Marble Sort Level 69 is a bottleneck. You drop into a jagged, pyramid-shaped Top Tray loaded with Pink, Brown and Blue, and the lower area's outer edges are infested with Mystery Box traps. The front row wants Purple and Blue right away, but three Tunnels hold back crucial pieces and several marbles are tied together as connected boxes.
The front line of the Tray reads Blue, Purple, Brown, Cyan, Orange and a second Orange. The bottom Boxes want Purple, Blue, Purple and Purple. The trap is the Orange and Cyan at the front — there are no active Boxes for them, so they'd just sit on the belt. Your safe route is straight down the middle, where a big vertical stack of Blue sits in the right-center.
Marble Sort Level 69 Walkthrough
The left side has two Green marbles locked together as a pair, and on the right a Pink and Cyan share the same fate. Three Tunnels marked with a 3 sit at the top and edges, out of reach until the front clears. Everything hinges on cracking the outer Mystery Boxes safely so the hidden back rows open up.
Keep the belt clean and open up those hidden rows, or the late game catches you with a full line and no moves.
How to Beat Marble Sort Level 69 — Step-by-Step
Survive the front row bait
- Tap the lone Blue in the middle-right of the front row for the front Blue Box.
- Follow with the Blue marbles stacked behind it in that column to clear the Box fast.
- Release the Purple in the front right, then pick off the higher Purple marbles in the center grid.
- Leave the front Orange and Cyan alone, and don't touch the Green connected pair on the left yet.
Crack the Mystery Boxes and Tunnels
- The outer Mystery Boxes flip after the front line clears — read their new colours.
- If they demand Orange or Brown, feed them the front-row Orange and Brown you skipped.
- Now trigger the Green connected pair on the left, routing both into the newly opened middle Boxes.
- Clear the Pink and Brown tiles blocking the three Tunnels, then drop the Pink-and-Cyan pair only with a guaranteed Box for one of them.
Empty the Tunnels for the win
- Focus on the marbles dropping from the top and side Tunnels as they appear.
- Keep at least two belt slots open — the last Mystery Boxes can ask for colours you don't have yet.
- Match the tunnel marbles into the back-row Blue and Brown Boxes.
- Clear the final stragglers from the upper corners to finish, staying patient on the last taps.
Tips & tricks
- Read the front row's Orange and Cyan as bait, not targets — they have no home early.
- Trigger connected pairs only when the second colour has somewhere to land.
- Hold two belt slots open through the tunnel phase for unpredictable Mystery Box reveals.
Common mistakes
- Tapping the front Orange or Cyan. They loop on the belt with no Box and burn your limited space.
- Triggering the Green pair before the middle Boxes open, dropping two Greens with nowhere to go.

The Blue in the middle-right of the front row, then the Blue stack behind it. That clears the front Blue Box and opens the middle.
