Sand Loop Level 339 Guide: The Sun and Moon Puzzle

This level features a beautiful, split-screen pixel art design: a "Sun and Moon" mosaic. The left half is a cool-toned Moon face (Cyan) on a Purple background with Pink stars. The right half is a warm-toned Sun face (Red) on a Yellow background with Orange details.

It is a Logic Level. Speed won't help you here; the challenge is managing a complex supply tray where the colors you need for the left side are often buried under colors for the right side, and vice versa.

Sand Loop Level 339 Solution: The Split Palette

The canvas is strictly divided down the middle, meaning your timing on the conveyor belt is everything.

Primary Colors: Cyan (Moon Face) and Red (Sun Face). These are your starting focus.
Background Colors: Purple (Left/Moon side) and Yellow (Right/Sun side).
Detail Colors: Pink (Stars on the left) and Orange (Facial features on the Sun).

The Danger Zones: The biggest risk in Sand Loop 339 is the Roped Columns on the far left and right. The Left Rope holds Pink and Orange cups. The Right Rope holds Yellow and Purple cups. Notice the mismatch? The Left Rope holds an Orange cup needed for the Right side (Sun), and the Right Rope holds a Purple cup needed for the Left side (Moon). If you mistime these releases, you will contaminate the wrong side of the canvas.

Fill Order Prediction:

Faces First: The Red and Cyan centers.
Backgrounds Second: The large Yellow and Purple fields.
Details Last: The Pink stars and Orange accents often sit "on top" or are small details filled late in the pour.

Tackling the Converter Cups in Sand Loop 339

The specific obstacle here is the pair of Converter Cups in the second row.

Red Cup with Blue Arrows: Turns Red sand into Cyan sand.
Blue Cup with Red Arrows: Turns Cyan sand into Red sand.

These are traps if used carelessly. You start with pure Red and Cyan cups in the top row. If you use the converters too early, you might waste a perfectly good Red cup by turning it Cyan when you didn't need to, or vice versa. Only use these converters if you have run out of a specific "pure" color and the canvas still demands it. For the most part, treat them as regular cups but watch your input color.

Sand Loop Level 339 Step-by-Step Walkthrough

1. Clearing the Primary Faces

Your first moves are obvious but critical. Tap the two pure Red and two pure Cyan cups in the very top row.

These will begin filling the main volume of the Sun and Moon faces.
Do not touch the Converter cups (row 2) yet. Let the pure colors do the heavy lifting first to clear the board space.

2. Cracking the Center Column

Once the top row is gone, you are left with the Converters and the central block of cups (Mystery Boxes and standard colors).

Focus on the middle column first. You need to dig down to the Purple and Yellow cups hidden in the center.
The Mystery Boxes (Black cups with "?") are wildcards. Tap them when the conveyor belt has a 2-slot gap. They usually reveal background colors (Yellow/Purple) needed to start filling the edges of the artwork.

3. Managing the Rope Dependencies

This is the hardest part of Level 339. The ropes on the left and right bind two cups together.

The Left Rope (Pink/Orange): The Pink is for the Moon stars (Left), but the Orange is for the Sun details (Right). When you finally clear the cups blocking this rope, ensure you have space on the belt.
The Right Rope (Yellow/Purple): The Yellow is for the Sun background (Right), but the Purple is for the Moon background (Left).
Strategy: Do not release a rope until the "Face" (Red/Cyan) is largely finished. You don't want Purple sand mixing into the Moon's face. Wait until the sand pile is high enough that the background colors will roll off to the sides naturally.

4. The Final "Switch" Cleanup

At the very bottom of the tray (rows 5 and 6), you'll see cups with circular arrows (Orange, Pink, etc.). These are often needed for the final tiny details, like the eyes or specific stars.

Save these for the very end. The Orange cups, specifically, are crucial for the Sun's mouth and winking eye. If you waste the Orange cups early on the general yellow background, you will fail the level at 99%. Keep an Orange cup in reserve for the final 5%.
