Marble Sort Level 279 Walkthrough & Solution

Level 279 Board Overview: Dual Gold Cross Trap

The verified walkthrough identifies the opening board as Dual Gold Cross Trap. The first confirmed moves are: Open by pushing the huge Red marble pile into the Red Box and the huge Yellow pile into any Yellow Box, keeping your belt empty and ignoring the Purple, Brown, and Orange piles. Then: Find the smaller Yellow block holding a silver key in the lower-left middle section and drop it into a remaining Yellow Box to pull back one of the gold arms. The next safe order is recorded below so the belt does not fill with bait.

The Trap in Marble Sort Level 279

• Opening bait: Empty the newly exposed White and Brown receivers as soon as the front Yellow and Red boxes clear and the columns rise.
• Board order: Chase the key-bearing Grey and Pink blocks at the far right, then the Blue and Brown key blocks at the left, using each key to fold back another gold arm.
• Belt discipline: Use only the first verified clears here; do not spend belt space on a color without an active receiver.

Marble Sort Level 279 Step-by-Step Walkthrough

Opening: follow the safe first clears

1. Open by pushing the huge Red marble pile into the Red Box and the huge Yellow pile into any Yellow Box, keeping your belt empty and ignoring the Purple, Brown, and Orange piles.
2. Find the smaller Yellow block holding a silver key in the lower-left middle section and drop it into a remaining Yellow Box to pull back one of the gold arms.
3. Empty the newly exposed White and Brown receivers as soon as the front Yellow and Red boxes clear and the columns rise.

Midgame: open the next receiver path

After the opening clears, let the next exposed groups move only when their receiver is ready.

4. Chase the key-bearing Grey and Pink blocks at the far right, then the Blue and Brown key blocks at the left, using each key to fold back another gold arm.
5. When the right-side gold lock opens and reveals a grey Mystery Box, keep two belt slots free so any color it dumps can sit without jamming you.
6. Work through the Purple, Light Blue, Green, and Black marbles in the middle, clearing the specific White, Pink, and Black stacks the inner columns require.

Cleanup: finish the remaining sequence

The final phase follows the remaining source order. Pause whenever the belt starts to fill.

7. When deep-layer locked Blue and White boxes appear at the bottom, scan the Top Tray for their matching key boxes and route those colors down immediately.
8. Prioritize clearing the lower Boxes that match whatever jammed colors are on your belt, filling the Black Box the instant it opens to finish the board.
