Marble Sort Level 216 — Walkthrough and Solution

Marble Sort Level 216 is a board where the top half is sealed off by two locks, and the keys to those locks are swapped. On the left, a Purple key sits on a Light Pink box, while on the right, a Brown key is on a Red box. You must clear those boxes to shatter the chains, but you have to do it while managing a crowded Conveyor Belt and a wall of Mystery Boxes in the middle.

The upper area holds a Top Tray with a Dark Blue box and a Cyan box at the front, and behind them a row with Purple, Dark Grey, Orange, and Red. The lower Boxes at the start ask for Light Blue, Dark Blue, and Orange. The sides have Arrow Boxes, but they are not your first move. The center is a cross of Mystery Boxes that hide unknown colors.

Marble Sort Level 216 Walkthrough

At the bottom, your first targets are a Dark Blue lower Box and an Orange lower Box on the right. Feed them immediately to cycle the board. The left side of the Conveyor Belt will fill up with spare colors, but that is unavoidable. You must dig down to reach the key boxes.

The trap is that the Purple Key is on the left, but the Brown Key is on the right, so you have to work crosswise. If you start clearing the center Mystery Boxes too early, you will jam your belt. Instead, focus on the lower targets and the key boxes only.

How to Beat Marble Sort Level 216 — Step-by-Step

Phase one: Unlock the left chain

1. Tap the Dark Blue box at the bottom center of the Top Tray to feed your Dark Blue lower Box.
2. Drop the Cyan box next to it onto the Conveyor Belt; you need to move it aside to reach the row behind it.
3. Tap the Orange box you just uncovered to fill the Orange lower Box.
4. After the Orange target clears, new lower Boxes appear. Look for a Red target or a Light Pink target.
5. When a Red target shows up, tap the Red box on the right side of the Top Tray. That box holds the Brown Key, and clearing it breaks the Brown Lock on the top left.

Phase two: Unlock the right chain

1. Now find a Light Pink target in the lower Boxes. If it is not there yet, clear other lower targets until it cycles in.
2. Tap the Light Pink box on the left side of the Top Tray to break the Purple Lock on the top right.
3. Now both locks are gone, so the upper corners are accessible.
4. Start clearing the Arrow Boxes only when their matching lower targets are visible. For example, the down-pointing Light Blue Arrow Box is safe once a Light Blue target appears.
5. Peel back the central Mystery Boxes one at a time. Tap one, see its color, and if you have a matching lower Box, clear it; otherwise, leave it and wait.

Phase three: Clear the top corners

1. The two Panels at the top have a countdown of 2. By clearing the key boxes and the front line, both Panels will vanish, revealing the top corners.
2. Those corners hide heavy colors like Brown and Green. Do not drop them until your Conveyor Belt is relatively empty.
3. Wait for the lower Boxes to cycle and let the loose marbles on your belt sort themselves into new targets.
4. Once the belt is clear, drop the top corner boxes to finish the remaining targets and clear the board.

Tips & tricks

• Keep an eye on the lower Boxes; they dictate your moves. Only clear a box when its color is requested.
• When you tap a Mystery Box, do not tap another one until the revealed marble is placed or you have a place for it.
• Use the Conveyor Belt as a temporary holding area, but do not let it get too full. If it jams, you are forced to waste moves.

Common mistakes

• Do not clear the Arrow Boxes too early; they are decoys that fill your belt with useless colors.
• Do not attack the center Mystery Boxes blindly; you will jam your belt and run out of space.
