Level 107

Sand Loop Level 107: Mastering the Moonlit Mountains Excavation

Welcome to the ultimate walkthrough for Level 107, "The Moonlit Mountains." This stage is a significant difficulty spike in Sand Loop, testing your ability to manage resources and plan. Unlike standard levels where you can simply tap the top cup, Level 107 requires you to think like an archaeologist. You are not just painting; you are digging. The challenge lies in the fact that the color you need the most (Purple for the sky) is buried at the very bottom of the stack, protected by complex countdown gates.

To succeed, you must resist the urge to complete the picture immediately. Instead, you must focus on "overburden removal"—clearing the top layers of Cyan and Blue not just to paint the mountains, but to unlock the gates that guard the Purple paint below. If you mismanage the early game, you will paint yourself into a corner with a half-finished sky and no Purple cups left to fill it.

Core Challenge: The Excavation Paradox

The primary difficulty of Level 107 is the disconnect between the visual layout of the artwork and the physical layout of your cups.

• Visuals: The mountains are at the bottom, taking up roughly 30% of the canvas. The sky is at the top, taking up 70%.
• Supplies: Your supply tray is inverted. The Mountain colors (Cyan/Blue) are on top. The Sky color (Purple) is buried underneath.
• The Trap: If you fill the mountains first, you will run out of "digging" cups needed to unlock the bottom of the tray.

Stage Objectives

To achieve a three-star rating and avoid the "Restart" button, follow these core objectives:

1. Unlock the Flow: Do not focus on perfect painting initially. Focus on breaking the three Countdown Gates located in Rows 2, 3, and 4.
2. Belt Management: Keep your conveyor belt (0/5 slots) flowing. Never let it get clogged with colors you don't currently need.
3. The 70% Rule: Dedicate about 70% of your early moves to clearing cups for the purpose of unlocking gates, and only 30% to actually painting the canvas.
4. Strategic Wastage: Be prepared to "waste" specific cups (tap them into an overflow area or a finished section) to keep the excavation moving.

The Countdown Mechanics

This level introduces "Adjacency Locks," represented by grey arches with numbers. These function differently than standard locks.

• Mechanism: The number on the gate (e.g., '2' or '3') represents the number of adjacent cups you must clear.
• Adjacency: Clearing a cup immediately to the left, right, or above the gate contributes to the count.
• Zero State: Once the counter hits zero, the gate shatters, revealing the locked cup underneath.

The Palette Strategy

Understanding the color hierarchy is crucial for this level.

• Purple (Priority Tier 1): The scarcest resource initially. You must fight to access the bottom two rows where this resides.
• Cyan & Blue (Priority Tier 2): These are your "fuel." Use them to break gates. Treat them as tools rather than paint until the gates are open.
• Cream (Priority Tier 3): The detail color. It is locked behind the hardest gate (the Center Gate). Save this for last.

Strategic Phase 1: Breaking the Surface

The first 20 moves of Level 107 are scripted. You cannot access the Purple paint yet. Do not panic. Your goal here is to clear the "debris" (Cyan and Blue cups) to expose the internal machinery of the level.

Initial Tray Analysis

At the start, your tray consists of roughly 85% Cyan and Blue cups arranged in a jagged pattern.

• Row 1 (Top): Exposed Blue, Cyan, Blue, Cyan, Blue.
• Row 2: Mostly Cyan, shielding the Center Gate.
• Row 3: A mix of Blue and Purple, shielding the Side Gates.

The "Clean Sweep" Tactic

Do not try to paint the mountains perfectly yet. You want to clear the top two rows as fast as possible to reveal the Countdown Gates.

• Action: Rapidly tap the top row cups. If your mountain canvas area is full, simply tap the cup onto the overflow pile or onto the sky area (creating a mess you will fix later).
• Why: Holding onto these cups clogs your belt. You need them gone to bring new cups up from the depths.

Triggering the Side Gates

Once Row 1 is gone, you will see the '2' Gates on the left and right sides of Row 3.

• Target: Identify the Blue cups in Row 3 that are touching these grey gates.
• Action: Clear the outer Blue cups in Row 3.
• Result: This lowers the counter on the side gates from '2' to '0'.
• Payoff: The gates shatter, giving you access to the first wave of Purple cups.

Managing the Early Purple Flow

As soon as the first Purple cups are unlocked, do not flood the sky.

• The Mistake: Players see Purple and immediately fill the top of the canvas.
• The Consequence: You ignore the excavation. The belt gets clogged because you stopped clearing the Cyan/Blue cups above.
• Correct Action: Use Purple cups sparingly. Keep the belt moving. Continue to clear the remaining Cyan/Blue cups to expose the Center Gate.

Establishing the Rhythm

Establish a rhythm of "Dig 3, Paint 1."

• For every 3 cups you clear for the purpose of unlocking a gate, only use 1 cup to actually paint the picture.
• This ensures you are constantly deepening your access into the tray rather than just using up the top layer.

Strategic Phase 2: The Center Gate Breakthrough

The middle of the board is the bottleneck. The Center Gate (Countdown '3') guards the Cream cup needed for the moon and a critical stash of Purple. This is the hardest part of the level.

