This puzzle presents a stacked Top Tray that is wider on the left and right sides, with a central raised section that drops down like steps. The front row of bottom Boxes asks for Light Blue, Purple, and Orange immediately, and the key is to satisfy those demands using the outer columns while leaving the middle untouched until later.
On the far left, a Purple marble rests above a x2 gate, and on the far right, an Orange marble sits above another multiplier. Between them, the lower tier holds a Light Blue marble in the second column, a Dark Blue marble in the third, and two textured heavy blocks—one Purple and one Black—that will dump large clusters when triggered. The top layer also hides Pink, Green, and Brown marbles that appear after the center clears.
Marble Sort Level 155 Walkthrough
The bottom Boxes line up in four columns: the leftmost requests Purple, the next Light Blue, then Orange, with the fourth currently inactive. The active demands are for Light Blue, Purple, and Orange, but the Dark Blue marble must stay put until its matching Box appears.
That Dark Blue marble is a decoy—it looks reachable but dropping it early would jam the Conveyor Belt with no Box to receive it.
How to Beat Marble Sort Level 155 — Step-by-Step
Clearing the Front Row
- Tap the Light Blue marble located in the second column of the Top Tray; it falls straight into the waiting Light Blue Box.
- Now send the far-left Purple marble through the left multiplier gate, which fills the Purple Box instantly.
- Then guide the far-right Orange marble through the right multiplier gate to complete the Orange Box.
- Leave the Dark Blue marble alone for now; it will become useful later.
Releasing the Heavy Blocks
- As the bottom row shifts, a Black Box and another Purple Box slide into active positions.
- Wait until the appropriate Box is fully in place, then drop the heavy Purple block to release its cluster.
- After the dust settles, do the same with the heavy Black block, ensuring a Black Box is ready.
- Let the marbles from those blocks clear the Conveyor Belt before making any further moves.
Final Cleanup
- With the center opened up, Pink and Green marbles become visible in the upper layers.
- Prioritize the Green marbles, tapping them quickly to fill the newly appeared Green Boxes.
- If a Green or Pink marble drifts near an edge, use the multiplier gate to speed up the process.
- Finally, drop the Dark Blue marble into its now-exposed Box, and clear the remaining Brown marbles from the top corners to finish.
Tips & tricks
- Always clear the front row before touching the middle columns.
- Only trigger a heavy block when its matching Box is at the front and ready.
- Keep an eye on the Conveyor Belt—if it fills, you lose.
Common mistakes
- Dropping the Dark Blue marble early, which blocks the belt.
- Releasing a heavy block without an available Box, causing an overflow.
- Ignoring the multiplier gates and wasting taps on single drops.

Clear Light Blue first, as it is safe and in the middle, then use the multipliers for Purple and Orange on the edges.

It takes roughly 20 to 30 moves, depending on how efficiently you use the multiplier gates and avoid unnecessary taps.

No, boosters are not required if you follow the step-by-step order and manage the heavy blocks correctly.
What happens if I drop the Dark Blue marble early on Marble Sort Level 155?
