Marble Sort Level 639 is a grid puzzle that tests your patience and inventory control. The key to victory is to ignore the left side at the start and focus your taps on the right side to uncover Red and Green marbles quickly.
The board presents a top tray with a fully visible row of marbles: Orange on the far left, then Pink, Brown, Dark Blue, Pink again, Light Blue, and finally Red on the far right. Below, the bottom boxes are initially exposed, demanding Green, Red, Red, and Red from left to right. The middle rows are blocked by Arrow Boxes pointing sideways (Pink and Purple) and vertically (Orange and Green), while Mystery Boxes cover most other tiles. Surprise Bags sit in the top corners and center.
Marble Sort Level 639 Walkthrough
The bottom boxes at the start are a clear signal: you need a large quantity of Red and a single Green to open up the board. However, only one Red is visible in the front row, and the Green is hidden behind the clutter. The front row is a decoy; tapping the left side too early will cause your Conveyor Belt to jam with colors that have no available destination.
The imbalance lies in the fact that the colors you need most are buried deep, while the colors you don't need are exposed. To succeed, you must carve a path on the right side to access the hidden Reds and Greens, using your Conveyor Belt as a temporary holding area for other colors you are forced to move.
How to Beat Marble Sort Level 639 — Step-by-Step
Phase one: Dig on the right for Reds
- Tap the Red box located on the far right of the top tray to feed one of the waiting bottom Red boxes.
- Next, tap the Light Blue box and the Pink box that sit beside that Red. They will occupy your Conveyor Belt, but you must move them to expose the tiles behind.
- Start flipping over the Mystery Boxes on the right side. Your aim is to find Red and Green marbles to satisfy the bottom boxes.
- Whenever you uncover a Red or Green marble, route it down immediately to clear the top layer of bottom boxes as fast as possible.
- Do not touch the Orange, Brown, or Dark Blue boxes on the far left. Their bottom boxes are still buried deep, and moving them now would clog your belt.
Phase two: Clear the belt and navigate the arrows
- After clearing the initial Reds and Greens, the bottom boxes now request Light Blue, Dark Green, and Pink. Use the Light Blue and Pink marbles you parked on the belt earlier to fill these slots and free up space.
- Activate the Pink Arrow Box and the Purple Arrow Box only when you have a clear path to drop their contents into the matching bottom boxes.
- Delve into the center Mystery Boxes to reveal Yellow, Purple, and White marbles.
- Keep a close eye on your Conveyor Belt. It will fill with a mix of Orange, Light Blue, Dark Green, Yellow, and White. Ensure you always have at least two empty slots to avoid overflow.
- Refrain from opening the Surprise Bags at this stage. If your belt is crowded, they will dump random colors and cause an instant loss.
Phase three: Finish the left side and surprise bags
- Now that the left bottom boxes are accessible, release the Orange from the front left. The Orange bottom box is finally ready on the left stack.
- Clear the Yellow and White tiles that block the top middle area.
- Now you can open the Surprise Bags in the top corners. Crack them one at a time, and guide the spilled marbles directly into the corresponding bottom boxes.
- Focus on clearing the deepest columns on both the left and right edges.
- Finish by cycling any remaining Dark Blue and Purple marbles into their final stacks, maintaining a steady rhythm until the board is clear.
Tips & tricks
- Always prioritize clearing the bottom boxes that match the colors you are moving, even if it means holding other colors on the belt temporarily.
- Use the Conveyor Belt as a buffer, but never let it fill completely. Keep a mental count of your open slots.
- When you open a Surprise Bag, do it when your belt has plenty of room, and be ready to route the colors quickly.
Common mistakes
- Starting with the left side is a fatal error; you will run out of belt space before you can clear the necessary colors.
- Opening Surprise Bags too early can flood your Conveyor Belt with unwanted colors, leading to a dead end.
- Ignoring the Arrow Boxes and trying to force marbles through them without planning can block your path and waste moves.
