How to Solve Loop Sort Level 172 — Full Solution
- Tap the lower row third bay and release its visible pink batch into the lower-left loop entry; let pink travel clockwise along the bottom and right rails.
- Tap the lower second bay for its exposed light-blue/purple stack; let the pale-blue wave enter behind pink and wait for its check state.
- Tap the lower-left bay for its visible orange layer and the green layer revealed beneath it; both use the lower-left entry.
- Tap the lower-right green/blue bay, then the neighboring yellow-reveal bay when the lower row exposes its next visible slab; do not add a covered top stack while these waves cross the bottom rail.
- Tap the far-right top bay for its exposed yellow layer, then release the red layer revealed in that same bay after yellow circulates and the receiver checks.
- Tap the far-left top bay when its gray layer becomes visible, sending the gray group through the left entry.
- Release the newly exposed upper blue and brown groups in the video order, waiting for the matching top or lower receiver to check after each wave.
- Return to the remaining lower pink/light-blue bays as their covers lift, routing the remaining blue/gray mix without opening an unseen upper cargo stack prematurely.
- Finish with the upper-middle orange group and the last gray/blue receiver state; the final orange stream empties the rectangle and all top and bottom bays check.
Colors in this level:
Red, Blue, Light-blue, Orange, Pink, Green, Yellow, Gray, Purple, Brown
Common Mistakes to Avoid
- Tapping an upper covered bay before the lower pink/light-blue sequence has settled.
- Treating a patterned top face as a known color or treating the header fraction as a move count.
Quick Tips for Loop Sort Level 172 (quick clues)
- Use the lower pink and light-blue sources first; they establish the first clockwise return.
- After a lower bay checks, read its newly exposed neighbor or upper reveal before adding another covered source.
- Hold the final upper orange group until the gray/blue receiver state is visible.
Board notes 5 details
- Layout
- A compact clockwise rounded rectangle has five covered top bays with red, blue, orange, blue, and pink faces, plus five lower bays showing orange/green, pink/light-blue/purple, pink, yellow, and green faces from left to right.
- Goal
- Resolve the six target groups across both rows, keeping checked lower bays closed as receivers. Completion is every active bay checked, an empty loop, and the Loop Sort celebration rather than the header cube fraction.
- Opening
- Tap the lower third pink bay, then the lower second light-blue/purple bay; route both through the lower-left entry before opening the lower-left orange/green supply.
- Danger Zone
- The upper row is covered at the opening. Tapping the upper orange or far-right red-reveal bay while lower pink and light-blue traffic still fills the bottom return would mix a new color into the horizontal receiver order.
- Mechanics
- Two-sided multi-bay routing with covered upper cargo, lower-first opening traffic, and progressive gray/yellow/red/blue/orange reveals around one one-way loop.
Frequently Asked Questions
Which row opens first in Level 172?
The lower row opens first: the video starts with the third pink bay, then the second light-blue/purple bay.
How should upper covered bays be read?
Wait for a lower check or release to expose the actual red, gray, yellow, blue, brown, or orange face before tapping it.
What is the final cue?
The upper-middle orange stream drains the loop, every active bay shows a check mark, and the Loop Sort celebration appears.
