Marble Sort Level 171 Walkthrough & Solution

Level 171 Board Overview

Level 171 opens with a crowded tray: fifteen marble slots packed with nine different colors, while three wooden crates sit among them and cover part of the play area. A heavy cluster of Blue marbles rests near the top, and Brown, Red, Yellow, Green, Cyan, White, Orange, and Purple scatter through the rows below.

The conveyor is already busy when you start. The first queue ships three Orange marbles followed by a run of Purple — and they feed straight into a board that has nowhere to put them yet. Meanwhile the receiver boxes are asking for Green, Cyan, Green, and Blue, so the early game is about draining those four boxes while the Orange and Purple wave backs up behind them.

The three wooden crates split the tray into pockets. You cannot treat the board as one continuous surface — each pocket has to clear its own way out, and a color stuck on the wrong side of a crate has to wait for a box to cycle its way.

The Trap in Marble Sort Level 171

The board front-loads the wrong colors. Here is the layout:

• A conveyor full of Orange and Purple: the opening queue delivers three Orange then a run of Purple before any Orange or Purple box exists.
• Receiver boxes that start on Green, Cyan, and Blue: every opening box ignores the colors the conveyor is shipping.
• A heavy Blue cluster near the top: the biggest single color block on the board, sitting above rows that still hold Yellow and White — neither of which has a box yet.
• Three wooden crates: they hide slots and split the tray into pockets, so marbles on one side often cannot reach the box that wants them.

The level wants you to panic and tap everything in reach. Do that and the Orange and Purple wave buries the tray. The winning line is to let the wrong colors stack while you drain the colors that actually have boxes.

Marble Sort Level 171 Step-by-Step Walkthrough

Opening: drain the boxes you have

1. Tap the Green marbles you can reach into the left Green box — the first box on the left and the safest early target.
2. Feed the Cyan marbles into the Cyan box; Cyan appears in several rows, so keep it as your steady early color.
3. Work the second Green box with the Green marbles from the upper rows.
4. Drop the Blue marbles into the Blue box, pulling the big top cluster down through the tray.
5. Leave the Orange and Purple marbles alone as the conveyor keeps delivering them — they have no boxes yet, and tapping them just jams the belt.
6. Do not touch Yellow or White either; neither has a box in the opening row, so both are pure bait.
7. As front boxes fill and clear, keep the loop going: feed every new front-row box that matches something reachable, and keep Green, Cyan, and Blue as your workhorses.

Midgame: the Brown block arrives

The middle of the level is defined by the conveyor. A long train of Brown marbles — seven in a row — starts shipping in right as the receiver boxes cycle to Purple, Orange, Cyan, and Cyan.

8. When the boxes flip to Purple and Orange, finally clear the Orange and Purple backlog that has been stacking in the tray.
9. Ride the Cyan box: Cyan keeps coming back through the front row, so it stays a reliable drain throughout the midgame.
10. The Brown train has no Brown box when it starts arriving — let it stack in a tray pocket instead of forcing it into the belt.
11. Keep the Brown run contained in one pocket while you feed the live Purple, Orange, and Cyan boxes around it.
12. The moment a Brown box cycles into the front row, drain the parked Brown marbles fast before the next wave arrives.

Cleanup: ride the cycle to the finish

By the endgame the tray has thinned to a few stacks and the conveyor runs dry.

13. With the conveyor empty, the only marbles left are the ones in the tray — count them against the box requests before every tap.
14. Feed the final Purples and Oranges as their boxes come back around.
15. Let the last Browns slide into the Brown box the moment it appears.
16. Finish with the remaining Green, Cyan, and Blue stragglers — the final box to seal is Green.

Level 171 Tips Recap

• The opening conveyor ships Orange and Purple long before any box wants them — let them stack, never tap them early.
• Play only colors with a live box: Green, Cyan, and Blue carry the opening; Yellow and White are bait.
• The seven-Brown mid-game train is the trap — park it in a tray pocket until the boxes cycle to Brown.
• Once the conveyor runs dry, count every remaining tap: match the last tray colors to the boxes still open.
