Marble Sort Level 105 Walkthrough & Solution

Level 105 Board Overview: The Alternating Box Chokepoint

Level 105 puts a smile on your face and a knife in your belt. The Top Tray shows big, juicy clumps of Light Blue, Green, and Purple — and not one of them has a home. The colors that actually open this level are Yellow and Brown, and they’re scattered thin across six tall columns.

Your front-row receiver Boxes alternate: Yellow, Brown, Yellow, Brown. Behind them wait Orange, Yellow, Light Pink, Yellow, with a third row of Pink, Orange, White, Pink. Meanwhile the bottom edge of the Top Tray isn’t marbles at all — it’s a shelf of five waiting Boxes (Yellow, Brown, Purple, Brown, Green) holding the stacks up.

Two countdowns watch over everything. A Tunnel on the right wall shows a 3, and a wrapped square in the top center shows a 5. Neither helps you until you’ve earned enough clears.

The Trap in Marble Sort Level 105

The columns are stacked to punish greedy tapping. Here’s what you’re actually looking at:

• Far-left column: Orange over Black. Both are dig costs, not targets.
• Second column: Purple over Green over Light Blue over Green. A pure bait stack — leave it sealed as long as you can.
• Third column (under the wrapped 5): Purple over Yellow over Red. One of your precious Yellows is buried here under a Purple.
• Fourth column: Brown over Black. Your first easy Brown, plus a Black you’ll be parking.
• Fifth column: Light Pink over Orange over Light Blue over Light Pink. Expensive to dig, but the Orange has a future.
• Far-right column: Yellow over Orange over Light Blue. Your opening tap lives here.

The math is brutal: four front Boxes, and only two exposed marbles that match them. To fill the rest you must pull wrong colors onto the Conveyor Belt as temporary cargo. That’s legal — but the belt is short, and if you also crack open the Light Blue/Green stack on the left, you’ll drown in marbles no Box wants.

Marble Sort Level 105 Step-by-Step Walkthrough

The opening sequence is tight. Follow it exactly.

Opening: feed the alternating Yellow-Brown Boxes

1. Tap the Yellow marble on top of the far-right column. Straight into a Yellow Box.
2. Tap the Brown marble on the fourth column. One of each delivered.
3. Tap the Purple marble capping the third column and let it ride the belt. It’s cargo — you’re after what’s underneath.
4. Tap the Yellow you just exposed in the third column into the next Yellow Box.
5. Tap the Light Pink marble on the fifth column onto the belt.
6. Tap the Orange marble beneath it. Park it too.
7. Tap the Orange on the far-left column so it groups with the one from step 6.
8. Dig the Orange out of the far-right column, then feed every Yellow and Brown you’ve uncovered into the front Boxes.

Mid-game: the Tunnel pays out Black

Three clears tick the right-wall Tunnel to zero, and the whole board exhales. The Tunnel fires a solid Black Box straight into your receiver area while the second Box row slides forward — suddenly Black, Orange, and Brown are all wanted.

9. Flush the Black and Orange marbles you’ve been hauling on the belt into their fresh Boxes. The belt goes from packed to empty in seconds.
10. Keep clearing toward five. The moment your fifth Box fills, the wrapped square in the top center shatters and unlocks the middle of the board.

Cleanup: the shelf drops

With the center open, the hard part is over.

11. Clear the Light Pink and Red marbles into the newly rotated Boxes.
12. The shelf Boxes under the Top Tray — Purple, Green, Light Blue — drop into the receiver area. That second-column stack finally has somewhere to go.
13. Pull the Light Blue and Green marbles down methodically, then finish the leftover Purple. Never tap a deep-layer color before its Box is visible.

Level 105 Tips Recap

• Yellow and Brown are the only colors that matter at the start — every other early tap is parking, not progress.
• The Tunnel’s Black Box is your relief valve; plan to be holding Black and Orange when the third clear lands.
• Touch the second-column Light Blue/Green stack only after the shelf Boxes drop.
