How to Solve Loop Sort Level 489 — Full Solution
- Tap upper source 1 on yellow; it enters from the upper-left, checks, and leaves light blue visible there.
- Tap inner source 1 on light blue; it enters the inner rectangle, checks, and exposes brown in I1.
- Tap inner source 4 on red; the receiver checks and exposes yellow there.
- Tap inner source 2 on orange; its check exposes red in the same inner bay.
- Tap inner source 3 on light blue; it checks and exposes orange there.
- Tap upper source 1 on light blue; the check clears U1 and releases the first upper curtain.
- Tap upper source 5 on orange; orange checks and exposes red above it.
- Tap U5 on red; the red check exposes gray at that right edge.
- Tap U5 on gray; the gray receiver checks and the right upper curtain retracts to reveal U4.
- Tap newly revealed U4 on green; its check exposes a second green face and retracts the adjacent upper curtain.
- Tap newly revealed U3 on orange; the orange receiver checks and exposes green there.
- Tap I2 on red; this separate inner red checks and leaves I2 empty.
- Tap I4 on yellow; its check clears I4 and opens the first lower curtain position.
- Tap I3 on orange; the orange receiver checks and exposes pink beneath it.
- Tap I3 on pink; its check exposes the next covered face in that inner source.
- Tap U2 on pink after the upper curtain reveal; pink checks and exposes its covered/gray face.
- Tap U3 on green; the green receiver checks and clears that upper source.
- Tap U4 on the second green face; its check clears U4 and allows another lower curtain to retract.
- Tap lower source 5 on green; it checks and exposes purple above the next covered face.
- Tap L5 on purple; the purple receiver checks and exposes light blue there.
- Tap lower source 4 on brown; the brown receiver checks and reveals another brown face.
- Tap L4 on brown again; the second brown check clears that source.
- Tap lower source 3 on pink; its check exposes gray underneath.
- Tap L3 on gray; the gray receiver checks and clears L3.
- Tap lower source 2 on white; keep this white truck isolated until the white receiver checks and a dark face is exposed elsewhere.
- Tap lower source 1 on black; this is a separate tap and receiver from white, and the black check clears L1.
- Tap U2 on its remaining pink face; the pink receiver checks and clears U2.
- Tap L5 on light blue; its check clears the rightmost lower source.
- Tap upper source 4 on green, the first of the last three taps; it feeds the matching inner source 3 receiver, checks, and exposes light blue at U4.
- Tap inner source 3 on the received green face, the second-last tap; the green receiver checks and clears I3.
- Tap upper source 4 on the revealed light-blue face; the final truck checks, the HUD returns to 0/5, and the Loop Sort confetti/logo follows.
Colors in this level:
Light blue, Blue, Yellow, Orange, Red, Brown, Pink, Purple, Green, White, Black, Gray
Common Mistakes to Avoid
- Assuming the mirrored curtains reveal matching color orders.
- Filling all four corners with orange, red, and pink traffic.
- Releasing the final light-blue stack before green exits the inner rectangle.
Quick Tips for Loop Sort Level 489 (quick clues)
- Inspect the exposed face instead of mirroring the previous curtain row's order.
- Keep orange/red separate from newly revealed pink and green.
- Leave the last light-blue upright stack for the open perimeter.
Board notes 5 details
- Layout
- A compact rectangular loop surrounds four inner trucks while curtain-covered reserves mirror each other above and below the perimeter.
- Goal
- Open every mirrored curtain position and empty each upper, inner, and lower source; the HUD fraction changes with circulating trucks and returns to 0/5 after the final light-blue check.
- Opening
- Send light blue and yellow separately, then route brown and red to expose orange, pink, purple, and green reserves.
- Danger Zone
- Mixing inner orange/red traffic with newly revealed pink or green occupies every corner and delays the lower curtain row.
- Mechanics
- Mirrored curtains feed the short loop from both sides, and the endgame leaves green inside while a last light-blue stack feeds the outer edge.
Frequently Asked Questions
Do the mirrored curtains reveal matching color orders?
No. Inspect the newly exposed face after each curtain retracts instead of copying the opposite row.
When can the last light-blue stack be released?
After green has left the inner rectangle; releasing it earlier occupies the outer edge while green still needs the compact loop.
