Marble Sort Level 86 suffocates your early game. A 16-clear Panel plugs the middle, so you clear sixteen whole Boxes before those nine centre spaces open up. That's forty-eight sorted marbles while missing the biggest chunk of the board, and the only safe working area is the bottom row of the Tray.
The bottom row reads Purple, two Greens, Black, Red, Brown and Blue, with glimpses of Yellow, Blue, White, Pink, Blue, Light Blue and White behind it. Your opening Boxes want Purple, Brown, Blue and Green, with Light Blue, White, Brown and Blue stacked under them. Three Tunnels sit up top, waiting for the grid below to clear.
Marble Sort Level 86 Walkthrough
The vertical Mystery columns on the left and right are the danger. Tap one and it can drop a Black or Pink with no home, burning a slot. Pull that off twice and you're finished before the Panel ever opens. Take the exact matches the bottom row gives you, then read every Mystery reveal before the next tap.
Grind the edges, hit sixteen clears, and the center Plate drops.
How to Beat Marble Sort Level 86 — Step-by-Step
Beat the opening squeeze
- Take the lone Purple in the bottom row's right-center for the Purple Box on the far left.
- Tap the Brown on the far right for the second column's Brown Box.
- Grab the Blue next to it for the third column's Blue Box.
- Tap the two Greens on the bottom left for the far-right Green Box.
- Pull the exposed White and Light Blue from the second row to finish the first layer.
Survive the Mystery Boxes
- Prioritise the Light Blue and White Boxes, matching them from the second and third rows.
- Only tap a Mystery Box with three empty belt slots, assuming it'll drop a useless colour.
- If a Mystery Box drops a dead colour, leave it and find another safe match to cycle the Boxes.
- If it drops a colour matching an open target, funnel it in immediately.
- Grind the edges until the Panel hits zero.
Drop the Panel for the finish
- The center opens to Orange, Red, Dark Green and Yellow — route the big Orange cluster into the new Orange Box.
- Clear the center's Dark Green to free up the space beneath the Tunnels.
- The Tunnels dump their marbles as the space below clears — catch the influx.
- Mop up the remaining yellow and red clusters to finish.
Tips & tricks
- The bottom row's Purple, Brown, Blue and Greens are your only safe opening — take them first.
- Give every Mystery Box three open slots, since it can drop any colour.
- Track the Panel number and grind the edges until it hits zero.
Common mistakes
- Tapping a Mystery Box with no slots and dropping a dead Black or Pink, burning a slot permanently.
- Ignoring the Tunnels after the Panel drops, so they dump colours you're no longer ready for.
