Marble Sort Level 213 — Walkthrough and Solution

Marble Sort Level 213 presents a two-part challenge: a left column bound by horizontal keys and a right grid of Connected Boxes. The goal is to clear the front row of bottom Boxes without jamming the Conveyor Belt. Start by focusing on the right side's lower-left Light Green box, then use that to unlock the sequence.

The bottom Boxes from left to right demand Light Blue, Dark Blue, Light Green, and Light Blue. On the Top Tray, the left side has a vertical stack with Brown at the bottom, then Dark Blue, followed by Light Green, Yellow, and White near the top, all held by horizontal keys. The right side is a 3x5 grid with the bottom row holding Light Green, Brown, and Dark Red. Above them, two pairs are taped: Light Green with Light Blue, and Purple with Dark Red. The Conveyor Belt is the main risk; pulling taped boxes carelessly can drop many marbles at once.

Marble Sort Level 213 Walkthrough

Your first priority is to clear the third bottom Box (Light Green). That requires tapping the bottom-left Light Green box on the right side of the Top Tray. After that, you need Dark Blue to fill the second bottom Box. On the left side, the bottom two boxes are Brown and Dark Blue. You'll park Brown on the belt temporarily, then tap Dark Blue and route it to its receiver. That action also frees the bottom horizontal key on the left.

The main trap is the Connected Boxes on the right. Tapping them prematurely drops two boxes at once, flooding the belt. The safe approach is to clear the front row first, then handle the taped pairs one at a time when a matching receiver is active and the belt has space.

How to Beat Marble Sort Level 213 — Step-by-Step

Phase one: Break the Front Line

1. Tap the bottom-left Light Green box on the right side of the Top Tray.
2. Send those Light Green marbles into the third bottom Box (Light Green receiver).
3. Tap the bottom Brown box on the left side of the Top Tray, parking those marbles on the Conveyor Belt.
4. Now tap the Dark Blue box that was above that Brown, and guide those marbles to the second bottom Box.

Phase two: Manage the Connected Pairs

1. Pull the bottom Brown box from the right side of the grid and match it with the Brown already on the belt, then flush them into the newly revealed Brown bottom Box.
2. Tap the bottom-right Dark Red box and deliver those marbles to the Dark Red receiver when it appears.
3. Wait until the Conveyor Belt has at least five empty slots.
4. When a Light Blue receiver is active, tap the connected pair that holds Light Green and Light Blue. The Light Blue will sort, and the Light Green stays on the belt.
5. On the left side, tap the now-exposed Light Green boxes to match the Light Green on the belt, clearing another horizontal key.

Phase three: Unlock the Top Left and Finish

1. Pull the Purple and Dark Red connected pair only when the Dark Red receiver is open.
2. Park the Yellow or White box on the belt as needed to access the other, depending on what the bottom receivers demand.
3. Clear the remaining top-right grid boxes (Light Blue and Green) into their slots.
4. Finally, drop the remaining White and Pink boxes from the top-left into the last receivers to finish the level.

Tips & tricks

• Always keep an eye on the Conveyor Belt's empty slots before tapping any connected pair.
• Use the bottom receivers as a guide; only pull a box when its matching color is active.
• When you park a color on the belt, remember its position so you can match it later.

Common mistakes

• Tapping a connected pair without checking the belt space leads to a jam.
• Ignoring the left side's horizontal keys causes delays later.
• Pulling boxes for colors that aren't currently needed wastes moves and space.
