Marble Sort Level 145 — Walkthrough and Solution

Marble Sort Level 145 presents a symmetrical pyramid in the Top Tray, edged with gray key blocks. The playable colors are Dark Green, Light Green, Purple, Pink, and Cyan, with White and Black at the peak. The bottom Boxes form four tight columns, and the front row demands one Light Green slot on the far left and three Dark Green slots to its right. The level's main challenge is a locked Blue Box buried under the second column, which can only be opened by releasing keys from the pyramid's outer edge. If you tap Purple or Cyan too early, their slots are still buried, and the Conveyor Belt fills up fast. The safe path is to clear the Greens first, then the Arrow Boxes, and finally the keys and peak colors.

The Top Tray's pyramid has a bottom row with a Purple Arrow Box on the left, three large Dark Green clusters in the middle, and a Light Green Arrow Box on the right. Above that row sit Cyan, Light Green, a Pink Arrow Box pointing upward, Purple, and another Light Green. The arrows point up, so these lower Boxes are inactive until the marbles above them are removed. The bottom Boxes have a front line of one Light Green and three Dark Green, with Purple, Cyan, and Blue visible underneath. The locked Blue Box sits under the second column, chained until keys are dropped. The key blocks form a perimeter around the pyramid, and the center holds the playable colors.

Marble Sort Level 145 Walkthrough

Start by examining the bottom Boxes: the far-left column requires Light Green, while the next three columns require Dark Green. Behind these, you see Purple, Cyan, and Blue slots, but they are not active until the front Boxes are filled. The locked Blue Box is under the second column, and it needs gray keys from the pyramid's edge to open. The Arrow Boxes at the bottom of the Top Tray are also locked until you clear the marbles directly above them. This means you must follow a strict order: first Light Green and Dark Green, then Purple and Pink, and finally Cyan and the peak colors.

The critical trap is that Purple and Cyan marbles are easily accessible early, but their bottom Boxes are buried behind the Green slots. Dropping them early fills the Conveyor Belt, causing an instant loss. Similarly, the key blocks seem tempting, but releasing them before the Blue Box is exposed wastes space. The puzzle forces you to play front-to-back, clearing the Green front line first to unlock the second layer of Boxes.

How to Beat Marble Sort Level 145 — Step-by-Step

Phase one: Clear the Green front line

1. Tap the accessible Light Green marbles located just above the bottom row on the left and right sides of the pyramid's inner core. Route them down to fill the far-left bottom Box.
2. Locate the three large Dark Green clusters in the bottom center of the Top Tray. Feed them one cluster at a time into the three active Dark Green slots in the bottom Boxes.
3. Pace the Dark Green drops so the Conveyor Belt does not overflow. Let each cluster settle before releasing the next.
4. Ignore the Purple and Pink marbles sitting above the Arrow Boxes. Their slots are still trapped, so leave them untouched for now.

Phase two: Unlock the Arrow Boxes

1. After clearing the Green front line, the second layer of bottom Boxes slides forward, exposing Pink, Purple, and Cyan slots. The locked Blue Box also moves closer to the front.
2. Clear the marbles above the bottom-row Arrow Boxes. This activates the Purple Arrow Box on the left and the Light Green Arrow Box on the right.
3. Release the Purple and Light Green marbles from those Arrow Boxes into their now-active bottom Boxes.
4. Begin tapping the gray key blocks on the outer perimeter of the pyramid. Drop them one at a time, ensuring the Conveyor Belt has empty spaces.
5. Unlock the Pink Arrow Box in the middle by clearing the marbles above it. Drop the Pink marbles into the active Pink bottom Box.

Phase three: Open the lock and clear the peak

1. As you drop keys, the lock on the Blue Box in the second column snaps open. Immediately release the Blue marbles from the upper right side of the pyramid into that Box.
2. Now drop the Cyan marbles that you deliberately avoided earlier. The Cyan bottom Box is finally in the active front slot.
3. With the lock gone and the mid-board cleared, the White and Black marbles at the very peak of the pyramid will have matching bottom Boxes slide into place. Drop them one by one, watching the Conveyor Belt space.
4. Finish by clearing any remaining colored marbles from the pyramid's edges, ensuring every bottom Box is filled.

Tips & tricks

• Always check which bottom Boxes are active before tapping any marble. Only release colors that have an open slot.
• Use the Conveyor Belt as a buffer, but never let it fill completely. Pause between drops if needed.
• When dropping keys, do so sparingly. Aim for a steady flow rather than dumping them all at once.

Common mistakes

• Tapping Purple or Cyan early, before their bottom Boxes are exposed, floods the Conveyor Belt and ends the game.
• Releasing all gray keys at once, which fills the belt and leaves no room for essential colored marbles.
• Ignoring the locked Blue Box until the end, causing a bottleneck when you need to drop keys and Blue simultaneously.
