Marble Sort Level 46 Walkthrough & Solution

Level 46 Board Overview: The Center Tunnel Lockdown

Level 46 walls you in with a dense six-column Top Tray and two blue Tunnels parked dead center over columns 3 and 4. Those pipes hold back key marbles until you pull three blocks from beneath each one, and everything you want early is buried under something you do not.

The opening palette is aggressive: Orange, Pink, Purple, Green, and Black all at once. The bottom receivers stack four deep, with Pink, Purple, Orange, and Green showing up front. The real headache hides behind them — Mystery Boxes sit in the back rows, and you will not learn what they demand until the front lines are gone.

One careless drop in the opening clogs the Conveyor Belt and ends the run before the mystery colors even flip.

The Trap in Marble Sort Level 46

The board is rigged to punish a greedy first move. Read it column by column:

• Column 1 and column 6: both capped by a Black block, and there is no Black Box anywhere at the start. Those Black blocks are dead weight sitting on top of the Pink and Purple you actually need.
• Column 2: Pink hides under a Red and a Green.
• Columns 3 and 4: Orange blocks at the very bottom — the one genuinely free lunch — with the blue Tunnels stacked directly above them, each showing a count of 3.
• Column 5: Pink buried under Purple.

The far-left Pink Box is the bait that kills most runs. Every reachable Pink is under at least one other color, so digging for it floods your belt with orphans. Ignore it. Play the center, feed the Boxes that match exposed blocks, and treat the belt as paid parking — two slots for the Black pair, nothing more.

Marble Sort Level 46 Step-by-Step Walkthrough

Your job in the opening is to get the center columns moving so the Tunnel counters start falling.

Opening: feed the center, park the Black

1. Tap the Orange block at the bottom of column 3, then the Orange at the bottom of column 4. Both go straight into the Orange Box.
2. Tap the Green block in column 2 into the far-right Green Box.
3. Tap the Purple block in column 5 into the Purple Box.
4. Now the calculated risk: park the Black block from column 1 on the belt, then the Black block from column 6. Two slots spent, deliberately.
5. The Pink in column 1 is finally exposed. Send it into the waiting Pink Box.
6. Column 6 now shows a Purple. Drop it to finish the Purple Box and close out the first wave.

Mid-game: Tunnels down, Mystery Boxes up

Clearing that wave shifts the whole board and the pressure spikes.

7. Keep pulling from columns 3 and 4 whenever an active Box matches. Every pull ticks a Tunnel counter down.
8. When a Tunnel hits zero it dumps three fresh marbles into play — expect a sudden flood of White and Light Blue from above.
9. The back rows push forward and a gray ”?” block surfaces. Stop. Do not pull anything from the Top Tray until the Mystery Box reveals its color.
10. If the reveal asks for White or Brown, take it from the top layers of the center columns — pull exactly what is needed, nothing extra.

Cleanup: belt discipline to the end

By now the tray is lopsided, with deep stacks of Yellow, Red, and Light Blue near the top and very little margin for error.

11. Never drop a Yellow or Light Blue onto the belt unless its Box is already exposed — the last Mystery Boxes love demanding colors that trap each other.
12. The moment a Black Box slides into the front row, cash in both parked Black blocks and reclaim your two belt slots.
13. Process one Box at a time: dig for the demanded color only if the belt can hold whatever sits on top of it. Clear the final Mystery Box to finish the level.

Level 46 Tips Recap

• The far-left Pink Box is bait — every reachable Pink is buried, so open with the center Orange pair instead.
• Parking the two Black blocks is the one planned sacrifice; keep every other belt slot liquid.
• Freeze when a Mystery Box appears: wait for the reveal, then pull only the exact color it wants.
