Marble Sort Level 222 — Walkthrough and Solution

This puzzle presents a T-shaped upper tray with a row of grey Mystery Boxes hiding behind the visible front layers. On the far left and right, numbered blue Tunnels hold reserve boxes that slide in as space opens. The bottom section is a grid of Boxes, each holding three marbles, and the upper boxes each release nine marbles, so one upper box demands three lower Boxes to fully empty. The level is won by following a specific clearing order, not by tapping everything in sight.

The layout of Marble Sort Level 222 places three fully loaded upper boxes in the front row: Light Blue on the left, Brown in the middle, and Yellow on the right. Behind them sit Light Green, Pink, and Dark Green, with grey Mystery Boxes filling the rest of the upper tray. The bottom Boxes are arranged in columns, with the first two columns initially needing Light Blue, the third Light Green, and the fourth Pink. Deeper rows hide Dark Green, Brown, and Yellow targets, while the side Tunnels release additional boxes as the board clears.

Marble Sort Level 222 Walkthrough

The initial bottom Boxes demand Light Blue in columns one and two, Light Green in column three, and Pink in column four. The front Brown and Yellow upper boxes have no matching bottom Boxes in the early rows, so tapping them early would fill the Conveyor Belt with unusable marbles. The correct order is to first clear the Light Blue box on the front left, then the Pink box from the second row, then the Light Green box, and only later address the Dark Green, Brown, and Yellow boxes as their targets appear.

The critical danger is that releasing a full upper box fills three bottom Boxes but also strands three marbles on the Conveyor Belt, because each bottom Box only holds three. Since the next matching bottom Box is often buried several rows down, you must accept some early belt congestion but avoid making it worse by tapping colors that have no target at all. The key is to clear the three colors that have immediate targets first, then use the newly exposed Mystery Boxes to free the belt.

How to Beat Marble Sort Level 222 — Step-by-Step

Phase one: Clear the opening colors

1. Tap the Light Blue upper box on the front left. Nine marbles drop; six fill the first two bottom Boxes, and three remain on the Conveyor Belt.
2. Do not tap the front Brown or Yellow boxes; they are decoys with no current targets.
3. After the first clear, column one now needs Pink, and column two needs Light Green.
4. Tap the Pink upper box from the second row. Nine Pink marbles drop; three fill column one, three fill the Pink bottom Box in column four, and three join the Light Blue on the belt.
5. Tap the Light Green upper box. Three go to column two, three go to column three, and three get stuck on the belt.
6. Now your Conveyor Belt holds three Light Blue, three Pink, and three Light Green marbles, which is near its capacity.

Phase two: Unlock the Mystery Boxes

1. With the front upper boxes cleared, the second and third layers of bottom Boxes are exposed, revealing Dark Green targets in columns two and four.
2. Tap the Dark Green upper box from the right side. This clears those targets and prevents the belt from jamming completely.
3. As the front row of the upper tray thins, the grey Mystery Boxes reveal their true colors, and the side Tunnels begin to drop new boxes into play.
4. Your immediate goal is to free the Conveyor Belt by finding bottom Boxes that need Light Blue, Pink, or Light Green. As soon as you uncover one, it will automatically absorb the stranded marbles, opening up space.

Phase three: Late game cleanup

1. Continue working through the newly revealed Mystery Boxes, only releasing colors that have an available bottom Box.
2. Dig down to the third row of the bottom section to expose the Brown targets in columns one and four.
3. Now you can safely tap the starting Brown box that has been waiting in the front of the upper tray.
4. Dig down to the fifth row to reveal the Yellow targets, then clear the starting Yellow box to fully open the board.
5. Let the side Tunnels empty out, matching the remaining marbles back-to-front, and finish clearing the staggered bottom columns.

Tips & tricks

• Always check the bottom Boxes before tapping an upper box; only release a color if you see a matching empty or partially filled bottom Box.
• Keep the Conveyor Belt as empty as possible; avoid tapping colors like Brown or Yellow early because they have no targets for a long time.
• Use the side Tunnels to your advantage: they bring new boxes that can match the marbles stuck on your belt.

Common mistakes

• Tapping the front Brown or Yellow boxes too early, which floods the belt with marbles that cannot be cleared.
• Ignoring the Conveyor Belt capacity and releasing too many colors at once, causing a jam.
• Not checking the bottom row requirements before each tap, leading to missed opportunities to clear the belt.
