How to Play Loop Sort

To play Loop Sort, tap a truck to release cubes and observe where they settle. Choose the next truck by looking at which groups are still unfinished and what the newly exposed cargo lets you do.

Read the board before moving

Find the level number and look at the whole track. Note whether the route is a compact loop or winds around multiple sets of trucks. Identify which trucks expose cargo and which are covered. At this stage you only need enough information to make the first useful choice. Pick out one color that is easy to follow and one place where it can move. If a number or symbol is visible on an obstacle, keep it in mind and check how it changes after a successful sort. This gives you a direct way to distinguish a useful release from one that simply adds more motion.

Watch one release from beginning to end

Tap an available truck once and follow the cubes onto the conveyor. Watch the first group that accepts cubes and then see where the remaining cubes travel. Wait for the relevant animation before choosing another truck. The moving track provides feedback about the last choice. A truck that now shows a completion mark represents a finished group. A truck that still holds only part of a color may need a later release. Look again at the source truck once its visible cargo has moved. The next exposed cubes can make a previously awkward choice easier to handle.

Work from unfinished groups

Imagine each unfinished group as a destination with limited room. On a board with several similar colors, compare both the hue and truck position. One group can be close to completion while another still needs most of its cargo. If a release can finish the first group without piling extra colors onto the loop, watch it through and take stock after the space changes. When you cannot see a useful destination for a color, inspect a different exposed truck. A move can be available to tap and still use the room you need for something else.

Open a curtain when its color is ready

Look at the color marker on the curtain and find where that color is exposed elsewhere on the board. Follow the cubes during the match and observe the curtain afterward. When a cover lifts, stop and read the cargo below it. That revealed truck may contain another color you need or a mixed load that requires more room. If a walkthrough opens a curtain earlier than you did, compare the releases leading up to that moment. Copying the later tap sequence while the curtain is still closed can send cubes toward a destination that your current board cannot use yet.

Treat hidden cargo as new information

With a covered truck or a masked layer, you can act on the visible part of the puzzle and then revise your plan. Keep one useful source in reserve if you have a choice so that the next revealed color has a way forward. Use the same approach for ice. Identify which cargo is currently free, observe changes to the frozen area after sorting, and read the newly available cubes before tapping it. On a board with a directional barrier, trace the allowed approach and check which side holds the pieces you want to release. The same route can give access in one direction while holding cubes in place from the other.

Track progress when the route is long

On a winding track it can be hard to tell which tap caused a later change. Watch a distinct color until it enters a truck or returns around the loop. Then check the front and far side of the route for new groups. A useful pause point comes just after a truck finishes, a cover lifts or a layer is revealed. Use that moment to choose a new local goal. For example, compare the only visible source of a curtain color against the truck that is already partly sorted. The important relationship is between what can enter the loop and where it can finish.

End a run or inspect a retry

Continue until the board clears or the app presents a retry or continuation prompt. Read the prompt for your run before spending a reward or accepting an offer. If you return to the starting board, remember the first place the route backed up or a needed truck became inaccessible. Change the tap that led to that situation and watch the response. A video is easiest to use when you play one visible decision at a time. Pause when the camera shows a new layer, compare that layer with your own board, and resume once you know the next destination. If two groups remain, pick one and follow its color past the nearest bend. This can help you see whether it reaches its destination or keeps circulating while the other group takes up the available room. By the end, check for the last unfinished group rather than assuming that a mostly empty track means the puzzle has cleared.
