Marble Sort Level 25 Walkthrough & Solution

Level 25 Board Overview: The Locked Lid and the Red Decoys

Level 25 splits the board in two. The whole upper half of the Top Tray is sealed behind a blue Panel stamped with a countdown of 4, backed by a field of gray Mystery Boxes you cannot touch yet. Everything you do at the start happens in the bottom half, and the colors in play are Lime Green, Orange, Red, and White.

The exposed front row of the Top Tray reads left to right: Lime Green, Red, Red, Lime Green, White, with a solid wall of Orange stacked directly behind them. Down below, the front receiver Boxes are asking for Lime Green, Lime Green, Orange, and White.

Spot the mismatch. Not a single active Box wants Red, yet two big Red blocks sit front and center, begging to be tapped. That pair is the entire trap.

The Trap in Marble Sort Level 25

Every element of this layout pushes you toward one bad move:

• The center Reds: tapping them feels productive because they’re big and exposed. They have nowhere to go. They’ll land on the Conveyor Belt and sit there, clogging the exact slots you need for shuffling Lime Green and Orange around.
• The edge blocks: the far-left Lime Green and far-right White are your real openers. Each one has a Box waiting, and clearing them opens the lane into the Orange wall.
• The Orange wall: only reachable after the edges move. Route it straight into the front-center Orange Box.
• The Panel: it needs exactly four cleared Boxes before it lifts. Until then, the top half doesn’t exist. Don’t plan around colors you can’t see.

The receiver columns are deep, and Red Boxes do exist — they’re just stacked behind everything else. Your job is to survive until they rotate forward, with the belt still functional.

Marble Sort Level 25 Step-by-Step Walkthrough

The opening is rigid. Improvise later, not here.

Opening: work the edges, ignore the middle

1. Tap the far-left Lime Green block. It drops cleanly into a Lime Green Box.
2. Tap the White block on the far right. It clears the White Box and opens the space behind it.
3. Tap the second Lime Green block, the one just right of center. That’s the second Lime Green Box gone.
4. Pull the Orange blocks from the wall into the front-center Orange Box.

That’s four clears. The Reds stay untouched — they’re parked, not forgotten.

Mid-game: the Panel lifts and the board doubles

Four cleared Boxes pop the Panel, and the sealed top half floods into play. Mystery Boxes start flipping: a Light Blue block appears top left, Pink in the middle, and a dense cluster of still-hidden boxes on the top right. At the same time the receiver Boxes shove forward, and now they want Light Blue, Blue, and a pile of Red.

5. Tap the revealed Light Blue cluster on the upper left into the fresh Light Blue Box.
6. Release the two Reds you’ve been saving since the opening. The stacked-up Red Boxes in the middle columns will swallow them fast.
7. Watch for Pink blocks dropping in up top — but hold them until a Pink Box physically rotates into the front row. Pink is the mid-game bait now.

Cleanup: the top-right corner, one pull at a time

8. Clear the Lime Green blocks exposed under where the Light Blue sat.
9. Clear the Blue blocks sitting above the old Red starting position.
10. Work the top-right Mystery Box cluster slowly: pull one block, check what color hit the belt, and only pull the next one if a matching Box is active. No matching Box means stop and let the belt digest.

Level 25 Tips Recap

• A big exposed block with no Box is a trap, not an opportunity — the twin Reds prove it.
• Count your four Panel clears before you start so you know exactly when the board changes.
• In the Mystery Box corner, pull one at a time. Spam-tapping hidden boxes is how belts jam.
