This board is a dense arrangement of colored marbles, directional blocks, and two numbered pipes in the middle. You must prioritize clearing the outer edges before touching the center to avoid a belt overload.
Marble Sort Level 637 features a Top Tray with multiple rows of marbles, including solid colors and split-color pieces. The bottom row of the Top Tray has dotted blocks: Dark Blue on the far left, two Yellow in the middle-left, and two Light Blue on the far right. Above these, obstacles include a white Arrow Box pointing left on the left, a green Arrow Box curving left on the right, and two blue pipes labeled 3 in the center, trapping a split Orange/Light Blue marble. The front bottom Boxes require Dark Blue, Light Blue, Green, and Yellow.
Marble Sort Level 637 Walkthrough
Look at the bottom Boxes: the leftmost demands Dark Blue, the next needs Light Blue, then Green, and finally Yellow. The safe initial grabs are Dark Blue and Light Blue from the bottom outer edges.
The main trap is the central 4-way Arrow Box. Touching it early or forcing split-color marbles down can clog your Conveyor Belt. The key is to release marbles from the outer columns first to give the Arrow Boxes room to drop.
How to Beat Marble Sort Level 637 — Step-by-Step
Phase one: Unlock the outer columns
- Tap the Dark Blue dotted block at the bottom left, sending it to the Dark Blue Box.
- Tap the two Light Blue dotted blocks at the bottom right, routing them to the Light Blue Box.
- Pick up the solid Dark Blue marble on the left edge, then the solid Pink marble on the bottom right edge, parking them on your belt.
- Now trigger the white Arrow Box on the left, as the space beneath is clear.

- Grab the solid Light Blue and Green marbles flanking the center.
- Match the split Purple/Green piece near the top, ensuring a Purple Box is active.
- Finish by dropping the split Orange/Dark Blue and Light Blue/Pink pieces to complete the level.
