Marble Sort Level 412 — Walkthrough and Solution

Marble Sort Level 412 is a board that hides its true difficulty behind a friendly-looking first row. The key is to ignore the Red and Yellow marbles sitting loose at the bottom of the Top Tray until you have cleared the correct front Boxes. If you tap them early, they will occupy your Conveyor Belt for many moves and block the flow you need to break open the Iced Boxes and Tunnels.

The Top Tray is split into seven columns. Columns 2 and 6 are sealed by Iced Boxes: column 2 locks a Light Blue, a dark Blue, and a Purple marble, while column 6 freezes a Red, an Orange, and a Green one. Column 4 holds a vertical stack with a Red marble, a Tunnel marked with a '3', a Green marble, another Tunnel with a '3', and a Brown marble at the bottom. Columns 1, 3, 5, and 7 are open work zones. Five loose marbles sit along the bottom edge of the Top Tray: Purple, Red, Brown, Yellow, and Pink.

The lower Boxes in the front row demand, from left to right: Brown, Orange, Pink, and Purple. Behind them, the queues stack as follows: the far-left queue holds Brown then Orange then Yellow; the inner-left queue holds Orange then Brown then Green then Orange; the inner-right queue holds Pink then Green then Pink then Pink; the far-right queue holds Purple then Pink then Purple then Brown. Notice that Red has no Box anywhere in the queues, and Yellow's Box is buried deep on the far left.

The trap is the loose Red marble and the loose Yellow marble at the bottom of the Top Tray. They look like easy taps, but they have no immediate destination, so they will sit on your belt and choke it for the entire midgame. You must clear the front row first, then use the Yellow marble only after its Box appears.

How to Beat Marble Sort Level 412 — Step-by-Step

Clear the Front Row Without Touching the Bait

1. Tap the loose Brown marble resting in the bottom middle of the Top Tray.
2. Pull the next Brown marble from the bottom of column 5 and feed it to the same Box.
3. That fills the front-left Brown Box, which brings the first Orange Box forward.
4. Now tap the loose Pink marble on the right side of the Top Tray and send it to the Pink Box.
5. Grab the loose Purple marble from the bottom corner and drop it into the Purple Box.
6. Tap the Orange marble at the bottom of column 1 and the Orange marble at the bottom of column 5, routing both to the Orange Boxes.
7. Leave the loose Red and Yellow marbles alone. Your belt must stay empty for the next phase.

Melt the Ice and Open the Flanks

1. Once the Yellow Box is active on the far left, tap the loose Yellow marble and send it to that Box.
2. Pull the remaining Yellow marbles from column 1 to finish that Box.
3. Focus on columns 3 and 7: tap the Green marbles there and feed them to the Green Boxes that have appeared in the center queues.
4. Clearing those columns will shatter the ice on the right side, releasing the Green, Orange, and Red marbles trapped in column 6.
5. Drop the Green and Orange marbles into their matching Boxes immediately.
6. Hold the Red marble on the belt for a few moves until a Red Box becomes visible in the queues.

Pop the Tunnels and Finish

1. Tap the accessible marbles in column 4 to reduce the Tunnel counters from 3 to 0.
2. When the top Tunnel empties, route its marbles into the Pink and Purple Boxes on the right side.
3. Wait until your belt has at least two empty slots before tapping the lower Tunnel, because it will release the final colors needed for the Brown and Pink Boxes in the back rows.
4. Sweep up the Red and Light Blue marbles from the left Iced Box to complete the level.

Tips & tricks

• Always keep your Conveyor Belt as empty as possible during the first phase; the Red and Yellow marbles are decoys.
• Use the countdown on the Tunnels as a timer: only tap the lower Tunnel when you have space for two marbles.
• Prioritize clearing the side columns (1, 3, 5, 7) because they unlock the Iced Boxes that hold critical colors.
• Remember the exact order of the front row: Brown, Orange, Pink, Purple. Do not deviate.

Common mistakes

• Grabbing the loose Red or Yellow marble early, which jams the belt and halts progress.
• Ignoring the countdown on the Tunnels and tapping them without enough belt space, causing a backlog.
• Clearing the front row out of order, which reveals the wrong Boxes and forces you to wait.
