Marble Sort Level 88 locks the middle behind a 32-clear Panel and a double Lock-and-Key setup. You're forced to play the narrow side columns while the center stays dead. The dominant colours are Black, Blue, White, Dark Green and Bright Green, and the top-corner Dark Greens are the purest bait on the board.
Down the left column sit Bright Green, Blue, Dark Green, White, an Orange box, and Pink holding the Yellow Key. The right column runs Black, Dark Green, Cyan, Orange carrying the Purple Key, another Black, then a Purple box. The bottom Boxes want Bright Green, Black and two Purples first, then White, Pink, Black and Cyan.
Marble Sort Level 88 Walkthrough
The Dark Greens at the top corners have no Box in the early sequence, so pulling them sits on the belt and rots. Every tap has to serve the front row directly. The two keys — the Purple Key on the right and the Yellow Key on the left — are your midgame targets, and clearing them shatters the chains.
Work bottom-up, match the visible Boxes exactly, and let the 32 count tick down as you sort.
How to Beat Marble Sort Level 88 — Step-by-Step
Avoid the side-column bait
- Pull the Bright Green from the left column to clear the first bottom Box.
- Drop the lower Black from the right column for the second Box.
- Hands off the Dark Greens at the top of both columns.
- Pull the White from the left column once the White Box slides forward.
- Drop the Pink block (Yellow Key) when the Pink Box reaches the front, then the Cyan and Orange block (Purple Key) on the right.
Break the locks and Panel
- Drop the Orange block into an Orange Box to smash the Purple Lock, and the Pink block into a Pink Box to smash the Yellow Lock.
- The center opens to Purple, Light Blue, Blue, White and Pink — pull from it to fill the waiting Blue and White Boxes.
- Keep the belt clean and let Brown and Bright Green Boxes cycle forward.
Survive the final colour flood
- Pull the Brown marbles from the center for the mid-game Brown Boxes.
- Drop the textured Orange and Purple boxes at the bottom of the columns only when their colours reach the front.
- Flush the Dark Greens at the very end, when their Boxes finally appear.
Tips & tricks
- The top-corner Dark Greens are bait until the very end — their Boxes don't exist early.
- Clear the Pink and Orange blocks to grab both keys and shatter the chains.
- Work each side column bottom-up and never pull a colour without a front-row Box.
Common mistakes
- Pulling the top-corner Dark Greens in the opening. They have no Box and sit on the belt for the whole mid-game.
- Forcing pulls to lower the 32 count instead of serving the front row, jamming the belt.
