Marble Sort Level 133 Walkthrough & Solution

Level 133 Board Overview: The Mystery Box Wall

Level 133 opens with an ugly mismatch. Your bottom Boxes are hungry for Yellow and Purple on the left, and Green across the entire right side — but the Top Tray front row serves up Brown, Yellow, Light Blue, and Purple. Not a single Green in sight.

The middle of the board is a fat 4x3 block of gray Mystery Boxes, and behind them four ribbon-locked Panels each demand four Box clears before they shatter. Between the front row and that wall sit a few solid blocks: Yellow behind the Brown, Light Green behind the Yellow, Yellow behind the Light Blue, and Dark Blue behind the Purple.

Your receiver columns from left to right are: Yellow/Yellow/Light Green/Light Blue, then Purple/Yellow/Purple/Brown, then Green/Pink/Dark Blue/Yellow, then Green/Purple/Green/Yellow. The Conveyor Belt is tight, so every wrong tap is expensive.

The Trap in Marble Sort Level 133

The bait here is the Light Blue cluster in the front row. It is exposed, it is easy, and its only matching Box sits at the very bottom of the first column. Tap it now and those marbles camp on your belt for most of the level.

The second trap is the right side of the board demanding Green when zero Green marbles are visible. The only way to reach Green is through the Mystery Box wall, and the only way into the wall is by clearing the solid blocks in front of it. That means you have to eat some belt damage early — the front-left Brown has to move even though no Brown Box is open yet.

The good news: the second column ends with a Brown Box, so that sacrifice has a guaranteed payoff if you can hold out until the board shifts.

Marble Sort Level 133 Step-by-Step Walkthrough

Opening: dig through the front two layers

1. Tap the Yellow cluster, second from the left in the Top Tray. It clears the top Yellow Box in the first column.
2. Tap the Purple cluster on the far right of the tray. It fills the Purple Box leading the second column.
3. Tap the front-left Brown cluster and let it park on the Conveyor Belt. It has nowhere to go — that is fine. You are buying access to what hides behind it.
4. Tap the Yellow block that was sitting behind the Brown.
5. Tap the Yellow block hiding behind the front-row Light Blue. Steps 4 and 5 clear the second Yellow Boxes in the first and second columns.
6. Leave the Light Blue cluster untouched. Seriously — do not tap it.

Mid-game: mine the Mystery Boxes for Green

7. Tap the Mystery Boxes you just exposed, starting from the left and middle-left columns. You are hunting for Green.
8. The moment a Mystery Box reveals Green, send those marbles down to feed the Green Boxes leading the third and fourth columns.
9. Keep the clears flowing. Once enough Yellow, Purple, and Green Boxes are gone, the four locked Panels at the back shatter together.
10. The bottom queue shifts up — you are now looking at Light Green, Pink, Dark Blue, and more Purple Boxes.

Cleanup: cash in the parked Brown

The back of the board is open, showing fresh Orange, Pink, and Light Green clusters plus solid Dark Blue and Brown blocks.

11. Tap the Pink cluster that was hidden under the Panels to clear the Pink Box in the third column.
12. Tap the Light Green cluster into the Light Green Box now showing in the first column.
13. The Brown Box in the second column is finally exposed — the Brown marbles parked since step 3 flow into it automatically, and your belt is suddenly empty.
14. Tap the Dark Blue blocks from the upper tray into the Dark Blue Box in the third column.
15. Finally tap the front-row Light Blue cluster. Its Box at the bottom of the first column is open at last, and the level is done.

Level 133 Tips Recap

• The front-row Light Blue is poison — its Box is the deepest one on the board, so save it for last.
• Parking Brown on the belt early is a planned sacrifice, not a mistake. Just make sure you stop at one parked color.
• When the Mystery Box wall opens, chase Green above everything else. The right side of the board cannot move without it.
