Marble Sort Level 203 Walkthrough & Solution

Level 203 Board Overview: The Locked Marble Funnel

The walkthrough opens on the level map with Level 203 highlighted and Level 204 waiting behind it as a Hard board. Tap Play and the marble grid loads: a tall upper board of colored marbles packed cell by cell, a narrow funnel through the middle, and a collection tray below whose columns sort every marble that drops.

Green is the workhorse color of this board. The upper grid is green-heavy, with the greens layered through the middle rows while Blue, Red, Yellow, Cyan, and Pink hold the flanks and the lower edge. Scattered across the grid are grey mystery ’?’ cells that hide what is underneath, and numbered locks marked ‘3’ that sit in several cells and refuse to open until marbles have passed through them.

Below the funnel, the collection tray is divided into color columns. The opening view shows the columns already running: green, yellow, orange, pink, blue, red, and white groups stacked at the bottom of the tray, ready to receive whatever the grid sends down. The level ends when every marble above has been routed through the funnel and sorted into its column below.

The Trap in Marble Sort Level 203

The board is built to make you feed the funnel faster than the locks let it clear. Here is the layout:

• Numbered locks block the path: cells marked ‘3’ need several marbles routed through them before they break. The locks sit at the edges of the middle rows, so the safest colors are the ones in the open center.
• Mystery ’?’ cells hide half the grid: grey tiles blanket the outer cells. You cannot plan the flanks until they reveal, and the reveals drop new marbles into the flow at their own pace.
• The funnel is the bottleneck: every marble has to pass through the single narrow opening. Send mixed colors and they jam in the neck; send same-color batches and the tray sorts them instantly.
• The edge groups have nowhere to go early: the yellow groups at both ends of the tray stay parked until the endgame, and a red and pink cluster lingers at the lower right until the very last drops.

Marble Sort Level 203 Step-by-Step Walkthrough

Feed the center first, break the locks, then sweep the edges. Follow the release order.

Opening: clear the revealed center

The upper grid starts with a handful of revealed cells surrounded by ’?’ tiles and locks. Those revealed marbles are the whole opening: green, cyan, red, pink, and orange sit in the middle rows with clear paths to the funnel.

1. Tap the revealed green and cyan marbles first — they are the center of the grid and the easiest drops on the board.
2. Drop the red and pink marbles from the middle rows next, in same-color batches so the tray columns fill cleanly.
3. Send the orange marble from the center row down behind them.
4. Do not touch the grey ’?’ cells yet. Every reveal costs a funnel slot, and the opening is about volume, not discovery.
5. Keep the drops to the open center until the first collection columns start to fill.

Midgame: break the locks and reveal the grid

Once the center colors are flowing, the locks at the edges of the middle rows become the gatekeepers. Each ‘3’ lock needs several marbles routed through it, so you have to keep traffic moving through those cells on purpose.

6. Route marble traffic through the numbered locks deliberately — every marble that passes wears one point off the ‘3’.
7. Start peeling the mystery ’?’ cells on the flanks as the center thins out. If the reveal matches a column that is actively collecting, drop it; if not, leave it and work the other side.
8. Feed the funnel in same-color runs. The tray sorts by color, so a batch of one color clears a column in a single pass instead of jamming the neck.
9. As the locks break, the green-heavy middle opens up — keep the greens moving first, then the blues and yellows they were covering.
10. When a mystery reveal produces a second copy of a color already in the funnel, drop them together; the pair clears the column faster than two single drops.

Cleanup: sweep the edges

With the grid mostly worked, the board thins to the stragglers: the yellow groups parked at both ends of the tray and the final red and pink cluster at the lower right. The end frames show the tray nearly empty, with only those edge groups left to sort.

11. Finish the yellow groups at the tray’s edges — they waited the whole level, and their columns are open now.
12. Drop the remaining red and pink cluster last, keeping the two colors separated so each lands in its own column.
13. Let the last few marbles ride through the funnel on their own; do not force extra drops once the columns are closing.
14. The level completes when the tray has swallowed the final marble and every column is full.

Level 203 Tips Recap

• Feed the revealed center before anything else — green, cyan, red, pink, and orange open the level, and the locks are not worth fighting early.
• Route marbles through the numbered ‘3’ locks on purpose; every pass weakens them, and they gate the midgame.
• Reveal ’?’ mystery cells only when the funnel is clear, and drop reveals in same-color batches.
• In the endgame the tray is nearly empty — sweep the yellow edges and the final red and pink cluster, and the level closes itself.
