Marble Sort Level 413 — Walkthrough and Solution

Marble Sort Level 413 presents a board where the middle is sealed by a lock mechanism, forcing you to work around the edges. The key to victory is to first extract the golden key from the top-left area, which will unlock the center and flood the board with new colors. Prepare for a routing challenge where early mistakes can jam your conveyor belt and halt progress.

The top tray is divided into sections. The three middle columns are covered by a chain, hiding Brown, Purple, and Green marbles that are inaccessible until the lock breaks. The key rests on a Dark Blue marble in the far top-left corner. Above it, a column of arrow marbles includes Light Blue, Green, Purple, and White from top to bottom. On the right side, a stack with Orange and Purple marbles sits above Black and Pink ones. The bottom boxes initially ask for White, Black, Green, and Black from left to right. Light Blue marbles are plentiful near the bottom of the tray, but they are a trap because no starting box needs them.

Marble Sort Level 413 Walkthrough

The front row of boxes demands White, Black, Green, and Black from left to right. These colors are partially buried under obstacles, so you must carefully route marbles from the outer columns.

The critical imbalance is that the key is hidden under Light Blue and Green marbles on the left, while the starting boxes want Black and White. If you waste belt space on Light Blue early, you will run out of room before unlocking the center.

How to Beat Marble Sort Level 413 — Step-by-Step

Phase one: Unlock the Center

1. Tap the White marble from the bottom center of the top tray to fill the leftmost White box.
2. Clear the Black marbles that are easy to reach from the bottom right side.
3. When a Green box appears, pull the Green arrow marble from the left column to clear it.
4. Continue stripping the left column: feed Purple and White marbles into matching boxes as they cycle.
5. Leave the Orange marbles on the right alone unless an Orange box blocks progress.
6. After clearing the top White marble, the Dark Blue marble becomes visible. Drop it into a Dark Blue box to send the key to the lock and break it.

Phase two: Manage the Center Flood

1. Once the lock shatters, the middle columns drop, revealing Brown, Light Blue, Purple, and Orange marbles.
2. Pause and check the new bottom boxes; they likely now need Orange, Purple, and Pink.
3. Clear the Orange marbles from the top right into Orange boxes to lower that side.
4. Do not pull Light Blue marbles from the large cluster in the lower-middle until two Light Blue boxes are active.
5. Feed the Brown marbles from the middle-left column into boxes as they appear.
6. Keep an eye on belt space; avoid tapping deep center colors unless a matching box is ready.

Phase three: Final Cleanup

1. Remove the remaining Purple and Pink marbles from the lower rows.
2. Clear the last Dark Blue and Black marbles from the top of the right columns.
3. Match remaining colors in an orderly fashion to finish the level.

Tips & tricks

• Always prioritize emptying the left column to reach the key quickly.
• Ignore Light Blue marbles until the center is open and boxes require them.
• Keep the conveyor belt as empty as possible by only tapping marbles that have a matching box.

Common mistakes

• Dumping Light Blue marbles early can jam the belt and block progress.
• Getting distracted by the right side before the key is collected wastes moves.
• Rapid tapping after the unlock can lead to unmatched marbles and a full belt.
