Marble Sort Level 126 Walkthrough & Solution

Level 126 Board Overview: The Mystery-Stack Middle

Level 126 is a funnel-fed sorting board with one obvious weakness: the middle of the Top Tray is a row of gray mystery boxes. The tray runs five columns wide on a wooden board, and the two end columns are dead space — each one is packed with stacked wooden crates that stay sealed for the entire solve.

The three middle columns are what actually feed the level. Each one caps a stack of mystery boxes with a single visible marble: Light Pink, Green, and Purple sit on top, one per column. Beneath the mystery stacks, at the bottom of each column, sit Yellow, Pink, and White marbles, with a Dark Red at the right edge. A funnel-shaped exit in the center of the tray’s lower edge pulls everything down.

Below the tray, a funnel and a short conveyor track feed a four-wide grid of three-slot receiver Boxes, stacked four rows deep. The level opens with the funnel already preloaded: a wave of Cyan is queued first, with Orange, Yellow, Pink, and Red mixed in behind it. In the first seconds those marbles pour into the mostly-empty Box grid — the opening is a flood, not a trickle.

The Trap in Marble Sort Level 126

• End columns: each side column is stuffed with wooden crates — an X-brace block over a plain plank block. Nothing comes out of them for the whole solve; treat them as walls, not inventory.
• Cap marbles: Light Pink, Green, and Purple sit on top of the three middle columns, pinning the mystery stacks beneath them. Releasing a cap early frees its whole stack at once, and you lose control of the reveal order.
• Mystery stacks: the gray question-mark boxes hide the marbles that keep the level going. They clear one by one, and each reveal feeds the queue whatever color it happens to be — you cannot plan around them.
• Mixed queue: the funnel is never color-pure. Cyan, Orange, Yellow, Pink, Red, Green, Purple, and Blue all ride the track at some point, so releasing a marble whose Box is not open means a wrong-color drop and a stalled column.

Marble Sort Level 126 Step-by-Step Walkthrough

The level is front-loaded. Manage the opening flood and the rest plays like clockwork.

Opening: ride the preloaded wave

1. Let the funnel drain untouched at first — the queued Cyan wave is already aimed at the empty front Boxes.
2. Feed the Orange, Yellow, Pink, and Red marbles that follow the Cyan; their Boxes are already sitting in the grid.
3. Release the bottom-row marbles of the middle columns (Yellow, Pink, White, and the Dark Red at the right) — they sit closest to the tray’s center exit.
4. Leave the cap marbles (Light Pink, Green, Purple) alone until their columns thin out underneath.
5. As the front row of Boxes completes, match the cycling queue — Green, Blue, and Purple Boxes open in the second row.
6. Keep every Box fed to the front: a full Box pops and the grid shifts, which is what exposes the next empty row.

Midgame: crack the mystery stacks

7. Watch the middle columns — as each bottom slot empties, a mystery box drops away and reveals the marble beneath.
8. Release each revealed marble immediately if its color has an open Box; otherwise leave it waiting in the tray.
9. Work one column at a time. Clearing a full mystery stack in order keeps the queue color-predictable.
10. When the Light Pink cap comes free, drop it — Pink Boxes cycle hard through the midgame.
11. Do the same for Green and Purple as their caps release; keep the second and third Box rows fed.
12. The corner crates never open — don’t wait on them and don’t route around them; they’re permanent scenery.

Cleanup: the final wave

By the last minute the tray is nearly empty — only stragglers remain.

13. Sweep the leftover Orange, Dark Green, Purple, Bright Green, and Red stacks into their open Boxes.
14. The last color to fall is Pink. Feed the final Pink marbles and let the last Boxes pop on their own.
15. Once the tray is empty and the grid clears, the level is done — the reward popup lands immediately.

Level 126 Tips Recap

• The funnel starts preloaded — let the Cyan wave drain before you touch the tray.
• The corner crates are sealed walls; every playable marble lives in the three middle columns.
• Crack the mystery stacks one column at a time to keep the reveal order predictable.
• Pink is the closing color — save it, don’t dump it early.
