How to Solve Loop Sort Level 77 — Full Solution
- Release orange from the middle-centre truck and let it cross the first right connector.
- Send pink from the middle-left stack, then route its blue and brown layers on separate passes.
- Use lower-right green and wait until it leaves the lower bend before releasing middle-right yellow.
- Open the top-right orange-red-brown-purple stack in exposed order, keeping orange and red on different circuits.
- Route revealed brown and purple cargo one colour at a time as the centre trucks turn into checks.
- Send the repeated green, yellow, and blue layers only after their receivers are visible on the next tier.
- Finish late pink, then route the exposed lower red cargo on a separate bottom-tier pass.
- Send the remaining middle-right green after red leaves the connector to complete the seventh group.
Colors in this level:

Common Mistakes to Avoid
- Launching top-right orange while middle pink or blue still occupies the upper connector.
- Treating the three S tiers as separate loops and releasing a colour into a downstream bend that is still occupied.
Quick Tips for Loop Sort Level 77 (spoiler-free)
- Let orange clear the first right connector before releasing pink.
- Separate blue and brown at the central S turn.
- Inspect the next tier after each covered green or yellow layer appears.
Board notes 5 details
- Layout
- A tall S-shaped loop has three horizontal tiers joined by alternating right and left turns. Three trucks sit above, three in the centre, and three below; visible stacks combine green, gray, purple, orange, red, brown, pink, blue, and yellow with several covered layers.
- Goal
- Complete seven group states. Early checks expose repeated green, yellow, pink, and blue cargo before the final lower red and middle-right green deliveries.
- Opening
- Send middle-centre orange first, then middle-left pink. Route blue and brown on separate turns before releasing lower-right green and the following yellow.
- Danger Zone
- The upper and lower right connectors are shared bottlenecks. Starting the top orange-red stack while middle pink/blue still rounds the upper turn interleaves two tiers of traffic.
- Mechanics
- Nine trucks feed a three-tier serpentine, so each release crosses alternating U-turns and may reach a receiver on a visually distant tier.
Frequently Asked Questions
How does the route work in Loop Sort Level 77?
It is one continuous S-shaped loop. Cubes cross alternating right and left turns between all three tiers.
Why should yellow wait behind the first green?
Both use the lower-right connector, so green must cross into the next tier before yellow can take a clean route.
