Marble Sort Level 115 — Walkthrough and Solution

Marble Sort Level 115 presents a board divided by a central wall, with the top half locked behind two separate chains. The left side is secured by a Brown lock, and the right side by a Purple lock. The key to the Brown lock is Gold, resting on the far right, while the key to the Purple lock is Purple, positioned on the far left. You must swap these keys across the board to break both locks.

The layout splits into a Top Tray and a lower set of Boxes. The Top Tray's top two rows on both sides are grey Mystery Boxes, initially untappable. On the left, below the Brown lock, visible tiles include Purple on the far left edge, then Yellow, Red, and below them Blue, two Yellows, and Green. At the very bottom of that left section sit three Purple tiles. On the right, under the Purple lock, you'll find Orange, Green, Light Blue, and a Gold key on the far right edge. The bottom row on the right holds Green, Red, and two Light Pinks, with two Yellows isolated below. The lower area consists of four columns. Column one starts with Light Pink, then Green, Red, Mystery, and Yellow. Column two has Red, Mystery, two Light Pinks, and Purple. Column three starts with Purple, then Mystery, and three Yellows. Column four stacks Red, Purple, Red, and two Greens.

Focus on the front-row demands: the first column needs Light Pink, the second column needs Red, the third column needs Purple, and the fourth column needs Red. These are your immediate targets. Avoid Blue, Orange, and Green until later.

The critical insight is that the Purple key on the left unlocks the Purple lock on the right, and the Gold key on the right unlocks the Brown lock on the left. You must clear the bottom tiles to reach these keys, but the front-row Boxes need specific colors to open up space.

How to Beat Marble Sort Level 115 — Step-by-Step

Phase one: Clear the front line

1. Tap the two Light Pink tiles on the bottom row of the right side of the Top Tray. These feed the Light Pink Box at the front of column one.
2. Now tap the exposed Red tiles on the right side of the Top Tray. These go into the Red Boxes at the front of columns two and four.
3. Shift to the left side of the Top Tray and tap the three Purple tiles sitting at the very bottom. They will fill the Purple Box at the top of column three, clearing it immediately.
4. With the Purple Box gone, you reveal a Mystery Box in column three. Leave it for now.
5. The left side now shows Blue, Yellow, and Green tiles, which are now exposed.

Phase two: Unlock the cross-keys

1. On the left side, the Purple key tile is now reachable. Tap it to send it to a lower Purple Box. If none is open, clear the Red tiles from columns two and four to reveal Purple Boxes underneath.
2. Once the Purple key is used, the Purple lock on the right shatters, unlocking the Mystery Boxes above.
3. Do not tap those Mystery Boxes yet. Instead, go to the right side and clear the Green and Light Blue tiles blocking the Gold key, but only if your lower Boxes need those colors. If your Boxes need Yellow, pull Yellow tiles from the left side to keep the board moving.
4. After the path is clear, tap the Gold key tile. It will activate and break the Brown lock on the left.

Phase three: Manage blind drops

1. Now both locks are open, exposing many Mystery Boxes. Avoid them until you've cleared all visible tiles.
2. Pull the remaining visible Blue, Orange, and Light Blue tiles from the middle sections of the Top Tray. Clear everything you can see.
3. Only tap Mystery Boxes when your Conveyor Belt has at least five empty slots. Tap two from the left side, see their colors, and match them to open lower Boxes.
4. Continue tapping Mystery Boxes one at a time, checking colors, and filling the lower Boxes. Be patient; the late game is about belt space. If you tap four differently colored Mystery Boxes in a row, you'll jam the belt. Match them deliberately to finish the level.

Tips & tricks

• Always keep your Conveyor Belt as empty as possible; never tap a Mystery Box unless you have room.
• When you clear a Box, note whether the next Box in that column is a Mystery Box; plan your next moves accordingly.
• If you get stuck, use the visible tiles to fill boxes in the order they appear from left to right; this often opens new paths.

Common mistakes

• Tapping Mystery Boxes too early can flood your belt with colors you don't need yet.
• Forgetting to use the Purple key before clearing the right side can leave you blocked.
• Mixing up which key unlocks which side can cause you to waste moves.
