Marble Sort Level 474 — Walkthrough and Solution

This puzzle is a color-sorting test where careful sequencing beats speed. The key is to first satisfy the Green demand, then manage the Orange pair without touching the bottom-center trap marbles until matching boxes appear.

Marble Sort Level 474 presents a dense upper grid that narrows into a T-shaped protrusion at the bottom center, featuring two textured Yellow marbles and one textured White marble. Along the top edge sit three Blue archways labeled with numbers 2, 3, and 2 from left to right. On the left side, a Cyan and a Brown marble are connected together, while on the right, a 2x2 group of Blue, Red, Yellow, and Purple rests inside a dashed border.

The starting bottom boxes require, from left to right: Orange, Orange, Green, and Red. This lineup forces a disciplined opening.

The central trap is the exposed Yellow and White marbles at the bottom center of the top tray. Tapping them early fills the conveyor with unused colors, severely limiting flexibility when digging for Orange.

How to Beat Marble Sort Level 474 — Step-by-Step

Phase one: Secure the Green box

1. Locate the accessible Green marbles in the lower-middle rows, just above the bottom T-shape.
2. Tap each Green marble to send it down, filling the Green box completely.
3. Wait for the belt to clear the Green pieces before moving on.

Phase two: Manage the Orange pair

1. After the Green box clears, a new box slides in. Now focus on the two Orange boxes.
2. Find the exposed Orange marble on the far left edge and tap it.
3. Find the exposed Orange marble on the far right edge and tap it.
4. Peel away the Red and Blue marbles sitting above the remaining Orange pieces, routing any Red marbles into the starting Red box immediately.
5. Clear at least one Orange box before making any aggressive moves toward the center.

Phase three: Open the side mechanics and tunnels

1. When a Yellow or White box appears at the bottom, drop the textured marbles from the bottom center to open the core.
2. For the connected Cyan and Brown marbles on the left, tap them only when at least two conveyor slots are empty, ideally when a Cyan or Brown box is active.
3. Break open the dashed 2x2 square on the right when at least two of its colors (Blue, Red, Yellow, Purple) have matching active boxes.
4. Work up the central columns, clearing the path beneath the three top archways without jamming the belt.
5. When the tunnels activate, release their hidden marbles slowly. Prioritize the middle tunnel (holds 3 marbles) by clearing blocking colors first.
6. Match newly revealed tunnel colors to active bottom boxes, leaving any unmatched marbles in place.
7. Keep at least three conveyor slots open and cycle through the final boxes to finish.

Tips & tricks

• Always count your conveyor slots before tapping any connected or dashed group to avoid belt overflow.
• Use the starting Red box as a temporary sink for Red marbles you uncover while digging for Orange.
• When the tunnels release multiple colors, pause and check which bottom boxes are active before each tap.

Common mistakes

• Dropping the bottom-center Yellow and White marbles early, which clogs the belt and blocks progress.
• Breaking the dashed square too soon, causing Blue, Red, Yellow, and Purple to pile up without matching boxes.
• Tapping the connected Cyan and Brown pair when only one slot is free, forcing an unwanted drop.
