Marble Sort Level 4 Walkthrough & Solution

Level 4 Board Overview: The Right-Side-Only Puzzle

Four colors here — Orange, Green, Blue, and Yellow — arranged in a Top Tray shaped like a staircase. The two left columns stand four blocks tall; the two right columns are only two high. Most of your marbles are buried on the left, and you can’t touch any of them yet.

The bottom row of the tray reads Green, Yellow, Orange, Orange from left to right. Those two Orange clusters on the right are your only legal opening, because the front row of receiver Boxes wants Orange, Orange, Blue, Orange.

Read that again: three of the four active Boxes demand Orange, and every Orange block lives on the short right side. The board is practically pointing at the answer — and at the bait.

The Trap in Marble Sort Level 4

The left side of the tray is a loaded gun pointed at your Conveyor Belt.

• Bottom-left Green: front and center, completely tappable, and there is no Green Box anywhere in the active row. Tap it and it just camps on the belt.
• Bottom-row Yellow in column two: same problem, worse — its Box is buried at the very back of column four, the deepest grave on the board.
• Right-side stacks: Orange over Blue in column three, Orange over Green in column four. Short, exposed, and they match the front Boxes almost perfectly.

So the level reads right to left, not left to right. Empty the short stacks, feed the Orange wall and the one Blue Box, and let the board shift until the left side’s colors finally have somewhere to land.

Marble Sort Level 4 Step-by-Step Walkthrough

The first four moves decide everything. Get them right and the rest is a downhill dig.

Opening: drain the right side

1. Tap both bottom-row Orange clusters in columns three and four. They pour straight into the Orange Boxes and crack the front wall.
2. Keep your hands off the left Green and Yellow. They’re bait, and the belt has no room for passengers.
3. The right stacks now expose a Blue block in column three. Tap it — there’s a Blue Box sitting in the third receiver slot waiting for exactly this.
4. The first Box layer clears and the board slides forward.

Mid-game: the left side wakes up

5. The new front row wants Green and Blue. Now — and only now — tap the bottom-left Green cluster you’ve been ignoring since move one.
6. Tap the Green block exposed in column four to finish off the remaining Green Boxes.
7. That Yellow cluster in column two? Still not time. Its Box is stuck behind Orange and Green in column four. Wait for it.

Cleanup: topple the tall stacks

8. Once a Yellow Box finally cycles to the front, blast the column-two Yellow cluster.
9. That drops the two Orange blocks and the Blue block stacked above it. Feed each one into its matching Box as it appears.
10. Keep the belt near empty for these last taps — only release a block when its Box is visibly active — and the left columns collapse into a win.

Level 4 Tips Recap

• Read the board from the Boxes backward: three Orange requests means Orange is your only real opening.
• Tappable doesn’t mean playable — the left columns are bait until their Boxes cycle in.
• The deepest-buried Box color (Yellow here) is always your last move, never your first.
