Loop Sort – Addictive Color Sorting Puzzle Game

Loop Sort is a casual sorting puzzle game from Voodoo built around a simple idea: send cubes from trucks onto a conveyor and sort them into matching groups.

The first few levels are straightforward, but the challenge grows as the game introduces hidden blocks, curtains, ice blocks, barriers, and other obstacles. The automatic movement of the cubes means that choosing when to release each truck becomes an important part of solving the puzzle.

The result is a game that combines color matching, sorting, planning, timing, and obstacle management in a compact mobile format.

How to Play Loop Sort

The basic controls are intentionally simple:

1. Look at the trucks and colored cubes.
2. Decide which truck should be activated.
3. Tap the truck to release its cubes.
4. Watch the cubes move onto the conveyor.
5. Match cubes by color.
6. Clear groups from the line.
7. Manage obstacles blocking the path.
8. Keep enough options available for your next move.
9. Clear the entire puzzle to complete the level.

The controls are easy, but the decisions become much more complicated as you progress.

Color Sorting Gameplay

Color matching is the foundation of Loop Sort.

The goal is to organize the cubes so that matching colors can be cleared efficiently. Because cubes enter the conveyor from different trucks, the order in which you release them can make a major difference.

A move that looks useful immediately may create a problem several moves later.

That gives the game a strong planning and foresight element.

The Conveyor Belt

The conveyor is the heart of Loop Sort's gameplay.

Cubes enter the moving line and automatically progress through the sorting system. Rather than manually dragging every individual cube, you make strategic decisions about which truck to activate and when.

This creates a satisfying balance:

Tap once → Watch the cubes move → Match colors → Clear the line

The automation keeps the controls simple while leaving the puzzle-solving responsibility with the player.

Truck-Based Puzzle Mechanics

The trucks are effectively your sources of new cubes.

Before activating one, look at the colors it contains and consider how those cubes will interact with the cubes already moving through the conveyor.

This means that the best move isn't always the truck with the most immediately useful color.

Sometimes you need to wait and create the right sequence.

Hidden Blocks

Hidden Blocks conceal what is behind them.

You need to reveal what is hidden before you can continue through the level. This adds an element of discovery to the otherwise straightforward color-sorting system.

The important lesson is not to assume that the visible part of the puzzle tells you everything. Some levels require you to uncover additional information before you can determine the best route.

Curtains

Curtains create another color-based obstacle.

To lift a curtain, you must sort the required color. Once the condition is satisfied, the path opens and you can continue solving the puzzle.

Curtains therefore encourage players to pay attention to color order instead of simply clearing whichever cubes happen to be available.

Ice Blocks

Ice Blocks trap cubes behind frozen obstacles.

You need to break through the ice to free the cubes and continue the level.

This mechanic introduces a secondary objective: sometimes the key to solving the puzzle is not matching the visible cubes but figuring out how to release the cubes trapped behind the obstacle.

Barriers

Barriers prevent cubes inside from leaving while still allowing new cubes to enter.

This unusual interaction can create some interesting puzzles because the barrier changes how you manage the flow of cubes through the level.

Instead of simply asking which color should be matched next, you may need to think about which cubes should remain contained and which should enter the sorting process.

Easy to Learn, Hard to Master

Loop Sort's biggest strength is the contrast between its controls and its strategic depth.

You only need to tap a truck to start the action. But solving harder levels requires:

• Planning
• Color recognition
• Sequence management
• Foresight
• Obstacle awareness
• Resource management
• Patience

The App Store itself describes the experience as simple to play but difficult to master.

Level Progression

Loop Sort has a substantial level progression system.

Player reviews show users reaching levels in the hundreds, including players reporting progress around level 500 and level 602.

This indicates that the game is designed for long-term play rather than being a short collection of casual puzzles.

As you progress, the game expects you to recognize patterns and develop more reliable strategies for handling difficult boards.

Difficulty

Loop Sort's difficulty can vary considerably between levels.

Some players describe the game as fun and easy for long stretches, while others report difficult stages that require repeated attempts. One highly positive reviewer reached level 500 and said that harder stages required skill, planning, and foresight rather than boosters.

Another player reported becoming stuck around levels 194 and 197, describing them as particularly challenging.

This suggests that Loop Sort is not simply a reaction-based casual game. Later levels can require genuine puzzle-solving ability.

Beginner's Guide

Study the Trucks First

Before tapping, check which colors are available from each truck.

Don't Always Choose the Obvious Move

The most immediately useful color isn't necessarily the correct first move.

Watch the Conveyor

Pay attention to how the cubes move and what will happen after the next truck is activated.

Keep Future Moves in Mind

A good move should ideally create another good move afterward.

Learn the Obstacles

Each obstacle has a specific behavior. Understanding that behavior is often more valuable than memorizing individual solutions.

Repeat Difficult Levels

If a level seems impossible, try changing the order of your truck activations instead of simply repeating the same sequence.

Advanced Strategy Tips

Plan the Color Sequence

Try to determine the order in which colors need to be cleared before activating multiple trucks.

