Marble Sort Level 10 Walkthrough: Tunnel & Pink Bait

Level 10 Board Overview: One Pink Too Many

Level 10 is a patience exam. The Top Tray is a jagged, staggered grid with a chunk missing on the left and a heavy stack on the right, where a Tunnel tile showing a countdown of 3 plugs the bottom-right corner. Light Blue, Pink, Dark Blue, Yellow, and Orange are the colors in play.

Along the tray’s bottom edge you can reach four blocks: Pink on the left, Dark Blue in the middle, a second Pink, and a Light Blue pinned under the Tunnel. Orange, Yellow, and more Light Blue are stacked behind them, untouchable for now.

The receiver Boxes below run four columns wide and four deep, and the front row asks for Dark Blue, Pink, Dark Blue, and Light Blue. Sounds generous — until you count what the tray is actually holding.

The Trap in Marble Sort Level 10

The bait is in the mismatch between supply and demand:

• Two Pink blocks in reach, one Pink Box open. Tap both and the second Pink lands on the Conveyor Belt with nowhere to go, eating your most limited resource.
• Two Dark Blue Boxes open, one Dark Blue block in reach. The matching second Dark Blue is buried directly behind the front line — you have to earn it.
• The Tunnel guards the Light Blue. Pulling the block under it ticks the counter from 3 to 2, which you need — and it only works because column 4 happens to want Light Blue right now.

Every opening tap has exactly one correct answer. Freestyle it and the belt clogs before the second row of Boxes ever slides forward.

Marble Sort Level 10 Step-by-Step Walkthrough

Watch the belt between taps. If it looks crowded, let the animations finish before you touch the next block.

Opening: feed the front row without overcommitting

1. Tap the single Dark Blue block in the middle of the tray’s bottom row. Its marbles start filling the Dark Blue Boxes in columns 1 and 3.
2. Tap the Light Blue block under the Tunnel. It feeds the column 4 Box cleanly, and the Tunnel counter drops to 2 as a fresh block pops out.
3. Tap one — only one — of the two front Pink blocks to clear the Pink Box in column 2. Leave the other Pink exactly where it is.
4. The gaps you just made expose a second Dark Blue block behind the old front line. Tap it to finish the columns 1 and 3 Boxes and slide the next row up.

Mid-game: the Light Blue wall and the Tunnel dig

The second row of Boxes steps up and it is a wall of Light Blue across columns 2, 3, and 4.

5. Tap the newly exposed Light Blue blocks in the middle-right of the tray. You need volume here.
6. Hit the Tunnel again — tap whatever it just spat out — to push the counter down to 1. Keep digging; the trapped colors on the right side have to come out eventually.
7. Pull the Orange blocks from the upper center of the tray and park them on the belt. The next wave of Boxes wants them, and you want them ready.
8. Now tap that second Pink you saved. The third row of Boxes has Pink waiting in columns 1 and 4.
9. Clear the remaining Light Blue blocks to satisfy the rest of the wall and empty the middle of the board.

Cleanup: corners and the last Dark Blue

The endgame belongs to Yellow and Orange, plus one hidden Dark Blue.

10. Wait for the Yellow Boxes to reach the front — they sit at the very bottom of columns 1 and 3 — then tap the Yellow clusters in the top-right and top-left corners of the tray.
11. Send down the last Orange block at the top center.
12. Tap the final Dark Blue block in the top-left corner. It clears the Dark Blue Box buried at the back of column 4, and the belt flushes the board out.

Level 10 Tips Recap

• Two of a color in the tray plus one open Box means one of those blocks is bait. The spare Pink is the whole puzzle.
• The Tunnel is a countdown you control — every clear ticks it, so plan which block you want it to cough up.
• Parking is legal when the Box is guaranteed soon. Orange on the belt in the mid-game is a deposit, not a mistake.
