⚡ Quick clear

Light Blue → Blue. The lock won't open without its key.

Marble Sort Level 234 presents a confined board with a dominant V-shaped layout. The middle row is locked by a chain, and a key panel sits in the top-left corner. The primary colors are Light Blue, Red, Dark Blue, and Orange, with limited room for error.

The top tray shows a White box on the right edge, which is a trap. The bottom columns have two Light Blue boxes at the top of Column 1 and Column 2, an Orange box at the top of Column 3, and a Purple box at the top of Column 4. The goal is to clear the outer boxes to unlock the key, which will break the chain and open the board.

Marble Sort Level 234 Walkthrough

Start by tapping the two exposed Light Blue boxes in the top tray. They match the Light Blue boxes at the top of Column 1 and Column 2. After they drop, the next boxes in those columns become exposed: a Dark Blue box in Column 1 and a Red box in Column 2. Tap those to clear them. Meanwhile, ignore the White box on the right side of the top tray—it has no match yet.

The key insight is that the White box is a decoy. Sending it to the belt early will clog a slot, and you need every slot free to manage the upcoming chain of matches. Wait until a White box appears in the bottom columns later.

How to Beat Marble Sort Level 234 — Step-by-Step

Phase one: Unlock the key

  1. Tap the two Light Blue boxes at the bottom center of the top tray. They drop into the matching Light Blue boxes in Column 1 and Column 2.
  2. Now tap the Dark Blue box that appears in Column 1 and the Red box in Column 2. They match the exposed boxes in the bottom columns.
  3. Next, focus on the right side of the top tray. Tap the Purple box and the Orange box, which match the top boxes in Column 3 and Column 4.
  4. Continue clearing the outer edges of the V-shape: tap any exposed boxes that match the visible bottom columns, such as Red, Dark Blue, Light Green, and Yellow, as they become accessible.
  5. Work systematically to strip away the boxes guarding the top-left key panel. Once enough boxes are cleared, the key activates and flies to the chain, breaking it.

Phase two: Clear the midgame

  1. After the chain breaks, the top-left panel disappears, revealing a cluster of new boxes, including Light Green and a double stack of Orange.
  2. Look at the center of the top tray: a cluster of Red boxes is now exposed. Tap them to clear them into the matching Red boxes that have shifted up from the bottom.
  3. Check your belt: you may have Yellow, Light Green, and Dark Green marbles from earlier matches. Plan your next moves to keep the belt clear.
  4. Now tap the White box you left in the top tray. It will match a White box that has appeared in the bottom columns after the previous clears.
  5. Clear the Light Green boxes from the top-left area by tapping them into the matching Light Green bottom boxes.

Phase three: Finish the mystery stacks

  1. As the bottom columns fill with grey Mystery Boxes, work from the top down. When an Orange bottom box is open, tap all available Orange boxes from the top tray.
  2. Do not tap colors just to reveal what is underneath; every move must match an open bottom box to avoid belt jams.
  3. Clear the Light Pink boxes on the right side when they become available.
  4. Finish off the remaining Light Green and Dark Blue boxes, revealing the final colors in the mystery stacks. Keep the belt lean, and the board will clear.

Tips & tricks

  • Always match the bottom-most exposed boxes first to keep the columns moving.
  • Use the belt as a temporary holding area, but never let it fill—plan two moves ahead.
  • When a Mystery Box appears, match it as soon as its color is revealed.

Common mistakes

  • Tapping the White box too early, which clogs the belt.
  • Clearing random boxes without matching them, causing the belt to fill.
  • Ignoring the key sequence and trying to brute-force the middle section.
