Marble Sort Level 174 — Walkthrough and Solution

Marble Sort Level 174 is a puzzle where a 7x7 top grid hides a large yellow structure in the middle, and four bottom columns are stacked five containers deep. The winning approach is to clear the front containers from left to right exactly as they appear, ignoring the tempting exposed marbles on the lower row of the top grid until later.

The top grid has two useful side columns: the far left holds Purple, Orange, White, and Green; the far right holds Red, White, Blue, and Yellow. The bottom row of the top grid shows, from left to right: Purple, White, Orange, Green, Dark Red, Blue, and Light Blue. The four bottom columns start with these front colors: Column 1 has Purple on top; Column 2 has Purple on top; Column 3 has Red on top; Column 4 has Orange on top. Underneath these fronts, the columns hide deeper colors: Column 1 hides Red, then a Mystery Box, then Yellow, then Green; Column 2 hides Light Blue, then Pink, then Blue, then Purple; Column 3 hides White, then Red, then Purple, then Green; Column 4 hides Red, then Orange, then Purple, then Pink.

Marble Sort Level 174 Walkthrough

The bottom columns' front demands are clear: two Purple containers, one Red, and one Orange. If you pull any other color from the top grid's bottom row early, that marble will sit on your Conveyor Belt and block your moves, so you must stick to the needed colors.

The specific trap is that the exposed White and Green clusters on the top grid's bottom row look safe but are not needed early; pulling them fills your belt with colors that have no matching open container, causing a jam.

How to Beat Marble Sort Level 174 — Step-by-Step

Phase one: Clear the front line

1. Tap the Purple marble at the far left of the bottom row on the top grid; this goes into the first Purple container.
2. Next, find Purple in the upper left column of the top grid and tap those to fill the second Purple container in Column 2.
3. Now locate the Orange cluster in the third position from the left on the bottom row of the top grid; tap it to fill the Orange container in Column 4.
4. Look to the right side of the top grid to find Red marbles; tap them to fill the Red container in Column 3.
5. Do not tap the White or Green clusters on the bottom row; leave them untouched for now.

Phase two: Handle the new front row

1. After clearing the first front row, the new front containers appear: they need Light Blue, Brown/Red, Blue, and another Brown/Red. Tap the Light Blue cluster from the bottom right corner of the top grid to fill that container.
2. Next, find the Blue cluster on the bottom right area of the top grid and tap it to fill the Blue container in Column 3.
3. Now you need to fill the two Brown/Red containers in Columns 2 and 4. Search the top right and top center of the grid for these dark rusty red marbles and tap them.
4. While you do this, watch your Conveyor Belt. If any Orange, Purple, White, or Green marbles from earlier are still on it, you are in danger; only pull a color when you can complete a full set of three to clear a bottom container immediately.
5. As you clear the outer edges, the yellow bars in the center will start to lose support. Begin tapping the colors directly under those yellow rings (like Green and Blue in the middle) to break the structure apart.

Phase three: Reveal the Mystery Boxes

1. Now you will uncover Mystery Boxes in Columns 2 and 3. Tap a single marble into a Mystery Box to reveal its true color. Do not dump three marbles until you know what color it needs.
2. After the center yellow bars are gone, you will see a cluster of Pink marbles in the top left and scattered Yellows. Use the extra space on your Conveyor Belt to hold one or two stray colors while you dig through the top grid to find the colors needed by the revealed Mystery Boxes.
3. Finish by clearing the remaining Pink and Yellow clusters into the last bottom containers. Keep your focus on the active front row and never pull a color that isn't needed.

Tips & tricks

• Always clean your Conveyor Belt before pulling a new color; a full belt is a game over.
• Use the side columns of the top grid as your main source for early colors, not the bottom row.
• When you see a Mystery Box, reveal it with one marble first, then match the revealed color.

Common mistakes

• Tapping the White or Green clusters on the bottom row too early, which clogs your belt.
• Ignoring the front row order and pulling colors randomly, causing mismatches.
• Dumping three marbles into a Mystery Box before revealing it, which can waste moves.
