Marble Sort Level 213 Walkthrough & Solution

Level 213 Board Overview: The Two-Compartment Tray

Level 213 plays on the tile-and-block variant of the Marble Sort board, and the first thing you notice is the split. A divider runs down the middle of the tray, separating a left compartment from a right one, with a chute below carrying marbles down toward the bottom receiver. The top bar shows Level 213, a coin counter, and three single-use power-ups (magnet, jack, and snowball) — nice insurance, but not needed if you play in order.

The left compartment is stacked with Yellow — two big yellow blocks, each fitted with a clamp-and-ring holder, sitting directly on top of Green blocks. The right compartment opens much lighter: Light Blue, Green, and Red on the top row, with Green and Purple tucked underneath. The bottom two rows of the right side are already thin, which tells you this half of the board empties fast.

Below the grid, the chute is pre-loaded with Yellow, Red, and Light Blue marbles waiting to feed the receiver. The receiver bins ask for Yellow, Green, Light Blue, Red, and Purple — and scattered grey ’?’ mystery bins hide part of the demand. You cannot see the full goal order at the start, so the opening is about reading the bins before you commit to the chute.

The Trap in Marble Sort Level 213

The board is rigged to make you feed the chute before the bins are ready. Here is the layout:

• Grey ’?’ mystery bins sit in the receiver: part of the goal is hidden at the start. You cannot plan a long combo around a color whose bin has not revealed itself yet.
• The chute pre-loads three colors at once: Yellow, Red, and Light Blue are already riding the belt when the level opens. If you tap them before a matching bin is open, the queue jams.
• The yellow holder blocks clamp the left side: they sit above the Green blocks you actually want, so the left compartment is a two-stage peel — remove the holders, then feed what they were covering.
• The right compartment runs shallow: its bottom rows empty out quickly, which means the second half of the level is almost entirely about the conveyor queue, not the tray.

Marble Sort Level 213 Step-by-Step Walkthrough

Read the receiver before you touch the chute. Follow the release order.

Opening: read the bins before the belt

1. Survey the bottom receiver first. Note which colors already have open bins — Yellow, Green, Light Blue, Red, and Purple are visible — and mark the grey ’?’ mystery bins as unknown demand.
2. Feed Light Blue from the right compartment’s top row into its open bin. This is the safest first drop on the board.
3. Follow with Green from the same top row — the Green bins are open and the left-side stacks are full of Green waiting below the holders.
4. Play the pre-loaded chute only when the marble matches an open bin. A Red or Yellow on the belt is fine to tap; it is not fine to tap when no Red or Yellow bin is showing.
5. Leave the yellow holder blocks alone for now. They are clamped over the Green stacks, and peeling them early just parks Yellow on the belt with nowhere to go.
6. Keep the queue moving with matching colors only. Every safe drop clears bin space and keeps the chute from backing up.

Midgame: thin the right side, peel the holders

By the middle of the solve the right compartment’s bottom rows are empty and the receiver is filling in runs — columns of Green, Light Blue, Red, and Purple are stacking up while the grey ’?’ bins still hold their secrets. This is the moment to attack the left side.

7. Feed Light Blue and Green in runs as their bins cycle forward; these are the colors that finish fastest.
8. When a Yellow bin slides to the front, pull the yellow holder blocks off the left stack and drop them into it.
9. With the holders gone, feed the exposed Green blocks straight into the Green bins.
10. Match the conveyor order: release the queued marbles in the order they ride the belt so the chute never stalls.
11. When a ’?’ mystery bin reveals its color, retarget that color immediately — freshly revealed bins often match whatever is already riding the belt.
12. Prioritize any column that exposes two matching blocks in a row; clearing it empties part of the tray and opens the receiver.

Cleanup: finish the final columns

The run ends on a board with the receiver nearly stacked — columns of Red, Yellow, Green, and Purple mostly filled, only the mystery slots left — and the video’s final frame shows a red REPLAY banner over that mid-solve board rather than a clean empty tray. Play the ending conservatively.

13. Every remaining marble belongs to a bin that is already open — play only to the active front row.
14. Let the chute cycle the stragglers in: the last Light Blues and Greens feed as their bins slide forward.
15. When only ’?’ bins remain, reveal them one at a time and feed the match the moment it appears.
16. Finish the last column and the tray empties; the level is complete.

Level 213 Tips Recap

• The receiver hides part of its demand behind grey ’?’ mystery bins — never stack a combo on a color you cannot confirm is wanted.
• Only feed colors with an open bin; the pre-loaded Yellow, Red, and Light Blue on the chute are bait until their bins show.
• The right compartment empties fast, so the conveyor becomes the whole game in the second half — keep the queue in order.
• Save the yellow holder blocks on the left until a Yellow bin is front and center, then peel them and feed the Greens underneath.
