Sand Loop Level 129 Guide: The Retro Yellow Circle Puzzle

This level is a massive nostalgia trip. You're painting what looks suspiciously like a retro arcade character—a big yellow circle with orange shading, cut in half by a bold purple horizontal stripe. It’s not a speed run. This is a logic puzzle disguised as a painting task. The challenge here is the tray layout. You have tons of "Mystery Cups" (the grey ones with question marks) and locked columns that prevent you from accessing the colors you actually need.

Color Palette:

Bright Yellow: The main body of the circle.
Orange: Shading on the yellow circle.
Purple: The distinct horizontal stripe cutting through the middle.
Cyan: The background sky.
Blue: Darker shading for the background/corners.

Sand Loop Level 129 Solution: Deconstructing the Circle

Look at the top screen. You are dealing with a layered image, but the fill order isn't standard.

The Stripe First: The purple stripe is the most dangerous element. It cuts right through the middle. If you paint the yellow body too early without addressing the stripe, you might mess up the layering. However, usually, background/large fills happen first.
Danger Zones: The orange shading inside the yellow circle is tricky. It's not a solid block; it's scattered pixels. You need clean bursts of orange, not a continuous stream, or you'll muddy the bright yellow.
Fill Order Prediction: You will likely need to establish the background (Cyan/Blue) and the main body (Yellow) roughly at the same time, but the Purple stripe is a specific "detail" layer that needs precise timing.

Tackling the "Mystery Stack" in Sand Loop Level 129

The biggest obstacle in Level 129 isn't the painting itself—it's the Grey Mystery Cups. Look at the center columns. They are absolutely choked with them.

Why they suck: You cannot see what color is inside a mystery cup until you put it on the belt.
The Risk: If you pull a mystery cup and it turns out to be Purple when you needed Yellow, you have to waste it. Wasting takes time and risks overfilling the wrong part of the canvas.
The Strategy: You have to play them to clear space, but play them slowly. Do not flood your conveyor belt with 5 mystery cups at once. You will inevitably get a color collision. Treat them like unexploded ordnance. Handle with care.

Sand Loop Level 129 Step-by-Step Walkthrough

This level requires patience. You have a 0/5 capacity, which is generous, but don't let that fool you. If you fill all 5 slots with garbage, you're dead.

1. Breaking the Ice (Literally)

On the far left and right columns, you have Ice Blocks with the number "7" on them.

You cannot access the keys or the cups below them until these are gone.
Action: Immediately start feeding the correct colors to chip these down. The tray gives you visible Blue and Cyan cups at the top. Use these immediately to clear the top layer and start working on the ice. Do not hoard the visible colors; you need to dig.

2. The Red Key Dilemma

On the right side, there is a Red Lock blocking a column. The Red Key is buried on the bottom left.

This is a cross-map dependency. You have to clear the left side column to get the key for the right side lock.
Focus your efforts on the left column first. Use the Yellow and Cyan cups available to churn through the mystery cups in the middle if you run out of valid moves on the left.
Goal: Get that Red Key ASAP. The right column holds critical colors you are likely starving for.

3. Managing the Gold Lock

The Gold Lock is on the left side, but the Gold Key is at the bottom right.

It's the inverse of the Red Key. You have a classic "X" dependency. Left unlocks Right, Right unlocks Left.
Don't Panic: You don't need to unlock both simultaneously. Pick one side (usually the left side with the Red Key is easier to reach first) and drill down.
Once you get the Red Key, the right column opens up, giving you access to the Gold Key. It’s a domino effect.

4. Painting the Purple Stripe

As you churn through the mystery cups in the center, you will randomly get Purple cups.

Hold Fire: Do not just toss purple cups onto the belt whenever they appear. Wait until the purple stripe area on the canvas is actually approaching the pour nozzle.
If you send a Purple cup too early, it will paint over the Yellow/Orange section or the background.
Watch the progress bar. If the nozzle is over a yellow section, discard the purple cup (let it pass without pouring) or hold it in the buffer if you have space (though with mystery cups, holding is risky).

5. The Final Fill (Yellow vs. Orange)

The hardest part of the art is the Yellow/Orange mix.

These colors are visually similar in the tray (sometimes orange looks like dark yellow).
Pay close attention to the pixels. The Orange is for shadows.
When you see a mix of Yellow and Orange cups coming down the belt, spacing is key. Leave a 1-second gap between a Yellow cup and an Orange cup. This allows the dispenser to switch "modes" cleanly without bleeding the orange shadow into the bright yellow face.

Keep your slots open (keep it at 2/5 or 3/5 maximum) so you can juggle the bad RNG from the mystery cups. Good luck.
