How to Solve Loop Sort Level 309 — Full Solution
- Route the upper center yellow stack, then the upper-right orange and gray layers after the top-right corner clears.
- Clear the upper-left green/orange layers and wait for the first two curtains to retract.
- Work across the inner top row through its blue/red, orange/blue, and red/green bands.
- Route the inner lower pink/light-blue and green/red trucks while the bottom reserve remains covered.
- After the bottom curtain retracts, alternate its light-blue, brown, orange, green, and pink faces with open inner receivers.
- Finish the late brown/red, solid red, green/blue, and pink layers until all three tiers are checked.

Quick Tips for Loop Sort Level 309 (quick clues)
- Use upper yellow and orange/gray checks to open the interior before touching the lower curtain.
- Alternate inner and lower tiers when their visible colors share an open receiver.
- Keep the right rail clear before sending late red, green, or light-blue waves.
Board notes 5 details
- Layout
- Three exposed vertical trucks sit above a square loop, two red curtains cover the interior, and a third curtain hides most of the lower trio. Checks uncover a three-by-two inner grid and the late lower reserve.
- Goal
- Clear all three source tiers through the same four corners until the upper trio, six inner trucks, and lower trio all show checks.
- Opening
- Drain the upper yellow stack, then the upper-right orange/gray and upper-left green/orange layers to retract the first curtains.
- Danger Zone
- Inner red or blue traffic can occupy the right rail when the lower green/light-blue reserve opens; a covered tier provides no color evidence.
- Mechanics
- Three progressive red curtains, three source tiers, a six-truck inner grid, and a SUPER HARD label stage alternating upper, inner, and lower releases around one square.
Frequently Asked Questions
Which stack opens Level 309?
The upper center yellow stack, followed by the upper-right orange/gray and upper-left green/orange layers as the top corners clear.
Why alternate between the inner and lower tiers?
A curtain check can expose a lower color whose receiver is already ready; clearing it immediately preserves space on the single square loop.
