Marble Sort Level 100 Walkthrough & Solution

Level 100 Board Overview: The Jagged Wall with Countdown Wings

Level 100 is a milestone stage that refuses to celebrate. The Top Tray is a cramped, jagged six-column block with the top-right corner bitten off, painted in bright Yellow, Purple, Green, Pink, and Light Blue. On the far-left and far-right wings sit blue Panels marked “3” — each one seals an entire column of marbles until you clear three lower Boxes.

The center is worse: a solid mass of grey Mystery Boxes, many of them chained together as Connected Boxes. You are pulling colors blind, and one bad tap into a full belt ends the run.

Now the real insult — the mismatch. The active receiver Boxes want Dark Blue, White, Orange, and Green. The front row of the tray offers Yellow, Purple, Green, and Pink. Exactly one of those four has a home. The other three are bait you are forced to handle, because the Mystery Boxes hiding your Dark Blue and White sit directly behind them.

The Trap in Marble Sort Level 100

This level weaponizes a single ugly choice:

• The forced sacrifice: you cannot reach the hidden center without moving the Yellow and Purple blocks, but moving them means parking two unmatched colors on a Conveyor Belt that is already tight. There is no clean option — only a managed one.
• The Panel countdown: every cleared bottom Box ticks both blue Panels down from 3. Rip them off and the left wing reveals a White cluster while the right wing exposes Purple and Yellow. Until then, you are playing with half a board.
• The diagonal chain: clearing the front lines triggers bottom-tied Connected Boxes — a thick black diagonal line locking a Box in column three to its twin in column four. Fill one early and it just sits there blocking everything behind it while you scramble to fill the other.
• The Pink holdback: the front-row Pink looks like the natural third sacrifice. It is not. You will need that belt room for whatever the Mystery Boxes spit out.

Marble Sort Level 100 Step-by-Step Walkthrough

Surgical order only. No spam-tapping the front row.

Opening: one clear, two sacrifices

1. Tap the Green marbles on the center-right of the front row. They drop into the front-right Green Box — your only free move, and it ticks both Panels down to 2.
2. Tap the Purple block and park it on the Conveyor Belt.
3. Tap the Yellow block and park it too. You are buying visibility with belt space.
4. With the front line shifted, tap a grey Mystery Box in the center. If it reveals White, Orange, or Dark Blue, send it straight to its Box.
5. Leave the Pink block where it is. That belt slot is reserved for surprise colors.

Mid-game: Panels off, chains on

Two more clears and the blue Panels rip away — a White cluster on the left wing, Purple and Yellow on the right. Enjoy it, because the bottom rows immediately throw the diagonal Connected Boxes at you, typically an Orange Box in column three tied to a twin in column four.

6. Feed the connected pair slowly. Never dump marbles into one half of the chain unless your belt can survive the wait while you fill the other. A satisfied-but-stuck Box is just a wall.
7. Drop the White cluster from the opened left wing into the White Box. Fast, clean, and it shifts the bottom stacks forward again.
8. Dig into the Light Blue concentration hiding in the center of the tray behind the first Mystery Boxes. Match it whenever a Light Blue slot opens and hollow out the middle of the board.

Cleanup: the jagged back-right corner

9. Check the top-right corner: a solid block of Red and Dark Blue sits behind where the right Panel used to be. Do not touch it until your belt is nearly empty.
10. The bottom now asks for Pink and Yellow. Spend the Pink you held back from the opening, pair it with the Pink from the center, and blast those columns clear.
11. Send the Red and Dark Blue down last. Verify the Box color before every tap — a misclick here wastes a perfect run.

Level 100 Tips Recap

• Only Green is safe at the start. Everything else in the front row is a calculated sacrifice, not a clear.
• Track the Panel countdown after every Box clear — the third one changes the whole board.
• Never fill one half of a Connected Box pair unless you can afford to let it sit there while you feed the twin.
