Marble Sort Level 246 Walkthrough & Solution

Level 246 Board Overview: The Mystery-Sealed Tray

Level 246 opens as a hard mystery-box board, and the first thing you notice is how much of it you cannot see. The upper grid is packed with grey ’?’ mystery tiles — the two outer columns are sealed from top to bottom, and scattered ’?’ tiles cap the rest of the stacks. Only a handful of colors are honest at the start: Dark Blue, Orange, and Red sit visible in the grid alongside White and Dark Purple, with a few Yellow tiles already riding the conveyor below.

The receiver Boxes at the top open the level asking for Dark Blue, Orange, and Red, with a second wave of Orange and Purple waiting just below. Behind those sit Dark Purple and White receivers — colors that only matter once the front row cycles. The conveyor is stocked from the first moment, feeding tiles up toward the grid as you clear space.

The middle of the board is where the danger lives. Purple tiles keep appearing as mystery tiles reveal — some hollow, some solid — and they show up long before any Purple receiver is active. Nothing about the opening tray is a straight line: reveal the ’?’ tiles, feed the open colors, and wait for the receivers to rotate toward everything you just freed.

The Trap in Marble Sort Level 246

The board is rigged to make you reveal faster than you can sort. Here is the layout:

• The outer columns are fully sealed: the far-left and far-right stacks are nothing but grey ’?’ mystery tiles from top to bottom. You cannot plan around them until you tap them, so every early reveal is a gamble.
• Purple has no receiver at the start: Purple tiles sit hollow and solid across the grid, but the opening Boxes ask for Dark Blue, Orange, and Red. Feed Purple early and the conveyor jams before the front row clears.
• The conveyor is preloaded with mixed colors: Yellow, Red, and mystery tiles ride the belt from the first frame. A queue tile is only safe when its color matches an open Box.
• Receivers sit in staggered rows: Dark Blue, Orange, and Red open the level, but Orange and Purple wait in the row behind, and Dark Purple and White linger at the back. Colors you touch too soon become permanent belt passengers.

Marble Sort Level 246 Step-by-Step Walkthrough

Reveal the board before you commit to it. Follow the release order.

Opening: feed only the honest colors

1. Tap the visible Dark Blue tiles straight into the Dark Blue Box. This is the safest drop on the opening board.
2. Feed the Orange tiles into the Orange receiver next — Orange has both a front-row Box and another waiting in the second row, so it is never wasted.
3. Drop the Red tiles into the Red Box as they surface. Red stays useful through the whole opening.
4. Start peeling the ’?’ mystery tiles off the column tops. If the reveal matches an open Box, drop it; if not, leave the column and come back.
5. Treat every revealed Purple as bait — no Purple Box exists yet, so do not park it on the belt.
6. Keep the conveyor fed with Dark Blue, Orange, and Red only. Let Yellow and White tiles pass on the belt until their receivers cycle forward.

Midgame: let the receivers rotate toward the tray

By the middle of the solve the grid has thinned out and the front row has cycled hard — the Boxes now ask for Red, Yellow, Brown, Orange, Green, and Pink. The remaining columns hold Purple, Red, Orange, Pink, and Green, and the conveyor is running mixed batches of Green, Yellow, Cyan, Light Blue, Medium Blue, and Dark Blue.

7. The moment the Yellow Box opens, clear every Yellow you have been letting ride the belt — they finally have a home.
8. Feed Brown as soon as its Box slides to the front. Brown barely appears on the board, so its receiver fills from the conveyor batches.
9. Work each mystery-capped column down one tile at a time. The Purple tiles buried in the stacks are your real constraint: they cluster in pairs, so clear them in runs when their Box finally appears.
10. Prioritize columns that expose two matching tiles in a row — clearing them empties a column and opens the tray.
11. Take the conveyor in its batches: Green, Yellow, and the light blues feed neatly into the new receivers, so a full matching batch finishes a Box in a single pass.
12. When a ’?’ tile rides the belt, treat it as an unknown: only play it when its color matches the front Box, and never stack a combo on top of it.

Cleanup: feed the stragglers

The end frame catches the level still mid-solve: the tray is stripped down to scattered Green, Pink, Light Blue, and Purple tiles, while the queue runs Blue, Cyan, Yellow, Brown, and Orange with a red cluster waiting above. It is a straight finishing line from here.

13. Every remaining tile is a single waiting for its Box to slide to the front — play only to the active front row.
14. Let the queue cycle: the last Greens, Pinks, and Light Blues feed as their receivers open. Do not chase colors whose Boxes have already closed.
15. Finish the final receivers as the stragglers drop and let the tray empty. The level completes the moment the last tile lands.

Level 246 Tips Recap

• Reveal before you commit: every column opens under a ’?’ tile, so never plan a combo on colors you cannot see.
• Only feed colors with an open Box — Dark Blue, Orange, and Red open the level; Purple is bait until the midgame receivers rotate.
• Purple is the whole level: it hides under mystery tiles, arrives in pairs, and jams the belt if you touch it early.
• In the endgame the tray is nearly empty; just cycle the belt and feed the last singles into their receivers.
