- Tap M1 for the brown block exposed at that same coordinate.
- Tap L1 for its one green block and wait until it reaches the outside descent.
- Tap the gray cargo card at M2.
- Tap the gray cargo card visible at L1; the gray receiver checks automatically.
- Tap the pink cargo card at L1; it fills H2's empty cell and the pink receiver checks automatically.
- Tap the green cargo card at L2.
- Tap the light-blue cargo card at M2.
- Tap the light-blue cargo card at L2.
- Tap the pink cargo card at T3.
- Tap the two-block purple cargo card at T4.
- Tap the orange cargo card at T2.
- Tap the orange cargo card exposed at T4.
- Tap the brown cargo card exposed at T4.
- Tap the brown cargo card at M1.
- Tap the purple cargo card exposed at T2.
- Tap the blue cargo card exposed at T3.
- Tap the gray cargo card exposed at M2.
- Tap the bottom yellow cargo card at T1.
- Tap the yellow cargo card at L2.
- Tap the next brown cargo card at M1.
- Tap the brown cargo card now exposed at T1.

Common Mistakes to Avoid
- Opening the top-left yellow/red tower instead of clearing the inner orange and brown layers.
- Treating the wide lower-right red/pink receiver rows as tappable sources.
- Starting late red before gray, blue, pink, and purple traffic has left the inner loop.
Quick Tips for Loop Sort Level 520 (quick clues)
- Open from the inside out: M1 orange, M1 brown, lower-left green.
- Pair gray at M2 with gray at L1 before the pink and purple phase.
- Save T1 red and yellow until horizontal H1 and H2 have cleared.
Board notes 5 details
- Layout
- T1-T4, M1-M2, L1-L2, and H1-H2 surround the spiral. T1 has yellow/red/brown/yellow; T4 brown/orange/two purple; L1 brown/green/pink; L2 light blue/green/yellow; H1 has three red blocks and H2 two pink.
- Goal
- Open circulation with M1, feed early gray through M2/L1, clear fixed H1-H2 red/pink receivers, and finish yellow at T1/L2 followed by green at L2.
- Opening
- Tap M1 orange, the brown block exposed at M1, and then the one green block at L1.
- Danger Zone
- The four-block T1 tower is late because its yellow receiver at L2 is under light blue/green and its red block competes with three-block H1.
- Mechanics
- The tall route combines an inner loop with a long outer descent. H1 starts with three red cells and H2 with two pink cells; incoming cargo fills each empty cell and the passive receiver row checks automatically without a tap.
Frequently Asked Questions
Are the wide H1 and H2 blocks obstacles in Level 520?
No. H1 is a three-block red receiver and H2 is a two-block pink receiver; both behave like normal stacks.
Which source completes Level 520?
The final lower-left green reserve checks after the late yellow route, completing all four groups.