Don't Fill the Line Unnecessarily

Adding more cubes can reduce your options. Sometimes waiting is the better move.

Think Beyond One Match

A successful match should ideally improve the position of the remaining cubes.

Use Obstacles to Your Advantage

Hidden Blocks, Curtains, Ice Blocks, and Barriers aren't merely problems. They can sometimes control the flow of cubes and help structure the solution.

Memorize Successful Sequences

For particularly difficult levels, remembering the successful order of truck activations can make future attempts much easier.

Boosters and Extra Trucks

Loop Sort includes boosters and additional resources that can help players deal with difficult levels.

Current player reviews mention using extra trucks, boosters, and coins to continue through challenging stages.

However, the game does not necessarily require these resources for every level. One player who had reached level 500 specifically reported completing levels without boosters by repeating them until discovering the correct sequence.

For players who prefer pure puzzle solving, learning the level's pattern can therefore be a useful alternative to spending resources.

Coins and Rewards

Coins form part of Loop Sort's progression economy.

Players can use coins for certain additional resources, while reviews indicate that some boosters and extra trucks can require significant amounts of currency.

This has generated mixed feedback. Some players feel that rewards are too limited compared with the cost of certain resources, while the developer has acknowledged this feedback and said it would be shared with the design team.

Loop Pass

Loop Sort features a seasonal Loop Pass.

The current App Store listing promotes a new season in which players can beat levels and collect keys to unlock rewards.

This adds an additional progression track for players who want objectives beyond the standard level sequence.

Treasure Hunt

The game also features a Treasure Hunt event.

The current event asks players to compete through 10 stages while maintaining their win streak.

This gives experienced players another challenge beyond the main puzzle progression.

Game Progression System

The overall progression can be summarized as:

Choose Truck → Release Cubes → Sort Colors → Overcome Obstacles → Clear Line → Earn Rewards → Advance

As the levels become more complex, success increasingly depends on recognizing the correct sequence rather than simply tapping quickly.

Is Loop Sort Worth Playing?

If you enjoy color sorting games, conveyor puzzles, matching games, logic puzzles, and casual strategy games, Loop Sort is worth trying.

Its biggest strength is its simplicity. You don't have to learn complicated controls. Instead, the challenge comes from deciding which truck to activate and in what order.

The obstacles add another layer of depth. Hidden Blocks require discovery, Curtains require specific colors, Ice Blocks trap cubes, and Barriers change how cubes can move through the system.

The game also appears to have strong long-term appeal. Players have reported reaching levels 500 and beyond, while the current App Store listing includes seasonal events such as Loop Pass and Treasure Hunt.

The biggest concern is the progression economy. Some players believe the rewards are too small relative to the cost of boosters and extra trucks.

Still, the high 4.8/5 rating from around 14K U.S. ratings suggests that the core experience is resonating with a substantial audience.

Loop Sort vs. Traditional Color Sorting Games

Traditional color-sorting games usually involve manually moving objects between containers.

Loop Sort takes a different approach.

Cubes enter from trucks and move automatically along a conveyor, meaning your primary job is deciding when and where to introduce the next group of cubes.

This makes the game feel more like a combination of sorting and logistics.

Loop Sort vs. Match-3 Games

Match-3 games generally depend on creating combinations by swapping tiles.

Loop Sort is more about sequence and planning.

There is less emphasis on rapidly creating combinations and more emphasis on understanding how one truck activation affects the next several moves.

Loop Sort vs. Conveyor Puzzle Games

The conveyor is what gives Loop Sort its distinctive identity.

Instead of simply sorting stationary cubes, you have to work with a moving system. This creates a constant flow of information and makes timing more important.

Who Should Play Loop Sort?

Loop Sort is particularly suitable for players who enjoy:

• Color sorting games
• Cube sorting puzzles
• Conveyor belt games
• Matching puzzles
• Logic games
• Casual strategy games
• Brain games
• One-tap games
• Relaxing puzzle games
• Challenging mobile puzzles
• Obstacle-based puzzles
• Truck puzzle games
• Games with hundreds of levels

Final Verdict

Loop Sort is a polished and highly accessible color-sorting puzzle that gets considerably deeper than its one-tap controls suggest.

The concept is straightforward: tap a truck, release cubes, match colors, and clear the conveyor. But as the levels become harder, players need to think about sequence, timing, available moves, and the behavior of obstacles such as Hidden Blocks, Curtains, Ice Blocks, and Barriers.

Its large progression system is another major strength. Players have reported reaching levels well beyond 500, and the game continues to offer seasonal content through Loop Pass and Treasure Hunt.

The current 4.8/5 rating from roughly 14K U.S. App Store ratings is a strong indication that the core gameplay has broad appeal.

The main weakness is its economy. Some players feel that coins, boosters, extra trucks, and event rewards are too expensive or too limited, particularly at higher levels.

Despite that criticism, Loop Sort delivers a satisfying combination of color matching, conveyor mechanics, planning, and casual puzzle gameplay.

Overall, Loop Sort is a strong choice for players who want an easy-to-learn sorting game that gradually develops into a challenging test of sequence, strategy, and foresight.
