Marble Sort Level 204 — Walkthrough and Solution

Marble Sort Level 204 presents a split board where the left two columns are sealed behind four horizontal golden pins, trapping Orange, Red, and Green marbles. The right side holds the keys to unlock them. You must focus exclusively on the right half at the start, using only the bottom Boxes as your guide, to release the rings and free the left side.

The layout is asymmetrical, with the Top Tray showing two frozen columns on the left, a third column containing the golden rings (keys), and the right side holding accessible marbles. The bottom Boxes initially demand Light Blue, Pink, Purple, and Light Green. The bottom-most accessible row of the Top Tray consists of Yellow, White, Dark Blue, and Light Green. Only Light Green matches an immediate Box, making it the sole safe opening; the others are decoys that will clog your Conveyor Belt if tapped carelessly.

Marble Sort Level 204 Walkthrough

The front row of the active Boxes, from left to right, requires Light Blue, Pink, Purple, and Light Green. Your opening moves must prioritize Light Green to start clearing the bottom-right corner, then carefully park White and Dark Blue marbles on the belt to expose deeper layers.

The primary trap is that Yellow, White, and Dark Blue marbles appear as easy taps, but they will fill your limited belt space and block access to the Purple and Light Blue needed to progress. Only by threading through the right side in a precise order can you drop the golden rings and unlock the left side without overflowing.

How to Beat Marble Sort Level 204 — Step-by-Step

Phase one: Right-side setup

1. Tap the Light Green marble from the bottom right of the Top Tray and slide it into the far-right Light Green Box.
2. Drop the exposed White marble (from that same column) and the White marble in the second column from the right onto the Conveyor Belt to park them.
3. Route the bottom Dark Blue marble to the belt, increasing the parked count but clearing the path.
4. Now that the lower right is empty, guide the Purple marbles into the third active Box and the Light Blue into the far-left active Box.
5. Continue digging down the third column to expose and clear the Pink marbles into the second Box. This action releases the golden rings, retracting the pins.

Phase two: Lock release and belt management

1. Watch the left columns collapse as the pins retract, revealing clusters of Orange, Red, and Light Green.
2. Identify the new Box cycle: Dark Blue, Pink, Red, and Purple appear in the front row.
3. Before touching the left side, clear the parked Dark Blue and White marbles from your belt into the newly available Boxes.
4. As you dig into the left columns, notice numbered blocks beneath the marbles that control further drops; avoid blind-firing Orange and Red, only sending them when their matching Box is active.

Phase three: Closing out

1. With the belt clear and the left side open, prioritize clearing the Red and Yellow Boxes that cycle in next.
2. Clear horizontal rows evenly across the Top Tray rather than drilling down one column to keep options open and prevent a late-game jam.
3. Keep matching patiently as Boxes rotate, and the board will clear without needing boosters.

Tips & tricks

• Always check the bottom Boxes first to see which colors are safe to drop; never tap a marble just because it's visible.
• Park decoy marbles on the belt only when necessary, and clear them as soon as a matching Box appears.
• When the locks release, take a moment to clear your belt before engaging with the left side to avoid a cascade of unusable colors.

Common mistakes

• Tapping Yellow, White, or Dark Blue early thinking they are helpful—these are bait that will clog your belt.
• Ignoring the bottom Box rotation and tapping left-side marbles out of order, causing a backlog.
• Drilling down one column instead of clearing horizontally, leading to a shortage of usable colors late in the level.
