Then: Right after that, tap the center Light Pink block beside the one you just used, which clears the Light Pink Box active in column four.

The Trap in Marble Sort Level 323

• Opening bait: Move to the far-left flank and drop the loose Red block on the edge, emptying the Red Box in column two.
• Board order: Leave the front-right Green block alone for now, since no Green Box is active until a lane cycles one to the top.
• Belt discipline: Use only the first verified clears here; do not spend belt space on a color without an active receiver.

Opening: follow the safe first clears

1. Open by taking the front-left Green block at the Top Tray center and dropping it to empty the Green Box in column one at the far left.

Midgame: open the next receiver path

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

4. Leave the front-right Green block alone for now, since no Green Box is active until a lane cycles one to the top.
5. Tap the Light Blue block inside the blue border to clear the Light Blue Box in column three and keep the board moving.
6. Clear the blocks sitting immediately before the gray Hidden Boxes; drop any revealed color that already has an active bottom box, but let Orange or dark Blue stay in the tray.

Cleanup: finish the remaining sequence

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

7. Cycle the Purple Boxes by pairing them with the Purple blocks up on the top-right flank, and check column three whenever a White block opens in the middle.
