Marble Sort Level 82 chains the top half of the board shut and dangles a golden key just out of reach. That key perches at the top of a thin, cut-off chute on the far left, five layers deep. Rush that left side and your belt jams in seconds.
The left chute holds the key, with two brown blocks, a pink block and an orange block beneath it. The main right grid has a chain across its upper rows, and below it sits brown, dark green, purple, red and light blue. Almost every bottom Box is light blue, with a single dark green thrown in — and not one brown on the front line.
Marble Sort Level 82 Walkthrough
The brown blocks near the chute's base are the biggest trap on the board. Their Boxes aren't up front, so digging for the key early fills the belt with brown and chokes you instantly. Knock out the front Boxes and let the rest of the board come to you instead.
Wait for the brown Box to surface, and only then start digging the left chute toward the key.
How to Beat Marble Sort Level 82 — Step-by-Step
Survive the opening bait
- Tap the light blue and dark green blocks along the bottom of the main grid to feed the front Boxes.
- Ignore the left chute completely — leave the brown blocks where they are.
- Clear the secondary pink and green Boxes as they slide forward, pulling from the main grid.
- Wait for a brown Box to surface at the front — that's your green light.
- Only now tap the left side's brown blocks to open the path without jamming the belt.
Break the lock and clear the main board
- Match the pink block in the chute to a pink Box, then the orange block, dropping the golden key.
- When the chain shatters, a big cluster of bright green becomes available — match it to the green Boxes fast but don't blind-tap.
- Hold the red and purple in the middle — their Boxes aren't ready yet.
- Peel away the top-right light blue and pink clusters to open vertical space.
Manage the late-game colour surge
- White and orange Boxes slide forward — hold the white block on the far right until its Box is at the front.
- Keep the belt empty as you pull the final red, orange and purple one by one.
- Only touch the Tray once the exact matching Box is visible at the front.
Tips & tricks
- Don't dig the left chute until a brown Box is actually at the front.
- The key drops when you clear the orange block, so pace the pink first.
- Hold the white block on the far right until its Box is visible.
Common mistakes
- Digging the left chute for the key before the brown Box appears, flooding the belt with brown.
- Blind-tapping the green flood when the chain breaks and dropping greens with no home.
