How to Solve Loop Sort Level 143 — Full Solution
- Release the upper green layer and let it travel through the right entry turn, around the upper hooked rail, and into the matching receiver in the middle bay row.
- Route upper purple through the same right entry turn after green clears, then send orange while keeping the middle handoff passage open between hooks.
- Release the middle pink and yellow bays only after the upper hook shows checks, routing each through the lower hooked section one colour at a time.
- Hold both large lower blue-covered trucks closed until a middle-row check exposes their matching late layer, since their traffic uses the shared right turns.
- Route gray and red through the lower hook as the right turn clears, giving each a separate pass through the bottom rail and return.
- Finish the light-blue reserve layer through the cleared lower hook and wait for all seven colour groups to check across both sections.
Colors in this level:

Common Mistakes to Avoid
- Launching lower reserve traffic before the middle handoff checks.
- Treating the upper and lower hooked sections as independent loops.
Quick Tips for Loop Sort Level 143 (spoiler-free)

Board notes 5 details
- Layout
- Two stacked hooked sections share right-side turns and a middle handoff. Three top sources feed the upper hook, while four lower reserves include two large blue-covered trucks.
- Goal
- Check seven colour groups across the upper and lower hooks as the middle bays reveal the late blue and light-blue reserve layers.
- Opening
- Release visible upper green and purple near the right entry, then route orange after the first upper check.
- Danger Zone
- The right turns and middle handoff are shared by both hooks; early lower traffic can mix green, orange, and pink in one bend.
- Mechanics
- The apparent two-box layout is one hooked route, and the large lower blue covers are controlled by the middle-row checks.
