Marble Sort Level 133 Guide: The Mystery Box Wall

Marble Sort Level 133 is entirely about managing terrible starting colors and surviving a massive wall of hidden variables. You load in and immediately see a problem. The bottom Boxes demand colors that you simply do not have in the front of the Top Tray.

Yellow and Purple dominate the left side of your lower board. Green blocks the entire right side. The top tray has some of what you need, but the rest is locked behind an incredibly thick 4x3 grid of grey Mystery Boxes. Capping off the entire board at the very back are four locked Panels that require four box clears just to open.

This level forces you to take early risks. You will have to intentionally dump useless colors onto the Conveyor Belt just to dig through the top layers. Do it wrong, and you run out of belt space immediately. Here is exactly how to strip this board down without jamming your game.

The unique board pattern in Marble Sort Level 133

Take a close look at how your lower Boxes are stacked. This dictates your entire survival strategy.

Your bottom Boxes sit in four columns. The first column starts with two Yellows, followed by Light Green and Light Blue. The second column goes Purple, Yellow, Purple, Brown. The third column is Green, Pink, Dark Blue, Yellow. The fourth column is Green, Purple, Green, Yellow.

Notice the immediate bottleneck. The entire right side requires Green marbles right now.

Now look at your Top Tray. The front row of tap-able marble clusters gives you Brown, Yellow, Light Blue, and Purple. There are zero Green marbles available.

Behind those clusters sit solid blocks: a Yellow behind the Brown, a Light Green behind the Yellow, another Yellow behind the Light Blue, and a Dark Blue behind the Purple.

Behind those solid blocks is the nightmare. Twelve solid grey Mystery Boxes cover the middle of the board. You have absolutely no idea what colors are inside them until you tap the blocks in front. Finally, behind the Mystery Boxes sit the four Panels wrapped in red ribbons, each demanding four lower Boxes be cleared before they shatter.

The bait on this board is the Light Blue cluster in the front row. It looks so tempting to tap. Do not touch it. The only Light Blue Box is buried at the very bottom of the first column. Tapping that Light Blue cluster early will permanently clog your Conveyor Belt while you try to dig for Green marbles. You must play the left side aggressively to crack the hidden middle.

You need to execute the opening perfectly. The Conveyor Belt gives you very little breathing room, and you have to dig deep just to find the colors your right-side Boxes are demanding.

Surviving the front lines in Marble Sort Level 133

The opening moves are all about taking calculated damage to your Conveyor Belt space.

1. Tap the Yellow cluster. It sits second from the left in the Top Tray. This will immediately flow down and clear the top Yellow Box in the first column.
2. Tap the Purple cluster. This is on the far right of the Top Tray. It drops down and clears the top Purple Box in the second column.
3. Eat the Brown penalty. You need the Yellow block sitting behind the front-left Brown cluster. Tap the Brown cluster. It will dump onto the Conveyor Belt. Let it sit there. Do not panic. You need that space opened up.
4. Clear the remaining Yellows. Tap the Yellow block that was hiding behind the Brown cluster. Then tap the Yellow block hiding behind the Light Blue cluster. This combination will clear out the second-row Yellow Boxes in both the first and second columns.
5. Ignore the Light Blue. I will say it again. Leave the front-row Light Blue cluster exactly where it is. If you send it to the belt now, you will lose the level.

Cracking the Mystery Boxes in Marble Sort Level 133

You have now punched a hole into the second layer of the board. The grey Mystery Boxes are finally exposed. Your goal here is hunting for Green.

6. Tap the newly exposed Mystery Boxes. Start pulling from the left and middle-left columns. You are looking for Green marbles to clear those stubborn top-row Green Boxes on the right side of the bottom board.
7. Feed the right side. As soon as the Mystery Boxes reveal Green marbles, tap them instantly. Send them down to clear the third and fourth columns. Getting those Green Boxes out of the way is mandatory.
8. Pop the Panels. By clearing the initial Yellows, Purples, and the newly found Greens, you will hit the magic number. The four Panels at the very back of the top tray will shatter.
9. Assess the mid-game shift. The bottom Boxes will now shift upward. You are now staring at Light Green, Pink, Dark Blue, and more Purple Boxes.

Managing the late-game squeeze in Marble Sort Level 133

The back of the board is now exposed. You will see fresh clusters of Orange, Pink, and Light Green marbles waiting for you, alongside solid Dark Blue and Brown blocks.

10. Clear the Pink. Tap the Pink cluster that was hiding under the Panels. This directly clears the Pink Box sitting in the third column.
11. Clear the Light Green. Send the Light Green cluster down to clear the matching Box that has now surfaced in the first column.
12. Free the trapped Brown marbles. You dumped a bunch of Brown marbles on the Conveyor Belt way back in step three. The Brown Box in the second column is finally exposed. Let those trapped marbles automatically flow into it, instantly freeing up massive amounts of belt space.
13. Clean up the Dark Blue. Tap the Dark Blue blocks from the upper tray to clear the Dark Blue Box in the third column.
14. Drop the Light Blue. You can finally tap that Light Blue cluster from the very front row. The Light Blue Box at the bottom of the first column is now open and waiting. Send it down to wrap up the board.
