Marble Sort Level 664 — Walkthrough and Solution

Marble Sort Level 664 presents a board dominated by a blocked center, numerous Hidden Boxes, and restricted lower corners. The primary colors early are Red, Yellow, and Green, yet the true challenge is limited open space. The middle is entirely obstructed, so you must clear the outer corners before addressing the interior.

The top area narrows like a funnel, but the central path is sealed. Your only accessible starting points are the lower left and lower right corners. On the left, a Red block sits beneath a Purple and Blue tunnel structure. On the right, an Orange block lies below a striped 2x2 zone bordered by Blue and White. The front row of Boxes demands Red, White, Yellow, and White in that order. Until these are satisfied, no other moves are safe.

In the Top Tray, colors are split apart. The exposed Red block at the lower left is your key. In the striped zone on the right, a grid contains Yellow, Red, Light Blue, and another Yellow. The Orange block at the far bottom right appears free, but resist it: Orange is not needed until later, and dropping it now would fill the Conveyor Belt with unusable marbles. The center holds a bottom row of Hidden Boxes concealing Purple, Green, Red, and Green. Above them, a row of icy Hidden Boxes, then a visible mix of Green, Yellow, White, Purple, and Green. The topmost row is another set of Hidden Boxes.

The initial clear is pivotal: dropping the lower-left Red fills the front-left Red Box, which shifts the queue and exposes a Yellow Box. This unlock lets you safely use the striped right section.

How to Beat Marble Sort Level 664 — Step-by-Step

Phase one: Corner clearing

1. Tap the Red block at the lower left; it fills the first Red Box.
2. Do not tap the Orange block at the lower right; it is a decoy.
3. In the striped 2x2 section, tap the Yellow block at its bottom right; this clears the third column's Yellow Box.
4. After the first Red Box clears, the board shifts, revealing a Light Blue Box and more Yellows.
5. In the striped zone, tap the Light Blue block at its lower left; send it to the new Light Blue Box.
6. Tap the remaining Yellow block from the striped zone's upper left; it clears the next Yellow Box.
7. Now tap the lowest row of Hidden Boxes in the center; this exposes the Purple and Green blocks above them.

Phase two: Icy center and midgame

1. Extract marbles from the Purple and Blue tunnel on the left, but only when a matching Box is visible.
2. Clear the newly exposed Purple and Green blocks in the center row; this brings the icy Hidden Boxes into play.
3. Keep an eye on the Conveyor Belt; as ice blocks reveal, you may drop colors without immediate Boxes, so maintain two or three empty slots.
4. When a Red Box cycles to the front, tap the final Red block from the striped area's top right.
5. After the icy row breaks, focus on the upper center cluster with Green, Yellow, White, and Purple; remove Greens first since they are heavily needed.

Phase three: Top tray reveals and final sweep

1. When the bottom Boxes shift to Pink and Dark Blue, do not panic; the needed marbles are in the top Hidden Boxes.
2. Click the top Hidden Box row one at a time, from left to right; revealing multiple at once would overload the belt.
3. Clear any remaining visible White blocks from the upper right, as they must vanish before Pink Boxes fully activate.
4. Finally, drop Pink and Dark Blue marbles precisely as they appear; keep the belt under five slots to finish.

Tips & tricks

• Always check the front Boxes before making any drop; match the color exactly.
• Keep the Conveyor Belt as empty as possible, especially during the middle phase.
• Reveal Hidden Boxes slowly, one at a time, to control the flow of marbles.

Common mistakes

• Tapping the lower-right Orange block too early, which fills the belt with unusable marbles.
• Revealing multiple Hidden Boxes at once, causing a flood of colors without matching Boxes.
• Ignoring the Conveyor Belt capacity, leading to a jam before the correct Boxes appear.
