Marble Sort Level 109 Walkthrough & Solution
Level 109 Board Overview: The Panel Lockdown and the Green Flood

Level 109 is a discipline check. The board opens with huge, tempting marble clusters and punishes anyone who taps what looks easy. The colors that run this level are Yellow, Purple, Blue, and — later — a whole lot of Green.
The Top Tray leads with four fat nine-marble clusters: Dark Red, Cyan, Light Pink, and Yellow. Above them sits a messy layer of flat single squares, and several of those are Connected Boxes — tap a linked Dark Red square and its Orange partner rides down onto the Conveyor Belt with it. The back row hides four Mystery Boxes, and both outer columns are sealed under Panels stamped with a “3”.
Your starting receiver Boxes ask for Yellow, Purple, Blue, and Yellow. Check the front row against that list: exactly one of those big clusters — the Yellow — has a legal home. Dark Red and Light Pink are sitting there with no Box at all.
The Trap in Marble Sort Level 109
The board is rigged to overflow your belt in two waves:
- The front-row bait: Dark Red and Light Pink are the biggest, easiest taps on screen. Neither matches an active Box. Drop either one and nine dead marbles occupy your belt for most of the level.
- The Connected Boxes in the middle: several Purple and Blue squares you genuinely need are horizontally linked to junk colors like Orange. Every pull can cost you an extra belt slot, so you have to budget for the passenger before you tap.
- The flank Panels: the outer columns only open after three Box clears. Behind them wait heavy Purple and Green stacks on the left, and Pink, Red, and more Green on the right.
- The Green flood: when the Panels break, Green Boxes cycle in — but not fast enough. Dumping a full Green cluster while the bottom only wants a few Greens is how most runs die here.
The four Mystery Boxes in the back row are the endgame. By the time you reach them, belt space is the only thing that matters.
Marble Sort Level 109 Step-by-Step Walkthrough
The opening is all about restraint. Three quick Box clears flip the whole board.
Opening: thread the center channel

- Tap the front Yellow cluster. Two Yellow Boxes are waiting in the active row, so this is your one safe heavy move.
- Leave the Dark Red, Cyan, and Light Pink clusters completely untouched. They are bait, full stop.
- Work through the flat squares in the middle rows and pull the single Purple and Blue pieces the active Boxes are asking for.
- Before each pull, check for horizontal links. If the square you need is chained to a dead color like Orange, make sure the belt has room to park the passenger while the good color slides home.
- Sequence Yellows, Purples, and Blues until you bank three Box clears. The moment the third one lands, both side Panels shatter.
Mid-game: break the Panels, starve the Green
- Read the new active Boxes before touching the flanks. Cyan, Orange, and Green typically rotate in.
- Resist the giant Green clusters the Panels just exposed. A nine-marble dump into a Box that wants three Greens floods the belt instantly.
- Feed Orange and Cyan from the remaining center flat squares first. Let the Green stacks sit on the flanks until multiple Green Boxes are queued at the bottom.
- Circle back to the Dark Red and Light Pink clusters from step 2. Once their Boxes finally cycle into the active row, drop them — they clear in one go without costing a single belt slot.
Cleanup: the Mystery Box reveal
- Flip the four back-row Mystery Boxes. Because you protected your belt space all game, any surprise color they throw at you has somewhere to sit.
- Route whatever the Mystery Boxes revealed into the matching Boxes as they scroll up. Keep taps deliberate and close out the level.

Level 109 Tips Recap
- Big cluster plus no active Box equals bait — Dark Red and Light Pink stay parked until their Boxes appear.
- Count your clears toward the “3” Panels so the flank reveal never catches you mid-jam.
- Treat every Connected Box pull as a two-slot cost, and never dump Green until Green Boxes are stacked at the bottom.
