Loop Sort level guide
Loop Sort Level 221 Walkthrough
Loop Sort Level 221 is a two-rail U loop with a rightward upper rail, a left return bend, five covered upper bays, and inner trucks that expose pink, orange, green, and brown layers. Drain pink and purple first, then separate the blue/red opening from the later green, yellow, brown, red, and final gray reveals.

How to Solve Loop Sort Level 221 — Full Solution
- Tap the lower inner horizontal truck's visible pink layer and let it circulate from the inner-left entry around the upper rail and left U.
- Tap the lower-right purple bay after pink clears; wait for its check and the five upper covers to reveal their first color layers.
- Tap the lower inner truck's newly exposed orange layer, then tap the lower-left covered bay when it shows blue; let blue reach its receiver before opening red.
- Tap the lower red bay and keep its red wave behind the blue stream through the left bend while gray begins to appear at the upper-left bay.
- Tap the upper inner truck's green layer, then its orange and pink layers only after the preceding tail clears; each wave uses the same upper-right entry.
- Let the yellow wave from the upper middle/right reveals complete the lower orange truck, then route the visible yellow and pink layers from the covered upper bays.
- Release the upper inner brown layer and the brown stack revealed in the second upper bay after yellow drains through the lower return.
- Release the middle upper red layer, wait for the lower red check, then release the final upper-left gray layer and wait for every truck check and the completion card.
Colors in this level:
Green, Orange, Pink, Brown, Purple, Blue, Red, Gray, Yellow
Common Mistakes to Avoid
- Releasing the lower red bay while blue still occupies the left U-turn.
- Tapping the upper inner orange layer before its green tail has cleared the lower return.
- Treating a question-mark bay as a known color or using the `2/4`/`0/4` HUD fraction as a move count.
Quick Tips for Loop Sort Level 221 (quick clues)
- Keep the left U-turn clear between the opening blue and red waves.
- Use the upper inner truck in its observed green, orange, pink, brown order.
- Wait for the yellow and brown covered reveals before the final red and gray pass.
Board notes 5 details
- Layout
- The upper rail runs left-to-right into the upper-right gate and the lower rail returns right-to-left through the left U. Five covered bays sit above the track; the upper inner truck starts with green/orange/pink/brown, the lower inner truck starts with pink, and the bottom bank shows a covered bay, brown-over-green, red, pink, and a purple bay.
- Goal
- Finish the five upper bays, both inner horizontal trucks, and the lower bank. The upper bays reveal red/gray/blue, blue then brown, brown/pink/red/yellow, orange then gray, and green then yellow/pink; completion is all trucks checked plus the end confetti card.
- Opening
- Tap the lower inner pink truck at the inner-left entry, then the lower-right purple bay. After the upper covers reveal, tap the same inner truck for orange, then the lower-left covered bay for blue before releasing the lower red bay.
- Danger Zone
- The left U is shared by blue, red, gray, green, and yellow traffic. Releasing red before blue clears or injecting orange behind the green tail packs the bend and disrupts the receiver order.
- Mechanics
- A two-rail one-way U loop with five question-mark covered bays. Brown, yellow, pink, red, and the final gray cargo appear only after earlier color groups drain; the HUD fraction is progress, not move count.
Frequently Asked Questions
What is the first safe release in Level 221?
Tap the lower inner horizontal truck's visible pink layer, then let its pink stream clear the upper rail before the lower-right purple bay is opened.
When should red enter the loop?
After the lower-left covered bay has revealed blue and the blue wave has reached its receiver; red then follows blue around the shared left U.
What does the final covered reveal contain?
The upper-left bay eventually supplies gray. Its gray stream is the last release and completes the remaining receiver before the confetti card.
