Marble Sort Level 507 — Walkthrough and Solution

Marble Sort Level 507 presents a vertical grid topped by seven columns, with four striped Tunnels anchoring the sides and three columns of Surprise Bags between them. The bottom receiver row initially asks for Green, Purple, Red, and Red from left to right. Your opening move must target the exposed clusters along the bottom edge of the top tray, avoiding the tempting central Pink, White, and Blue groups that have no active Boxes yet.

The safe zones are the far left and far right edges. The leftmost bottom cluster is Green, feeding the top-left Green Box. The far-right bottom cluster is Red, filling the far-right Red Box. Next, the inner-left Red cluster satisfies the inner-right Red Box, and the inner-right Purple cluster fills the inner-left Purple Box. Leave the center untouched, as tapping it prematurely will clog the Conveyor Belt and stall progress.

Marble Sort Level 507 Walkthrough

After clearing the initial four clusters, the lower Boxes shift upward, demanding White, Pink, Orange, and more Green. Now you can safely tap the central Pink and White clusters, as their matching Boxes are now active. The Surprise Bags below will start dispensing loose, single marbles in various colors, including Yellow, Orange, Blue, and Pink.

The main trap is that the center of the top tray holds colors that are not requested initially. If you tap them early, they drop onto the belt and occupy space needed for the essential Green and Purple marbles. This causes a jam that forces a restart. The key is to clear the outer and mid-flank clusters first, which unblocks the Tunnels' exits and exposes the lowest Surprise Bags, allowing you to handle the loose marbles systematically.

How to Beat Marble Sort Level 507 — Step-by-Step

Phase one: Clearing the front row

1. Tap the Green cluster on the far left edge, sending it into the top-left Green Box.
2. Tap the Red cluster on the far right edge, guiding it to the far-right Red Box.
3. Tap the inner-left Red cluster, feeding it into the inner-right Red Box.
4. Tap the inner-right Purple cluster, sliding it into the inner-left Purple Box.
5. Ignore the central Pink, White, and Blue clusters until their Boxes are active.

Phase two: Handling the Surprise Bag release

1. Tap the central Pink cluster now that the matching Box is available.
2. Tap the central White cluster, as its Box is also open.
3. Watch the Surprise Bags drop loose marbles; immediately match them to active Boxes.
4. Prioritize pulling down upper clusters that match the loose marbles to free space.
5. Never pull from a Tunnel unless the matching Box is visible on the top row of the lower grid.

Phase three: Finishing the Tunnels

1. Focus on the deep Purple and Orange stacks that cycle up from columns two and four.
2. Use the Conveyor Belt to hold one off-color cluster at a time, but store no more than two.
3. Clear Orange and Pink Boxes to reveal the final White and Green Boxes at the bottom.
4. Empty the remaining clusters from the top corners to complete the level.

Tips & tricks

• Always clear the outer edges before touching the center; this prevents early belt congestion.
• When Surprise Bags spill loose marbles, immediately find their matching Boxes to avoid accumulation.
• Limit temporary storage on the belt to two marbles max; three will likely cause a jam.
• Watch the lower grid's top row after each clear; it tells you which colors are safe to drop.

Common mistakes

• Tapping the central Pink, White, or Blue clusters before their Boxes appear is the most frequent error.
• Pulling from a Tunnel when its matching Box is not on the top row leads to overflow.
• Storing more than two loose marbles on the belt blocks the Tunnels' exits.
