Marble Sort Level 315 — Walkthrough and Solution

Blue → Pink. The top layer hides what's underneath.

Marble Sort Level 315 presents a deceptive board where the front row tempts you with textured Pink and Yellow boxes, but tapping them early will clog the Conveyor Belt. The winning strategy is to focus on the bottom Boxes' initial demands: Blue, Purple, Red, and Purple, in that order, before touching the front-row colors.

The Top Tray's front row holds a Pink, a Yellow, another Pink, a Yellow, a Blue, a Pink, and a Red from left to right. Behind them, a second row contains Purple, Blue, Pink, Red, Pink, Blue, and Yellow. The bottom receiver Boxes initially require Blue in column one, Purple in column two, Red in column three, and Purple in column four. The lower Boxes hide deeper stacks of Pink, Yellow, Green, and Blue. The middle section has linked tiles that drop together, and the sides have Arrow Boxes pointing inward. Three Tunnels (top center, middle-left, middle-right) each hold four extra boxes, ready to flood the board if space is cleared prematurely.

Marble Sort Level 315 Walkthrough

The front-row demands are Blue, Purple, Red, and Purple across the four columns. The left side of the front row is packed with Pinks and Yellows, but they are not yet accepted by the bottom Boxes. The lower Boxes have deep stacks of Pink, Yellow, Green, and Blue, but those are only reachable after the initial blockers are cleared.

The critical trap is that the front-left Pinks and Yellows are bait. If you drop them early, they will fill the Conveyor Belt with useless colors while the bottom Boxes still need Blue, Purple, and Red. The Tunnels will then add more boxes, causing a jam.

How to Beat Marble Sort Level 315 — Step-by-Step

Phase one: Clear the initial blockers

  1. Tap the textured Blue box on the front-right side of the Top Tray to match the Blue Box in column one.
  2. Tap the textured Red box on the front-right to match the Red Box in column three.
  3. Extract Purple boxes from the second row, using at most one front Pink as a temporary hold on the Conveyor Belt if needed, to fill the Purple receivers in columns two and four.
  4. Once the Blue, Purple, Red, and Purple receivers are filled, the bottom Boxes will reveal Pink and Yellow slots.
  5. Now unload the front-row Pink and Yellow boxes into those newly opened slots.

Phase two: Unlock the Arrow Boxes

  1. Clear the center vertical column, which contains Red, Green, and Pink, by matching them to the appropriate bottom Boxes.
  2. When moving linked tiles, ensure at least one of their colors has an open receiver to avoid using multiple Conveyor Belt slots.
  3. As the center empties, the left Arrow Boxes (Yellow, Green, Pink) and right Arrow Boxes (Green, Blue, Green) will activate, pushing marbles toward the center.
  4. Quickly guide the Arrow Boxes' colors into the lower Boxes to prevent accumulation.

Phase three: Drain the Tunnels

  1. Clear the tiles directly in front of the three Tunnels to allow them to release their four boxes each.
  2. Let the Tunnels discharge, and then sort the output carefully, focusing on matching deep Blue and Green receivers that surface at the bottom columns.
  3. If a Tunnel releases an unneeded color, leave it in the Top Tray and prioritize clearing the deep colors to secure the win.

Tips & tricks

  • Always check the bottom Boxes' current requirements before making a move; they change as you clear layers.
  • Keep the Conveyor Belt as empty as possible, especially before activating Tunnels.
  • Use the Arrow Boxes to your advantage by matching their colors immediately when they slide into play.

Common mistakes

  • Dropping front-row Pink and Yellow boxes too early, causing a Conveyor Belt jam.
  • Ignoring the order of colors the bottom Boxes demand, leading to mismatched drops.
  • Activating Tunnels before clearing space, resulting in a flood of boxes.
