Marble Sort Level 16 opens with a suffocating gap between what you can reach and what the board wants. Green, Purple, Cyan, Blue, and Dark Grey run the table, two numbered Tunnels sit on the outer edges, and you win or lose it in the first five taps. The trap is forced parking — you have to clog the belt on purpose just to reach the marbles that open the board.
The only row you can tap is a wall of Cyan, Blue, Cyan, Blue, and Dark Grey, read left to right. The front Boxes want Cyan, Purple, and a pair of Dark Greens. That's the cruel part: the Boxes want Dark Green and Purple, but the tray buries them behind Dark Grey and Blue, leaving Cyan as the lone natural match.
Marble Sort Level 16 Walkthrough
The columns tell you the order. The far-left holds Dark Grey, then Pink, then Dark Green, then a Tunnel needing three clears. The second holds Blue, then Purple, then Purple, then Blue. The third stacks Cyan, Dark Grey, Purple, Dark Green. The fourth holds Blue, Dark Green, Red, Red. The fifth ends Cyan, a Tunnel, and Dark Grey on top. Behind the front row sits a second layer wanting Dark Grey and Cyan, then a third wanting Red and more Cyan — all locked until the front clears, which is exactly why you have to sacrifice belt space.
How to Beat Marble Sort Level 16 — Step-by-Step
Bust the Cyan gate
- Tap the Cyan at the bottom of column three, then the Cyan at the bottom of column five. They clear the front Cyan Box instantly.
- Now the board is frozen: Purple and Dark Green sit locked in the second row.
- Move the bottom Blue out of column two and onto the belt, then do the same with column four's Blue.
- Send the bottom Dark Grey from column one to the belt.
- Stop. The belt is dangerously full, but row two's armour is gone.
Feed the Green and Purple Boxes
- Tap the Purple now exposed in columns two and three into the front-right Purple Box.
- Take the Dark Green from column three, then the one from column four, and drop them into the pair of Dark Green Boxes at the front-left.
- Once the first line clears, the second row rises and its Dark Grey and Cyan slots go live.
- Tap the Dark Grey and Blue you parked earlier; they flush into their new Boxes and the belt is clean.
Survive the mid-game and Tunnels
- A wall of Pink, Blue, and Dark Grey Boxes now climbs to the front.
- Strip the Purple, Green, and Red from the centre columns to wind down the two Tunnels' counters.
- Pull the Pink out of column one to bring the last Dark Green into view.
- As you dig, you'll hit a run of Green — only route it when a Green Box is visible or about to surface.
- Both Tunnels reach zero and tip their heavy Red blocks onto the column tops.
- Route that Red into the final Red Boxes and the board is done.
Tips & tricks
- Cyan is the only natural opening match — clear both Cyans before anything else.
- Parking the Dark Grey and Blue is the route, not a mistake; the second row repays them.
- Both Tunnels need three clears each, so keep feeding the front rows to wind them down.
Common mistakes
- Panic-clearing before the front Cyan clears. The junk has no Box yet and fills the belt.
- Routing the midgame Green into a non-Green Box, which strands it and stalls the Tunnels.
Marble Sort Level 16 FAQ
Why does my Conveyor Belt flood on Marble Sort Level 16?
You tapped the Dark Grey and Blue blockers before clearing the front, so they had no Box to catch them. Clear the two Cyans first, then park the junk deliberately.
Which color do I clear first on Marble Sort Level 16?
Cyan, on the bottom of columns three and five. It's the only front-row colour that matches, and clearing it starts the whole blockade breakdown.
How many moves does it take to clear Marble Sort Level 16?
Around twelve taps across three phases — the Cyan clear and forced parking, the Purple and Dark Green feed, then the Red and Green tunnel cleanup.
Do I need boosters to beat Marble Sort Level 16?
No. Park the junk colours, clear the front, and both Tunnels wind down on their own. Save boosters for boards with hidden Boxes or locks.
What happens if I tap the Dark Grey or Blue blockers early?
They drop onto the Conveyor Belt with no matching Box, so the belt fills before you can reach the Purple and Dark Green buried behind them.
