Marble Sort Level 288 drops you into a symmetrical battleground where a central column of Mystery Boxes splits the board, and two giant 2x2 Connected Boxes loom on either side. The key to victory is to first clear the loose front-row marbles that match the bottom Boxes' initial demands, then methodically trigger the Connected Boxes only when the Conveyor Belt has room and the lower targets are ready. Ignore the tempting Orange and Purple marbles on the edges—they are decoys that will choke your belt.

The Top Tray is a mirror image divided by a vertical spine of seven Mystery Box tiles. On the left, a blue-striped 2x2 block holds Black, two Reds, and a Light Pink. On the right, another 2x2 block contains two Light Pinks and two Light Blues. Below these, loose marbles sit exposed: Orange, Light Blue, Light Pink, and a bottom row with Red, Light Pink, Black, and another Red. The bottom target Boxes initially demand Black (two on the far left), Red (next to them), and Light Pink (far right). Behind them, Light Blue, Red, and Green wait in the wings.

Marble Sort Level 288 Walkthrough

Your opening moves must feed the front-line Boxes using only the loose marbles near the bottom of the Top Tray. The leftmost Black Box, the adjacent Red Box, and the far-right Light Pink Box are your first goals. Do not tap the Orange or Purple marbles—they have no home yet.

The critical trap is the left 2x2 Connected Box. If you trigger it too early, all four marbles (Black, two Reds, Light Pink) will flood the Conveyor Belt, and with no empty lower Boxes, the belt jams. Wait until you've cleared at least two of the front Boxes to ensure space for the incoming colors.

How to Beat Marble Sort Level 288 — Step-by-Step

Phase one: Clear the Front Row

  1. Tap the loose Black marble near the bottom center-left to feed the first Black Box.
  2. Send the two loose Reds from the bottom corners into the Red Box.
  3. Route the loose Light Pink from the bottom row to the far-right Light Pink Box.
  4. Drop the lowest Mystery Box on the central spine. If it reveals Black, Red, or Light Pink, guide it to the matching Box.
  5. Fully empty the front Black Boxes before touching the left-side block.

Phase two: Detonate the Connected Boxes

  1. Confirm at least four empty slots on the Conveyor Belt.
  2. Release the left 2x2 Connected Boxes—Black, Red, Red, Light Pink drop at once.
  3. Let these colors settle into the newly opened Red and Light Pink Boxes.
  4. Shift to the right side. When a Light Blue Box slides forward, trigger the right 2x2 block, releasing two Light Pinks and two Light Blues.
  5. Sort these into the waiting bottom Boxes, clearing the right flank.
  6. Now chip away at the central Mystery Box column one tile at a time, matching each color before dropping the next.

Phase three: Handle the Late-Game Color Shift

  1. Once the upper middle clears, the lower Boxes switch to Purple and Brown.
  2. Find the Purple marbles that were trapped behind the right Connected Block; feed them into the new Purple Box on the right.
  3. Locate the Brown marbles in the upper left and slide them into the two Brown Boxes in the center-left.
  4. Keep the Conveyor Belt empty as you drop the final Mystery Boxes from the top of the spine—they hide the Green or Yellow you need to finish.
  5. Drop each Mystery Box with care, watching its color and matching it to the remaining target Boxes.

Tips & tricks

  • Always clear the front-row Boxes before triggering any Connected Block to avoid belt overflow.
  • Leave the Orange and Purple edge marbles untouched until the late game when their target Boxes appear.
  • When dropping Mystery Boxes, pause after each one to reassess the board—never spam taps.

Common mistakes

  • Grabbing the Orange or Purple marbles early, which clogs the belt and delays your progress.
  • Releasing a Connected Block without checking the Conveyor Belt space, causing a jam.
  • Rapid-firing the central Mystery Box column, leading to mismatched colors piling up.
