Marble Sort Level 133 — Walkthrough and Solution

Marble Sort Level 133 is a puzzle of hidden colors and limited conveyor space. The key is to clear the left side aggressively to unlock the Mystery Boxes that hold the Green marbles needed for the right side. Avoid tapping the tempting Light Blue cluster early, as it will clog your belt.

The board has four columns of lower boxes. Column one starts with two Yellows, then Light Green and Light Blue. Column two has Purple, Yellow, Purple, and Brown. Column three is Green, Pink, Dark Blue, and Yellow. Column four is Green, Purple, Green, and Yellow. The top tray front row offers Brown, Yellow, Light Blue, and Purple clusters, but no Green. Behind them are solid blocks: Yellow behind Brown, Light Green behind Yellow, another Yellow behind Light Blue, and Dark Blue behind Purple. Then a 4x3 grid of grey Mystery Boxes covers the middle, and four locked Panels at the back require four box clears to open.

Marble Sort Level 133 Walkthrough

The bottom boxes demand Green on the right side immediately, but none are available initially. The left side has Yellows and Purples that are easy to clear. The right side's top boxes are Green, which you cannot touch yet. The only way forward is to dig through the left to expose the Mystery Boxes.

The Light Blue cluster in the front row is a trap. It looks harmless, but the only Light Blue box is at the very bottom of column one. Tapping it early sends Light Blue to the belt, which you cannot use until much later, filling your limited space. Ignore it completely until the end.

How to Beat Marble Sort Level 133 — Step-by-Step

Phase one: Clear the left side

1. Tap the Yellow cluster, second from the left in the top tray. It drops to clear the top Yellow box in column one.
2. Tap the Purple cluster on the far right of the top tray. It clears the top Purple box in column two.
3. Tap the Brown cluster, which is front-left. It sends Brown to the conveyor belt; you will need that space later, so leave it there.
4. Tap the Yellow block that was behind the Brown cluster. This clears the second-row Yellow box in column one.
5. Tap the Yellow block that was behind the Light Blue cluster. This clears the second-row Yellow box in column two.

Phase two: Crack the Mystery Boxes

1. Now tap the exposed Mystery Boxes, starting from the left and middle-left columns. Look for Green marbles to clear the top Green boxes on the right side.
2. When you find Green, tap it immediately to send it down to clear the Green boxes in columns three and four.
3. After clearing enough boxes, the four Panels at the back will shatter.
4. Now the bottom boxes shift up, revealing Light Green, Pink, Dark Blue, and more Purples.

Phase three: Late game cleanup

1. Tap the Pink cluster that was hidden behind the Panels. It clears the Pink box in column three.
2. Tap the Light Green cluster to clear the Light Green box in column one.
3. Now the Brown box in column two is exposed. The Brown marbles you parked on the conveyor belt will automatically flow into it, freeing belt space.
4. Tap the Dark Blue blocks from the top tray to clear the Dark Blue box in column three.
5. Finally, tap the Light Blue cluster from the front row. The Light Blue box at the bottom of column one is now open, and it clears to finish the level.

Tips & tricks

• Always prioritize clearing the left side first to expose Mystery Boxes quickly.
• Keep an eye on belt space; if it fills, you lose. Use the Brown penalty as a strategic hold.
• Do not tap Light Blue until the very end; it is the last color you need.
• When Mystery Boxes reveal Green, send them immediately to avoid belt congestion.

Common mistakes

• Tapping the Light Blue cluster early will clog your belt and ruin your run.
• Ignoring the left side and trying to clear right side Greens without Green marbles is impossible.
• Forgetting to use the Brown marbles on the belt when the Brown box opens wastes space.
