Marble Sort Level 294 Walkthrough & Solution
Level 294 Board Overview: Vertical Tunnel Spine

The verified walkthrough identifies the opening board as Vertical Tunnel Spine. The first confirmed moves are: Open by choosing the red pile that sits freely on the tray’s lower-left area, guiding it into the far-left red receiver so that lane empties. Then: Pick the dark green pile that sits in the middle of the bottom line, which tops off the far-right dark green receiver and removes it from play. The next safe order is recorded below so the belt does not fill with bait.
The Trap in Marble Sort Level 294
- Opening bait: Leave the cyan, orange, and light green piles alone for now, because no matching receivers exist yet and dropping any would strand the stone.
- Board order: After that first row empties, dark green turns up at the left edge while orange takes the right edge, so push the orange pile down into the fresh orange receiver.
- Belt discipline: Use only the first verified clears here; do not spend belt space on a color without an active receiver.
Marble Sort Level 294 Step-by-Step Walkthrough
Opening: follow the safe first clears

- Open by choosing the red pile that sits freely on the tray’s lower-left area, guiding it into the far-left red receiver so that lane empties.
- Pick the dark green pile that sits in the middle of the bottom line, which tops off the far-right dark green receiver and removes it from play.
- Leave the cyan, orange, and light green piles alone for now, because no matching receivers exist yet and dropping any would strand the stone.
Midgame: open the next receiver path
After the opening clears, let the next exposed groups move only when their receiver is ready.
- After that first row empties, dark green turns up at the left edge while orange takes the right edge, so push the orange pile down into the fresh orange receiver.
- Begin lifting pieces that sit directly under the center column of pipes, since every lift makes their numbers fall from 2 toward 0.
- For the next row calling for dark blue and dark green, lift the dark green piece that sits over the spot where the first red pile was, then start chasing the lock-and-key tiles on the edges.
Cleanup: finish the remaining sequence
The final phase follows the remaining source order. Pause whenever the belt starts to fill.
- When a cyan receiver appears, grab the upper-right cyan lock-and-key tile right away, and take the left-side yellow tile the moment a yellow receiver shows, freeing the frozen side lanes.
- Once the two ‘3’ pipes burst open, clear the leftover violet and green piles, send the now-released edge tiles onto the belt, and pour the last light green piles into their receivers to finish the board.
