Sand Loop Level 21 Guide: The Banana Puzzle

This is the "Pixel Banana" level. It looks friendly—bright yellow fruit, pink background—but don't get comfortable. Sand Loop Level 21 is a classic "Ice breaking" speed level disguised as a simple color fill. The main hook here is the massive amount of pink background you need to fill, which is frustratingly blocked by a stubborn Ice Block in the top left corner of the tray. If you don't crack that ice efficiently, you will run out of conveyor slots before you can even touch the background.

Sand Loop Level 21 Solution: The Pixel Banana

Let's break down the image on the top screen. You aren't just dumping sand; you are painting specific layers.

Color Palette Deep Dive

Bright Yellow: The core of the banana. This is your primary filler for the center.
Orange/Light Brown: This forms the shadow on the right side of the banana curve.
Dark Red/Maroon: Only two small spots—the tip of the stem and the bottom nub. Do not waste these cups on the main body.
Pastel Pink: The background. It covers the most surface area but is trapped behind the ice.

The "Danger Zones"

The biggest risk in Sand Loop Level 21 is the Shadow Curve. The orange pixels hug the right side of the yellow body tightly. If you send a burst of Orange cups too early, they will bleed into the Yellow zone. If you send them too late, the Yellow will cover the shadow area, leaving you with a flat, unfinished banana. You need a "Yellow-Orange-Yellow" sandwich approach.

Fill Order Prediction

Physics dictates the strategy here. The sand falls from a central point and piles up.

Bottom Tip: The dark red cup needs to go fairly early or it gets buried.
Core Body (Yellow + Orange): These need to alternate to build the curve.
Background (Pink): This is the final flood. You can't finish the background until the fruit is mostly solid.

Tackling the "4-Hit Ice Block" in Sand Loop Level 21

Look at the top left of your supply tray. There is a blue Ice Block with the number 4 on it. This is your primary antagonist.

This block is locking up a critical column of cups. Until you break it, you are playing with a restricted hand. The "4" means you need to make four matches adjacent to it or clear four cups that touch it (depending on the specific mechanic version, usually adjacent matches or clearing adjacent cups cracks it). In this specific layout, you have a Maroon cup sitting right next to it, and a Yellow one below that. You have to prioritize clearing the cups immediately adjacent to this block to get access to the buried Pink cups underneath.

If you ignore the Ice Block, you will run out of Yellows and Oranges and be left with no legal moves while the Pink background stays empty.

Sand Loop Level 21 Step-by-Step Walkthrough

This level is about clearing the "Dependency Chain." The Pink cups (background) are dependent on breaking the Ice. The Ice is dependent on clearing the Maroon/Yellow stack next to it.

1. Clearing the Maroon Blocker

Your first moves must be precise. You have a Dark Red/Maroon cup in the top left (next to the ice) and another buried at the bottom center.

Send the top-left Maroon cup to the conveyor immediately. This counts as your first "hit" or clearance next to the Ice Block.
This also sets the bottom tip of the banana on the canvas. Don't worry if it looks like it's floating; the sand will settle.

2. The Yellow-Orange Weave

Now you have access to the main supply. You need to build the banana body.

Start feeding Yellow cups. The layout has a heavy stack of Yellows on the left.
Crucial Step: Every 2-3 Yellow cups, slip in an Orange cup. The Orange cups are mostly on the right side and bottom center.
Do not send all the Oranges at once. You want them to mix with the Yellows to create that textured shadow effect on the right side of the fruit. If you dump them all at once, you get a solid orange block, which the game might reject as "too much contamination."

3. Cracking the Ice (The Pink Release)

As you pull the Yellows from the left column (below the Maroon cup you already used), the Ice Block will take damage.

Once the count hits 0, the block shatters.
This reveals a fresh stack of Pink cups. Do not use them yet.
Wait until the banana shape is clearly defined on the canvas. If you pour Pink now, it might cover the Yellow/Orange pixels you still need to place.

4. Filling the Pink Background

Once your banana looks mostly yellow with an orange shadow:

Unload the Pink cups rapidly. You can be messy here.
The Pink sand will naturally slide off the pyramid of Yellow sand you built, filling in the corners and sides of the canvas perfectly.
Keep an eye on the conveyor capacity (0/5). Don't jam the belt. Send 3 pinks, wait for them to pour, then send the rest.

5. The Final Stem

You likely have one Dark Red cup left (usually near the bottom of the tray).

Save this for the very end or near the end.
It needs to land on the very peak of the yellow pile to form the top stem. If you send it too early, it gets buried by yellow sand. If you send it last, it sits perfectly on top.

Victory Check: Ensure the Orange shadow is visible on the right and the Pink background fills the corners completely. If you have gaps in the corners, you didn't send enough Pink cups or you sent them too slowly, allowing the sand to clump in the middle.
