Marble Sort Level 413 Walkthrough & Solution

Level 413 Board Overview: The Chained Pair

Level 413 is a Hard board on the tile-tray variant: colored tile stacks rise from the tray, the receiver Boxes hang above it, and a conveyor belt runs along the bottom of the screen. The gimmick is impossible to miss — the two Boxes above the center of the tray are chained together, one Red and one Purple, locked to each other like a single linked order. You read them as one target, not two: every pass should feed Red and Purple together.

Underneath that chain the tray is an irregular, roughly six-lane field of short stacks. Blue marker tiles printed with “3” guard the upper left and upper right of the board, and a lone “1” marker sits lower in the middle columns, while the gaps between them fill with plain Red, Purple, Green, Pink, and Blue singles. Three dotted Orange tiles are parked at the bottoms of the columns — easy to reach and easy to regret.

The machinery below is already running. The conveyor starts with Blue-heavy deliveries queued at the front, Green, Red, and Pink runs mixing in behind them, and White showing up later in the cycle. Four loading stacks under the belt stock what comes next, leaning Green, White, Blue, Red, and Purple, with a single Yellow tucked into the second stack. Strip the tray top-down and let the Boxes set the pace; the belt never outruns you if you do.

The Trap in Marble Sort Level 413

The board is rigged to make you feed the belt faster than the Boxes ask. Here is the layout:

• The two Boxes are chained together: the Red Box and the Purple Box hang above the tray linked to each other. Clearing one side while parking the other stalls the chain, so the opening punishes anyone who plays a single color to completion.
• Numbered Blue markers ride the tray: Blue tiles printed “3” and “1” sit in the upper and middle columns. They behave like bulk deliveries and step down through their counts as they pay — powerful when Blue is being asked for, dead weight when it is not.
• Dotted Orange tiles are special drops: the three dotted tiles sit at the bottoms of the columns, and no Orange Box is open at the start. Releasing one early just jams the queue for a color nobody wants yet.
• The belt arrives pre-stocked: the conveyor is the only buffer you have, and it opens with Blue, Green, Red, and Pink already riding. Every delivery you fire without an open Box costs you space you will need mid-solve.

Marble Sort Level 413 Step-by-Step Walkthrough

Treat the chained pair as one order and the level mostly plays itself. Follow the release order.

Opening: move Red and Purple in step

1. Read the chain first: the Red Box and the Purple Box open as a pair. Clear them together, never one side alone.
2. Tap the topmost Red tile in the upper-center column into the Red Box — it sits almost directly under the receiver.
3. Drop the Purple tile beside it into the Purple Box. One matched tile per side keeps the chain balanced.
4. Leave the dotted Orange tiles alone. Nothing on the opening board asks for Orange, and a special drop with no open Box just eats belt space.
5. Do not touch the numbered Blue markers yet. They are Blue’s bulk deliveries and only pay once a Blue order is actually at the front.

Midgame: bank the Blue markers and strip the columns

By the mid-solve frames the tray has thinned out visibly: whole columns are gone, gray empty slots open under the remaining tiles, and the marker counts are stepping down as the stacks above them clear. The conveyor keeps cycling and the next orders move into the front.

6. When the Blue order opens, feed it from the conveyor’s Blue runs and the plain Blue singles in the columns. The numbered markers step down from 3 to 1 as they pay.
7. Bank each marker as it surfaces — a “3” marker clears a big chunk of the demand in one drop, so line it up against the highest open count.
8. Work every remaining column one topmost tile at a time, feeding whichever color the active Box asks for. The buried singles underneath are your real targets.
9. Play the belt in matching batches: when a run of one color lines up in the queue, send the whole run rather than dribbling singles.
10. Prioritize columns that expose two matching tiles in a row — clearing them empties a lane and opens the tray.
11. The dotted Orange tiles finally earn their keep when an Orange Box cycles in. Release them then, and only then.

Cleanup: feed the stragglers

The closing frame catches Level 413 still mid-solve: the tray is down to short columns of singles, the chained pair is still taking its final tiles, and the belt is running Blue and White behind them. There is no shortcut left, only the finishing line.

12. Play only to the active receivers. Every remaining tile is a single waiting for its Box to come to the front.
13. Let the belt cycle: feed the last tiles as their receivers open, and leave the Whites on the belt alone until something is actually asking for them.
14. Keep matching into the chained pair until the tray is empty — the level completes the moment the last tile lands.

Level 413 Tips Recap

• The chained Red and Purple Boxes are one order — feed both sides in every pass or the chain stalls you.
• Numbered Blue markers are bulk deliveries: bank them until Blue is being asked for, then let them step down from 3 to 0.
• Dotted Orange tiles have no Box at the start — ignore them until Orange cycles in.
• In the endgame the tray is nearly empty; play only to the active receivers and let the belt cycle the stragglers in.