Locating the Center Gate

The Center Gate is usually located in Row 2 or Row 3, directly in the middle column. It has a '3' on it.

• Guards: It is surrounded by Blue and Cyan cups.
• Lock: It sits directly on top of a Cream cup.

The "L-Shaped" Dig

To lower the counter from 3 to 0, you must clear the cups immediately adjacent to the arch.

• Step A: Clear the Blue cup to the immediate left of the gate.
• Step B: Clear the Blue cup to the immediate right of the gate.
• Step C: Clear the cup directly above the gate (or below, depending on spawn RNG).

Belt Capacity Management

This phase is where most players get stuck. Your belt (0/5) will fill up with useless Blue cups while you are waiting for the right moment to strike the Center Gate.

• The Stuck Scenario: You have 4 Blue cups on the belt. You need to clear a specific Blue cup to break the gate, but the belt is full.
• The Fix: You must "waste" a Blue cup. Tap it onto the canvas anywhere (even a completed mountain section) just to get it off the belt and spawn the next cup.

Unlocking the Moon

Once the Center Gate shatters, a Cream cup will pop up.

• Timing: Only tap this Cream cup when the Moon area on the canvas is ready to receive it.
• Warning: If your belt is full of Blue, and the Cream cup spawns at the bottom of the screen, you cannot reach it until you clear the Blue cups. If you accidentally clear the Cream cup thinking it's a "trash" cup, you lose the moon.

Transition to Flood Mode

When the Center Gate breaks, you usually gain access to the bottom of the tray.

• The bottom rows are typically 90% Purple.
• This signals the end of the "Excavation Phase" and the start of the "Painting Phase."

Optimal Fill Order and Techniques

Now that the gates are open and Purple is flowing, how do you finish the level efficiently without running out of paint? The fill order is counter-intuitive.

The Sky-First Priority

Even though the mountains are at the bottom of the picture, fill the Sky first.

• Reason: The Sky requires the most paint (Purple). If you wait until the end to do the sky, you might run out of Purple cups or have them trapped behind other cups.
• Technique: Once Purple is flowing, fill the sky to about 80% completion. Do not aim for 100% yet, just get the bulk done.

The Mountain Base

By now, you have tapped plenty of Cyan and Blue.

• Check Status: Look at the mountain range. It is likely already 60-70% full just from the "excavation" phase where you were clearing cups to break gates.
• Refining: Use the remaining Cyan and Blue cups to sharpen the edges of the mountains.
• Contrast: Ensure the Cyan (light) hits the left peaks and Blue (shadow) hits the right valleys.

The Crescent Moon Detail

The Moon is the smallest area but the highest risk.

• Precision: You usually only get 1 or 2 Cream cups.
• Action: Do not tap the Cream cup until your belt is empty and you are ready to place it precisely. A misplaced Cream pour is impossible to fix in this level due to the scarcity of the color.

Dealing with Leftovers

At the end of the game, you will have a tray full of random colors.

• Rule: You do not need to clear the tray to win. You only need to fill the canvas.
• Action: If the Sky is full, stop tapping Purple. If the Mountains are full, stop tapping Blue/Cyan.
• Winning: Let the timer run out or tap the remaining cups into a corner if the canvas is 100% full.

Advanced Troubleshooting and Speed Run Tips

This section covers what to do when things go wrong, and how to optimize for a top-tier time.

Solving "The Purple Wall"

Sometimes, despite clearing the gates, Purple cups stop coming.

• Diagnosis: You have "over-excavated." You cleared too many cups too fast, and the spawn algorithm hasn't caught up.
• Solution: Stop tapping completely for 3-5 seconds. Let the conveyor belt move naturally. Watch the tray at the bottom. If you see Purple in the mix, clear the cups directly above it to bring it up.

Recovering from Belt Clogs

A full belt (0/5) is a time killer.

• Emergency Measure: If the belt is full of Blue and you need Purple, you must find a place to dump the Blue.
• Sacrifice: It is better to overflow a small section of the mountains (making a mess) than to restart the level. Dump the Blue, get the Purple flowing, then use the Purple to cover up the Blue mess later.

Speed Running: The "Gate Focus" Method

To beat Level 107 in under 60 seconds, ignore the art completely for the first 30 seconds.

• 0:00-0:30: Tap ONLY the cups adjacent to the grey gates. Do not paint the picture. You will end up with a messy canvas, but all your gates will be broken.
• 0:30-1:00: With all Purple and Cream unlocked, switch to "Painting Mode." Fill the large areas (Sky) then details (Moon/Mountains).

Mistake to Avoid: The Premature Paint

The #1 mistake in Level 107 is trying to make the picture look pretty in the first 10 seconds.

• Why it fails: You use up the easy-access Blue/Cyan on perfect painting, leaving you with no tools to break the gates.
• Correction: Accept that the picture will look ugly (wrong colors, overflow) for the first half of the level. It will correct itself once the Purple flood begins.

Final Checklist for Victory

Before you make your final moves, check these three things:

1. Gate Status: Are all grey numbers gone? If not, keep digging.
2. Canvas Percentage: Is the sky >80% full? If not, prioritize Purple.
3. Belt Clarity: Is the belt moving freely? If yes, you are in the endgame.
