Marble Sort Level 229 — Walkthrough and Solution

Marble Sort Level 229 is a deceptive puzzle that hides its true demands behind a curtain of Mystery Boxes and four Tunnels. The winning strategy is to clear the bottom row's visible receivers first—Brown, Orange, Pink—and only then engage with the midgame and top-corner Tunnels. Avoid the front Light Blue cluster at all costs until its matching Box appears.

The board features a Top Tray with a protruding front line containing Light Green, Brown, Light Blue, and Orange, backed by Pink, Brown, Light Green, and Dark Green. Below, a red horizontal wall splits the upper area, while the bottom receiving zone has four columns: the leftmost shows Brown, Pink, Light Blue, Brown; the rightmost shows Pink, Dark Green, Dark Grey, Pink. The two middle columns are capped by Brown and Orange Boxes but hide three rows of question-marked Hidden Boxes underneath, making late-game planning impossible until they are exposed.

The initial bottom Boxes demand, from left to right: Brown (two columns), Orange, and Pink. The front line of the Top Tray offers clusters of Light Green, Brown, Light Blue, and Orange, but only Brown, Orange, and Pink are needed immediately. The trap is the front Light Blue cluster: tapping it early would occupy Conveyor Belt space with a color that has no receiver, causing a jam.

To open the path to Pink, you must deliberately sacrifice the front Light Green cluster, letting it sit on the belt as a temporary placeholder. This calculated move frees the Pink cluster behind it, allowing you to clear the final receiver of the front row.

How to Beat Marble Sort Level 229 — Step-by-Step

Phase one: Clearing the Front Row

1. Tap the front Brown cluster; it drops into the two leftmost Brown Boxes.
2. Tap the front Orange cluster; it fills the Orange Box in the third column.
3. Release the front Light Green cluster; it lands on the Conveyor Belt as a necessary sacrifice.
4. Tap the Pink cluster; it fills the rightmost receiver, completing the front row.
5. Leave the front Light Blue cluster untouched—it is bait.

Phase two: Triggering the Midgame Tunnels

1. After the bottom shifts up, new receivers appear: Light Green and Dark Green.
2. The Light Green cluster parked on the belt automatically flies into the revealed Light Green Box, freeing belt space.
3. Release the Dark Green cluster from the right side of the Top Tray to fill its receiver.
4. Clear blockers in front of the two middle Tunnels as their matching Boxes appear below.
5. Let the Tunnels dispense one cluster at a time, matching outputs to the middle columns' Hidden Boxes.
6. Continue exposing Hidden Boxes to learn the colors needed for the rest of the level.

Phase three: Beating the Top Corners

1. Now focus on the outer bottom columns: Pink, Light Blue, and Dark Grey Boxes must be cleared to unlock access to the upper sides.
2. Flip Mystery Boxes near the top corner Tunnels, but only drop colors that have a waiting Box below.
3. If a Mystery Box reveals an unneeded color, leave it in the tray to avoid belt congestion.
4. Once blockers are gone, the top Tunnels release final sequences; use your preserved belt space to catch and route them to remaining Boxes.
5. Clear one color at a time, and the level resolves itself.

Tips & tricks

• Always verify that a color has a matching Box before you send it down—this prevents belt clutter.
• Use the Conveyor Belt as a temporary holding area, but never let it fill with colors you can't place.
• When a Tunnel dispenses, immediately check the new Hidden Boxes to plan your next move.

Common mistakes

• Tapping the front Light Blue early, which wastes belt space and delays your progress.
• Dumping Mystery Box colors that aren't needed, causing late-game jams.
• Ignoring the middle columns' Hidden Boxes, leading to surprise demands you can't meet.
