-right Red block on the top tray to send it to the Red box in the middle column.
2. Tap the bottom-left Green block to deliver it to the Green box on the far right.
3. With the Green block gone, a Light Blue block is exposed below it; tap it to start filling the far-left Light Blue box.
4. Finish off the front row by matching the remaining Red and Light Blue blocks to their boxes. This will trigger the countdown blockers on the left and center to start decreasing, and the front layer of Mystery Boxes will flip over to reveal their hidden colors.

Phase two: Handle the reveals

1. Read the newly revealed colors in the middle columns; they often include Brown, Purple, or Yellow. If a Purple box appears, you can now drop the bottom-center Purple block.
2. As the countdown blockers reach zero, the left side (Pink, Yellow, Orange) and the middle-right Red block become available. Do not tap them unless their colors appear in the boxes below.
3. Clear the exposed Brown and Light Blue blocks in the middle of the top tray, matching them to the newly revealed boxes.

Phase three: Manage the late game

1. Keep feeding the outer columns (far left and far right) as they cycle through Green, Purple, and Yellow.
2. Always leave at least two empty slots on your conveyor belt. You may need to drop a mismatched color temporarily to reach a critical Green or Orange marble underneath.
3. Once the last Mystery Box is gone, simply match the remaining top blocks to the single box that drops down. Stay patient and methodical to finish.

Tips & tricks

• Focus on clearing the front row completely before touching any Mystery Boxes.
• Keep an eye on the countdown blockers; they open when you clear boxes, but don't grab those colors prematurely.
• Maintain a clean conveyor belt by always matching colors as soon as possible.

Common mistakes

• Dropping the bottom-center Purple too early, which jams your belt.
• Grabbing the newly unlocked side colors before their boxes appear.
• Filling every conveyor slot, leaving no room to maneuver when a tricky sequence appears.
