How to Solve Loop Sort Level 31 — Full Solution
- Tap the left-middle orange exposure and let it clear the upper and right sections of the square loop.
- Release the visible red group only after orange has passed the top bend, then let red reach its matching upper stack.
- Send cyan and pink middle exposures one clear lap at a time; do not open the second red source during the first red delivery.
- When the center trucks become checked, route the newly exposed lower pink and green blocks through the cleared loop.
- Finish the remaining cyan and red cleanup groups and wait for the final lower truck to check off.
Colors in this level:
Yellow, Red, Gray, Purple, Pink, Orange, Blue, Cyan, Green
Common Mistakes to Avoid
- Opening the red-pink source while the earlier red group is still moving across the top rail.
- Treating a checked center truck as a new live target instead of the cue to inspect the lower row.
Quick Tips for Loop Sort Level 31 (spoiler-free)
- Give orange and the first red separate passes through the top bend.
- Wait for a middle check mark before changing to the lower row.
- Keep the second red source closed until the first red group has resolved.
Board notes 5 details
- Layout
- A compact rounded square loop surrounds four horizontal center trucks. Top stacks visibly show yellow-red, red-gray, gray-yellow, and purple-pink layers; the center row exposes orange-blue, red-cyan, red-pink, and cyan-orange loads above covered lower trucks.
- Goal
- Complete seven groups. The early middle trucks turn into check marks, then the lower area exposes pink, green, cyan, and red groups before the empty outer loop confirms completion.
- Opening
- Send the left-middle orange group first and let it clear the upper/right side. Start the visible red route only after orange has passed the top bend.
- Danger Zone
- Opening the red-pink middle truck while the first red still uses the top rail puts both red routes into the compact loop's only useful buffer.
- Mechanics
- Center completions are progression signals. Checked middle trucks reveal the late lower cleanup colors rather than creating fresh receiver slots.
Frequently Asked Questions
What is the safest first color in Loop Sort Level 31?
Start with orange from the left-middle truck. It clears the shared top/right path before the first red group needs it.
When should I use the lower trucks in Level 31?
Wait until the middle trucks visibly become checks. Their completion exposes the late pink, green, cyan, and red cleanup state.
