Marble Sort Level 57 — Walkthrough and Solution

Marble Sort Level 57 makes the obvious tap the wrong one. Bright greens, pinks, and light blues pack the tray, and three white blocks sit across the middle of the front line with nothing to catch them. Three Tunnels stamped 3 hide through the centre and edges, and four Arrow Boxes point at columns you cannot touch yet.

The Top Tray opens with a flat bottom row — dark green on the far left, a solid strip of three whites in the middle, then dark blue and pink on the right. Just above, the board tightens with a pink arrow pointing left, a dark green arrow pointing up, and a second pink arrow pointing left.

Marble Sort Level 57 Walkthrough

The bottom Boxes are deliberately out of step with the front line. The front row wants dark green, light blue, pink, and lime green, but the centre hands you three white blocks with no White Box anywhere in view. Those whites are the trap — shift them early and they idle on the belt, choking your workspace before the first Tunnel opens.

Higher up, three Tunnels — a mix of light and dark blue — each stash three blocks, and you cannot know what they release until you clear beneath them. The entire opening is about ignoring the centre and working the corners.

How to Beat Marble Sort Level 57 — Step-by-Step

Beat the white bait

1. Begin on the outside. Send the dark green marbles from the far-left corner down into the dark green Box sitting in the far-right front row.
2. That clear uncovers a dark blue Box just under it, so feed the dark blue marbles from the bottom-right into it.
3. Then route the pink marbles on the bottom-right into the pink Box waiting in the middle-left slot.
4. The board shifts once those go, and now white Boxes appear in the second row — so send the three white blocks down to finish the front line.

Unlock the Arrow Boxes

1. Find the pink arrow on the right that points left, and clear the light blue block in its path so it can fire.
2. Work on opening the Tunnels by pulling pieces from the columns below them, which hands fresh marbles into the Top Tray.
3. Keep one eye on the belt — the Tunnels tend to release a jumble of light blue and purple, so only pull from a Tunnel column when a matching Box is open.
4. The middle-right slot holds a light blue Box that guards three bright green Boxes, so clear the light blue drops to reach those greens.

Survive the final Tunnel drop

1. A green arrow lurks in the top-left corner, pointing right, so clear the space beside it before it can move.
2. The Tunnels wind down from 3 to 1, and their last loads push a wave of purple and pink into the Top Tray.
3. Read the bottom rows often — a long vertical run of Purple Boxes waits on the middle-left, so feed purple down rather than letting it rest.
4. Drain the Tunnels one by one, clear the purple chain on the left, then sweep right to close it out.

Tips & tricks

• Leave the three white blocks alone until the second row shows White Boxes. Moving them early strands them on the belt.
• Clear the dark green, then the dark blue, then the pink — that flank order exposes the White Boxes that unlock the centre.
• Drain the Tunnels one at a time, because triggering all three dumps a mixed rainbow you cannot sort fast enough.

Common mistakes

• Tapping the three white blocks in the opening. They have no White Box waiting up front, so they rot on the belt and choke the workspace.
• Pulling all three Tunnels at once. Their purple and pink payloads collide on the belt and jam it before you can clear either chain.
