Level 287 Board Overview: Multiplier Gate and Mystery Box Trap

The verified walkthrough identifies the opening board as Multiplier Gate and Mystery Box Trap. The first confirmed moves are: Open by clearing the first row of bottom Boxes without touching the Green trap, feeding the front Purple receiver boxes from the bottom edge of the Top Tray. Then: Tap the Orange block sitting above the front row to clear the outer Orange Boxes, while keeping the three large Green blocks and all Mystery Boxes untouched. The next safe order is recorded below so the belt does not fill with bait.
The Trap in Marble Sort Level 287
- Opening bait: Once the Purple and Orange front row clears, the wall of Green Boxes is exposed, so tap the large front Green blocks to flow them safely into the newly opened Green Boxes.
- Board order: Since plenty of empty Green Boxes are ready, drop the Green waiting above the x2 gates to double it, but never send any color through a Multiplier Gate unless you visibly see its matching Box open.
- Belt discipline: Use only the first verified clears here; do not spend belt space on a color without an active receiver.
Marble Sort Level 287 Step-by-Step Walkthrough
Opening: follow the safe first clears

- Open by clearing the first row of bottom Boxes without touching the Green trap, feeding the front Purple receiver boxes from the bottom edge of the Top Tray.
- Tap the Orange block sitting above the front row to clear the outer Orange Boxes, while keeping the three large Green blocks and all Mystery Boxes untouched.
- Once the Purple and Orange front row clears, the wall of Green Boxes is exposed, so tap the large front Green blocks to flow them safely into the newly opened Green Boxes.
Midgame: open the next receiver path
After the opening clears, let the next exposed groups move only when their receiver is ready.
- Since plenty of empty Green Boxes are ready, drop the Green waiting above the x2 gates to double it, but never send any color through a Multiplier Gate unless you visibly see its matching Box open.
- When the third receiver clears, the top left and top right Panels open on their own, so watch the colors they spill and match those first to keep the upper board moving.
- In the late game, tap a Mystery Box only when your Conveyor Belt is completely empty to leave room for whatever color it spits out.
Cleanup: finish the remaining sequence
The final phase follows the remaining source order. Pause whenever the belt starts to fill.
- Finish one cluster completely before pulling the next one, working through the leftover Light Blue, Yellow, and Purple marbles from the top tray.
- Keep the belt clean and work the side Mystery columns slowly to fold the level easily.
