Loop Sort Level 20 begins with blue already on the top rail. Finish blue, route upper-left yellow around the bottom, put red behind it, then open the upper-right cover for the revealed green-and-pink finish.

How to Solve Loop Sort Level 20 — Full Solution
- Let the visible blue cubes from the upper-middle source finish their top-rail receiver pass before adding another color.
- Route upper-left yellow down the right edge and along the bottom rail, leaving its left-side return clear.
- Release upper-left red only after yellow passes the left-side rise so red follows rather than overtakes it.
- Wait for the blue receiver state to change before opening the upper-right yellow-covered source.
- Send the revealed green and then pink groups around the short loop to clear both inner receivers and finish.
Colors in this level:
Blue, Yellow, Red, Green, Pink
Common Mistakes to Avoid
- Sending red while yellow is still using the lower rail and left-side rise.
- Opening the upper-right covered source before the blue receiver changes and exposes the late route.
Quick Tips for Loop Sort Level 20 (spoiler-free)
- Complete the existing blue pass before sending yellow or red.
- Keep red behind yellow at the left-side rise.
- Treat the upper-right cover as the green-and-pink endgame source.
Board notes 5 details
- Layout
- A short square loop has three top source trucks and two tall covered inner receivers. The upper-left source shows red over yellow, the upper-middle source releases blue cubes, and the upper-right source is yellow-covered. The route crosses the top rail, descends the right edge, follows the yellow bottom rail, and rises on the left.
- Goal
- Clear the six groups remaining in the recorded 4/10 state. Both covered inner receivers must complete; the board finishes only after the late green and pink traffic clears them.
- Opening
- Let blue finish its visible top-rail pass, then send upper-left yellow around the bottom. Add upper-left red only after yellow clears the left-side rise.
- Danger Zone
- Releasing upper-left red while yellow is still on the lower rail can make red overtake yellow at the shared left-side rise and delay the covered-source reveal.
- Mechanics
- Two central receivers remain covered while blue traffic passes. Their later reveal determines the green-and-pink endgame, so the upper-right yellow-covered source is held until that state changes.
Frequently Asked Questions
What should I do with the blue cubes first in Loop Sort Level 20?
Let the existing blue pass finish across the top rail. It is already occupying the route needed by the yellow and red follow-up sequence.
When is the upper-right covered source safe to open in Level 20?
Open it after the blue receiver has changed state and yellow and red have cleared their shared route. That reveal supplies the green-and-pink finish.
