Level 305 Board Overview: Triple Gift Box Trap

The verified walkthrough identifies the opening board as Triple Gift Box Trap. The first confirmed moves are: Open by choosing the red receiver out at the lower-left corner of the tray, which pairs cleanly with the front-left red lower receiver. Then: Leave the central blue-and-yellow stack alone for now, and take the green and violet receivers that sit on the head line. The next safe order is recorded below so the belt does not fill with bait.
The Trap in Marble Sort Level 305
- Opening bait: Grab the cyan receiver and the other violet receiver over on the head right, since room is cramped but they must clear the way.
- Board order: Dropping those front receivers lights up the neighboring presents, whose 3s count down and burst to reshape the board.
- Belt discipline: Use only the first verified clears here; do not spend belt space on a color without an active receiver.
Marble Sort Level 305 Step-by-Step Walkthrough
Opening: follow the safe first clears

- Open by choosing the red receiver out at the lower-left corner of the tray, which pairs cleanly with the front-left red lower receiver.
- Leave the central blue-and-yellow stack alone for now, and take the green and violet receivers that sit on the head line.
- Grab the cyan receiver and the other violet receiver over on the head right, since room is cramped but they must clear the way.
Midgame: open the next receiver path
After the opening clears, let the next exposed groups move only when their receiver is ready.
- Dropping those front receivers lights up the neighboring presents, whose 3s count down and burst to reshape the board.
- Snap up the freshly exposed pink receivers at once and feed them to the two pink slots that wait in the head row, the real turning point of the stage.
- When the board rises to show a newer row of green and violet lower receivers, let the green and violet stones you parked on the belt surge into their slots.
Cleanup: finish the remaining sequence
The final phase follows the remaining source order. Pause whenever the belt starts to fill.
- Aim next at the yellow slot in the third lane, either excavating the yellow buried behind the central blue pile or pulling the yellow high on the upper right.
- Once the head receivers are gone, lift the deep-blue stones off the left wing to uncover the cyan underneath, park orange until its slot rotates forward, feed the leftover red and green from the right, and pour out the top yellow and violet to close the stage.
