Marble Sort Level 577 is a two-stage vault puzzle: a massive 13-clear Panel blocks the top back, and a 4-clear gear sits below it. The key is to break the gear first with quick matches from the left-center column, then survive the midgame clog by keeping the Conveyor Belt empty.
The board has four bottom Box columns. Left column: Green, Dark Green, Pink, Dark Green. Second column: three Light Blue stacked, then Red. Third: White, Pink, Light Green, Blue. Right column: Red, Green, Yellow, Yellow. The top tray holds bumpy Pink, Light Green, Dark Green, plus striped side boxes and later Brown and Purple.
Marble Sort Level 577 Walkthrough
Front row bottom demands: Column 1 needs Green first, Column 2 needs Light Blue, Column 3 needs White, Column 4 needs Red. But the trap is the White bottom Box—its marbles sit high and clicking them early jams the belt.
The imbalance: the left side (Light Blue) is safe to clear, but the right side (White) is a decoy. Focus on the second column to hit the four clears fast.
How to Beat Marble Sort Level 577 — Step-by-Step
Phase one: Break the gear
- Tap the Light Blue marbles from the left of the top tray to start filling the second column.
- Clear the Green from the top-left area into Column 1's bottom Box.
- Drop the Red from the top-right into Column 4's bottom Box.
- After four clears, the gear unlocks, dropping the 13-Panel counter to 9.
Phase two: Midgame cleanup
- Now you can safely route the Pink, Light Green, and Dark Green bumpy boxes into Columns 1 and 3.
- Keep the belt clear as the bottom row shifts to a full line of Yellow Boxes—use the upper right Yellow marbles only when the belt has space.
- Handle the striped side boxes only when you have two empty belt slots and a matching bottom Box ready.
Phase three: Open the vault
- Push your final Green and Pink matches to reach the 13th clear, removing the giant top-center Panel.
- Once the vault opens, new Brown and Purple marbles appear—do not drop them yet.
- Wait until all Yellow and Red Boxes are gone, then clear Brown and Purple from the top down to finish.
Tips & tricks
- Always prioritize the Light Blue stack in the second column to unlock the gear quickly.
- Keep the Conveyor Belt as empty as possible, especially before the Yellow wall appears.
- Ignore the striped side boxes until the midgame; they are a trap.
Common mistakes
- Clicking White marbles too early causes a belt jam that blocks Light Blue and Green.
- Dropping Brown or Purple before Yellow and Red are gone leads to a dead board.
