Marble Sort Level 739 Guide: The Mystery Box Trap

You are looking at a board designed to clog your lower slots immediately. This level throws a massive wall of hidden colors at you while burying your most needed matches. The dominant colors in the front are Brown, Green, Yellow, Orange, White, and Light Blue.

The Top Tray is split into two distinct nightmares. On the far left, you have a solid stack of Blue, Orange, and Blue blocks. The entire middle and right sections are choked by grey Mystery Boxes. Behind those sit two blue Tunnels marked with 3 and 4 timers. Worse, the game mixes empty bottom Boxes directly into the upper puzzle. You have to free them before you can even use them.

The Mystery Box Trap in Marble Sort Level 739

Every move on this board requires you to look at the bottom Boxes first. The bottom area is divided into four deep columns.

Here is exactly how your bottom tray is stacked from front to back:

• Column 1 (Left): Light Blue, Dark Blue, Green, Dark Blue.
• Column 2 (Mid-Left): Dark Blue, Light Blue, Red, Dark Blue.
• Column 3 (Mid-Right): White, Brown, Orange, Yellow.
• Column 4 (Right): Brown, Orange, White, Yellow.

Your active front-line Boxes are Light Blue, Dark Blue, White, and Brown.

Now look back at the Top Tray. The front row of marble clusters lines up horizontally: Brown, Green, Yellow, Orange, White, Light Blue.

Do you see the trap? The Green, Yellow, and Orange clusters are completely exposed in the front row. They look ready to play. They are pure bait. Their matching bottom Boxes are buried two or three rows deep. If you tap them, they will sit on your Conveyor Belt and instantly end your run.

The left stack of solid Blue blocks is your only way to clear the Dark Blue Boxes up front. But the real danger lies in the middle. The grey Mystery Boxes block access to the empty bottom Boxes waiting to drop down. A numbered gear block marked '2' sits directly over the right side, freezing that column. You must clear the front row selectively to unlock the board without jamming your limited space.

Marble Sort Level 739 Step-by-Step Walkthrough

Follow this exact order to dismantle the front lines and safely open the hidden sections.

First Moves and Clearing the Front Row in Marble Sort Level 739

You have to surgically remove the front row based on what the bottom tray actually wants.

1. Tap the Light Blue marble cluster on the far right of the Top Tray. It will drop and immediately clear the front Light Blue Box in column one.
2. Tap the White marble cluster. It will drop into the front White Box in column three.
3. Tap the Brown marble cluster on the far left. It sweeps down and clears the front Brown Box in column four.
4. Stop touching the front row. Leave the Green, Yellow, and Orange clusters exactly where they are.
5. Turn your attention to the solid stack on the far left. Tap the top Blue block. It will drop marbles to clear the active Dark Blue Box in column two.

Breaking the Mystery Boxes in Marble Sort Level 739

Your front line is clear. The bottom tray has shifted. You now have new active Boxes: Dark Blue, Light Blue, Brown, and Orange.

6. Tap the next Blue block in the left stack. This clears the newly exposed Dark Blue Box in column one.
7. Now you must gamble slightly. Tap exactly one grey Mystery Box from the bottom-most row in the middle. Wait to see what color it spits out.
8. If the Mystery Box reveals Brown or Orange, immediately route it into your active bottom Boxes.
9. If it reveals a color you do not need, leave it on the Conveyor Belt. Do not panic. You have space right now.
10. Clear the solid Orange block on the left to feed the active Orange Box.
11. Tap the exposed Light Blue cluster (revealed from behind the White marbles earlier) to clear the Light Blue Box in column two.

Surviving the Tunnels in Marble Sort Level 739

The board is hollowed out. The empty bottom Boxes trapped in the upper tray will now begin falling to the bottom.

12. Make matches next to the gear block marked '2'. You need to drop the marbles surrounding it to break its lock and free the right side of the board.
13. Keep chipping away at the Mystery Boxes one at a time. The goal is to clear a path to the two blue Tunnels at the top.
14. Watch your Conveyor Belt closely. When the blue Tunnels activate, they will dump a massive chain of marbles onto the belt. You must have at least four empty slots before breaking the final blocks underneath them.
15. Use the marbles from the Tunnels to fill the newly dropped bottom Boxes.
16. Clear the Yellow and Red clusters last. Their Boxes are at the very back of the bottom tray and will only activate in the final sequence. Drop them in to finish the level.
