Marble Sort Level 29 — Walkthrough and Solution

Marble Sort Level 29 tricks you into clogging your own game. Dark Blue, Brown, Red, and Orange crowd the board, five grey Mystery Boxes line the back row, and a Tunnel stamped 3 sits in the second column, sealing the back until three full clears. The active Boxes want Orange, Light Purple, Orange, and Dark Blue. Release the wrong front marble and the belt overruns in seconds.

Across the front you've got Red, a Dark Blue, a Brown, and another Dark Blue. Your Boxes are after Orange and Light Purple, yet the front is walled off with Red and Brown instead. Tap that front-left Red and you're dead — its Box sits all the way down the far-right stack, so it just camps on the belt. The Brown is the same trap, buried under Light Purple and Orange.

Behind the front line, the second row carries Brown, then Light Purple, then Dark Blue, Orange, and Green. The third row holds a Mystery Box, the locked Tunnel, and two more Mystery Boxes, with a full wall of five Mystery Boxes on top. The whole early game is about surgically removing the Dark Blues so the Light Purple and Orange hiding in row two come into view.

How to Beat Marble Sort Level 29 — Step-by-Step

Dodge the bait

1. Tap the Dark Blue that's second from the left in the front row.
2. Then tap the Dark Blue at the far-right end of that same row.
3. Both groups drop to the belt and feed the far-right Dark Blue Box.
4. Don't touch the far-left Red or the front Brown — both are bait that starve you of space.
5. Once that right-side Dark Blue clears, a Green Box rises, and the second row now exposes a Light Purple on the left. Tap it.
6. Send the Light Purple down to clear the middle-left Box, which uncovers a Dark Blue Box in that stack.
7. Tap the Dark Blue sitting mid-second-row to fill that just-opened Dark Blue Box.

Crack the Tunnel

1. Three clears done, and the Tunnel's 3 hits zero, spilling more Light Purple and Dark Blue.
2. The middle-right Box still wants Orange. Tap the Orange in the second row to clear it and pull up a Brown Box.
3. That front-row Brown you ignored is finally safe — drop it into the middle-right stack, which clears it and surfaces a Light Purple Box.
4. Finish it with the Light Purple the Tunnel just revealed.

Survive the Mystery wall

1. With the Tunnel open and the second row empty, the five back Mystery Boxes start revealing a rush of Light Blue and Purple.
2. The far-left and far-right stacks now ask for Green. Drop the Green sitting at the right end of the second row.
3. Scan the Mystery reveals for Light Blue; your lower stacks will surface Light Blue and Purple boxes deep in the rotation.
4. Hold any revealed colour that has no active Box.
5. Drop the trapped front-left Red only when the far-right stack reaches its final Red box.
6. Feed the backline Purples into the remaining Boxes to finish.

Tips & tricks

• The Dark Blues are your only safe first taps; both feed the far-right Box and start the chain.
• Red and Brown on the front are decoys with Boxes buried far down — hold them until late.
• Time the Tunnel trigger around the three Dark Blue and Light Purple clears.

Common mistakes

• Tapping the front Red or Brown early. Both park on the belt and starve you of space for the real chain.
• Releasing a Mystery colour with no active Box, which strands it on an already-tight belt.
