Marble Sort Level 11 opens like a gift and then slams the door. Orange and Yellow carry the start, while Green, Light Blue, and Dark Blue lurk in the back. The front row offers a pair of Oranges and a pair of Yellows that line up with the bottom Boxes perfectly — and right behind that easy line waits a wall of eight Mystery Boxes you can't read. The design is meant to get you overcommitting on the opener.
The genuine danger isn't the Mystery wall, it's the back corners: a pair of Tunnels, each marked 3, stuffed with dark blue. Light either one too soon and its contents hit the belt with nowhere to land.
Marble Sort Level 11 Walkthrough
The front Boxes read Yellow, Orange, Orange, Yellow, which mirrors the tray's Orange, Orange, Yellow, Yellow. Clear that first line and the eight Mystery Boxes roll into view. Underneath them sits a second layer of Yellow, Orange, Yellow, Yellow, and further back the far-left column carries a thick Dark Blue Box, the middle columns hold Green and Dark Blue, and Light Blue is tucked away on the right.
The trap is timing those two Tunnels. They sit up top, so they read as late-game, but they come loose the instant the middle clears. Tap one before you've dug down to a Dark Blue receiver and the belt fills on the spot. The centre of the tray also keeps one Yellow and one Light Blue behind the mystery zone, and that tight little space is where the level is decided.
How to Beat Marble Sort Level 11 — Step-by-Step
Open the Mystery zone
- Tap the two Yellows on the outer edges, then the two Oranges on the inside of the front row.
- They fall into the matching front Boxes and wipe out the first layer.
- Now pause. The second layer climbs up and the eight Mystery Boxes flip open.
- Only release a colour that fits the Yellow or Orange Box currently leading the front.
- Keep your hands off both dark blue Tunnels.
Manage the Tunnels and the belt
- Clear the leftover Yellow and Orange from the centre to bring the Light Blue block into view at the top middle-right.
- Hold off on any Tunnel until a Dark Blue Box is fully exposed at the head of its column.
- Tap the left Tunnel; its dark blue drops cleanly into that Dark Blue Box.
- Release the Green and Light Blue that surface only once their Boxes have moved forward. The deep Green Box in the middle-right column tends to stall you, so work toward it.
- Keep the belt's right side open, or the right Tunnel stops being usable.
Clear the late-board jams
- Tap the right Tunnel only when the belt has three empty slots to spare.
- Feed its dark blue into the last Dark Blue Box.
- Guide the top-middle Light Blue into the bottom-right Light Blue Box to trigger the final clear.
- Finish off the remaining Green to close the board.
Tips & tricks
- The front row is a speed trap — clear it, then slow way down before the Mystery zone.
- Treat each Tunnel's 3 as a fuse you don't light until a Dark Blue Box is waiting.
- The middle-right column's deep Green Box is this level's quiet blocker.
Common mistakes
- Setting off a Tunnel before a Dark Blue Box is exposed. The payload floods the belt instantly.
- Piling mismatched colours onto the right side of the belt, which locks the right Tunnel out of play.
Marble Sort Level 11 FAQ
Why does my Conveyor Belt flood on Marble Sort Level 11?
You tapped a dark blue Tunnel before a Dark Blue Box was exposed, so its payload dumped onto the belt with nowhere to go. Clear the middle first and wait for a Dark Blue receiver.
Which color do I clear first on Marble Sort Level 11?
Yellow and Orange, in the front row. Clearing the two outer Yellows and two inner Oranges opens the eight Mystery Boxes and exposes the real board.
How many moves does it take to clear Marble Sort Level 11?
Around a dozen taps across three phases — the front-row clears, the two Tunnel dumps, then the Light Blue and Green cleanup.
Do I need boosters to beat Marble Sort Level 11?
No. Clear the front row, then hold both Tunnels until Dark Blue Boxes surface. Save boosters for boards with hidden Boxes or locks.
What happens if I trigger a Tunnel too early?
The dark blue marbles hit the Conveyor Belt with no Box to catch them, so the belt jams and you fail before the correct Boxes ever appear.
