Marble Sort Level 120 — Walkthrough and Solution

Marble Sort Level 120 presents a board dominated by a gray center that hides two tunnels with counters starting at 4. The outer edges of the top tray hold Dark Red, Light Blue, Pink, and Yellow, but they are not all immediately useful. The key is to follow a strict sequence: clear the first four bottom boxes in the order Dark Red, Yellow, Pink, Light Blue, which will drop the tunnel counters to zero and shatter the gray shell.

The top tray is arranged with a dead zone in the middle. On the left flank, you see Yellow, White, and Light Green clusters. The right flank has Pink, Orange, and Light Blue. The top ridge contains Light Blue, White, and Dark Blue. The bottom lip offers Light Pink, Dark Red, and Dark Blue. The bottom area has four columns. From left to right, column one demands Dark Red, Dark Red, Dark Blue, White, then Pink. Column two stacks Light Blue, Pink, Dark Blue, Dark Red, and Light Blue. Column three lines up Pink, Light Blue, Light Green, Light Blue. Column four starts with Yellow, then Purple, then a hidden Mystery Box, and ends with Purple. The Light Pink and Dark Blue clusters on the bottom lip are decoys; they lack corresponding front boxes and will clog the belt if taken early.

Marble Sort Level 120 Walkthrough

The front row of bottom boxes, from left to right, asks for Dark Red, Light Blue, Pink, and Yellow. These must be fed using only the exposed edges of the top tray. The trap is that Light Pink and Dark Blue are tempting but not yet needed, and the hidden Mystery Box in column four makes it impossible to plan for the far right without clearing it.

The board forces you to play from the outside in. The gray wall in the center blocks access to the tunnels until enough bottom boxes are cleared. The limited space on the conveyor belt means you cannot afford to grab colors randomly; every move must be deliberate.

How to Beat Marble Sort Level 120 — Step-by-Step

Phase one: Clear the front row

1. Tap the Dark Red cluster at the bottom center lip to feed the first column's front box.
2. Slide the Yellow cluster from the far left edge to clear the fourth column's front box.
3. Drop the Pink cluster on the far right edge to fill the third column's front box.
4. Send the Light Blue from the top right edge to satisfy the second column's front box.
5. Stop touching the perimeter. Leave White, Light Green, and Dark Blue alone for now.

Phase two: Unlock the tunnels

1. Watch the counters on both tunnels drop to zero after the first four clears. The gray shell will shatter.
2. Release Orange from the right tunnel only when an Orange box is exposed or you have belt space.
3. Keep Dark Blue from the left tunnel parked until a Dark Blue box appears in column one or two.
4. Now feed the second layer: Dark Red into column one, Pink into column two.
5. Clear the Purple box in column four to reveal the Mystery Box behind it.

Phase three: Manage the late game

1. Reserve belt space for transition colors. Avoid pulling Light Green, Green, and Purple simultaneously.
2. Prioritize any front box that blocks a Mystery Box, as those hidden targets dictate future moves.
3. Match the Orange from the right tunnel into newly exposed lower slots.
4. Delay Light Pink and White until their corresponding boxes appear at the back of the columns.

Tips & tricks

• Clear the front row in the exact order: Dark Red, Yellow, Pink, Light Blue. This drops the tunnel counters efficiently.
• Keep the conveyor belt as empty as possible, especially during the middle phase when Orange and Dark Blue are released.
• Use the Mystery Boxes as guides; they reveal which colors are safe to drop next.

Common mistakes

• Tapping Light Pink or Dark Blue early, which clogs the belt and jams the board.
• Releasing Orange or Dark Blue from the tunnels before their boxes are exposed.
• Ignoring the Mystery Box in column four, leaving the right side blocked.
