Marble Sort Level 427 — Walkthrough and Solution

Marble Sort Level 427 presents a two-part board where the left half hides its contents behind a grid of covered squares, while the right half holds a tall stack next to numbered holes. The winning approach is to clear the visible front row first, then force the right stack to descend, which unlocks the hidden left side and the numbered holes.

The left side of the top area shows a large block of covered squares. Underneath them, from left to right, sit a Pink box, a Dark Red box, and a Light Green box. The right side of the top area has a vertical arrangement of solid and striped boxes, with a Purple and a Brown box at its base. The lower front row of the bottom area requires, in order, Brown, Brown, Red, and Green.

Marble Sort Level 427 Walkthrough

The front row of the bottom area asks for two Browns, one Red, and one Green. Only one Brown is visible on the right side of the top area; the second Brown is hidden under the covered squares or inside a numbered hole. The striped boxes on the right, which show Light Blue, Red, Yellow, and Pink stripes, are a decoy; if you pull them early, they will fill the conveyor with unmatched colors.

The main imbalance is that the right side has a single visible Brown, but the front row needs two. The second Brown is locked away, so you must first clear the visible front row to trigger the right stack to drop and expose the hidden Brown.

How to Beat Marble Sort Level 427 — Step-by-Step

Phase one: Clear the Front Row

1. Tap the Dark Red box on the bottom left of the top area. This clears the front Red lower Box and reveals a Light Pink box behind it.
2. Tap the Light Green box on the bottom left. This clears the front Green lower Box and exposes a Purple box behind it.
3. Tap the Brown box on the bottom right of the top area. This partially fills one of the front Brown lower Boxes, leaving a jam on the conveyor.
4. Tap the bottom-right Purple box. This routes into the newly exposed Purple lower Box.
5. Pulling that Purple box causes the entire right-side stack to drop one level, ticking down the counters on the numbered holes next to it.

Phase two: Reveal the Left Side

1. As the right stack drops, the covered squares on the left flip over, showing a vertical column of Pink boxes and a solid Blue box in the middle lane.
2. Yellow and Purple solid blocks also appear at the top left, but do not tap them yet.
3. The new front row of bottom Boxes now shows Orange, White, Light Blue, and Light Pink.
4. Keep dropping the right-side vertical column. Every time you clear a box next to the numbered holes, their numbers decrease.
5. Get the bottom hole from a '4' down to a '0'. When it hits zero, it releases a new set of boxes that often contains the missing colors needed for the midgame.
6. Be cautious with the striped boxes on the right; only tap them when you have at least two empty bottom Boxes ready to catch their mixed output.

Phase three: Clear the Final Chute

1. Prioritize the solid Pink and Light Blue boxes that were hidden under the covered squares.
2. Match them into the deep lower Boxes on the left columns.
3. Continue peeling the right side to open the second and third numbered holes.
4. Never leave more than three unmatched marbles on the conveyor during this stretch. Let the lower Boxes fully clear their three-marble requirement before pulling the next top color.

Tips & tricks

• Always clear the front row first; it triggers the right stack to drop.
• Watch the numbered holes on the right; they count down as you clear boxes next to them.
• Keep the conveyor clear; never pull a striped box unless you have empty spots ready.
• Use the revealed left side to match colors into the deep lower Boxes.

Common mistakes

• Tapping the striped boxes too early floods the conveyor with unmatched colors.
• Ignoring the front row and trying to clear the right stack first locks the board.
• Failing to manage conveyor space during the final stretch causes a jam.
