Marble Sort Level 159 — Walkthrough and Solution

Marble Sort Level 159 is a tricky grid that hides its true requirements behind a row of Mystery Boxes. The key is to ignore the tempting Orange marbles in the front and focus on the outer edges to drop the countdown gates fast.

The board has a top tray with five columns and a bottom area with four receiving slots. The front row shows Light Green, Dark Red, Orange, Orange, and Pink from left to right. Behind these, the second row is all Mystery Boxes, and the back rows hold more colors. The bottom slots demand Light Green, Dark Red, Dark Blue, and Light Green, but there are no Orange slots initially, making Orange a decoy.

Marble Sort Level 159 Walkthrough

At the start, the bottom receiving slots are: far-left needs Light Green, inner-left needs Dark Red, inner-right needs Dark Blue, and far-right needs Light Green. There are two Light Green slots but only one visible Light Green group in the top tray, and one Dark Red slot with one Dark Red group. The other required marbles are hidden in Mystery Boxes.

The main trap is the pair of Orange groups in the front row. Tapping them early will clog your Conveyor Belt because there are no Orange slots to catch them until later. Also, four blue countdown gates with a '2' are scattered, blocking the back columns until you clear two bottom boxes.

How to Beat Marble Sort Level 159 — Step-by-Step

Phase one: Unlock the countdown gates

1. Tap the far-left Light Green group to drop it onto the belt; it will fill both Light Green slots partially.
2. Slide the inner-left Dark Red group into its slot.
3. Resist the Orange and Pink groups for now.
4. Open the Mystery Box behind the Light Green (column one) and hope it's Light Green or Dark Red.
5. Open the Mystery Box behind the Dark Red (column two) to get matching marbles.
6. Clear the Light Green bottom box completely to expose a locked Dark Blue slot underneath.
7. Clear the Dark Red bottom box to drop the countdown gates to zero, unlocking the middle.

Phase two: Unlock the locked Dark Blue slot

1. Now that the gates are down, access the back rows of the top tray.
2. Look at the fifth column: there's a Dark Blue group behind the Pink. Release the Pink group first to reach it.
3. If the far-right Light Green box has cleared, a Pink bottom slot will appear; use it to clear the Pink.
4. Pull the Dark Blue group from column five to feed the bottom slots; this may drop the key to break the lock on the far-left Dark Blue slot.
5. Once the lock is gone, an Orange receiving box appears in the lower center. Now you can tap the two front-row Orange groups to fill it.

Phase three: Manage the belt and finish

1. Continue opening Mystery Boxes one at a time, waiting for the belt to clear before opening another.
2. Route the Light Blue and Green marbles from the deep columns to their matching bottom slots.
3. Always keep at least two empty spaces on the belt as a buffer for unexpected colors like Grey or Magenta.
4. Keep clearing boxes until all slots are filled and the level is complete.

Tips & tricks
