Car Sort Level 420 Walkthrough

How to Solve Car Sort Level 420 — Full Solution
- Let the opening 12/14 traffic circulate; green cars enter the center-left top column and the first green checkmark appears.
- Route cyan from the first spine shelf into the top-tier road and confirm its receiver check as the crystal 4 steps to 3.
- Dispatch the yellow pair from the center-right top column's upper row and route it through the right turn.
- Send the blue/cyan pair from the second spine shelf, letting it drain toward the blue receiver while occupancy falls toward 10/14.
- Release the green and pink pairs from the fourth spine shelf; green enters the center-left top column and pink checks the first middle receiver.
- Complete the center-left green column and confirm the crystal 3 steps to 2 after the qualifying checks.
- Tap the cyan pair from the first spine shelf's revealed lower layer and route it to the cyan receiver on the right.
- Open the lower-left crystal 2 gate after its two qualifying completions; release the patterned wavy group and wait for it to resolve into solid-color cars.
- Route the revealed red cars from the lower-left box into the left top column, filling its lower rows beneath the dark-red pair.
- Send the blue pair from the second spine shelf's revealed lower layer into the blue/cyan receiver and confirm its check.
- Dispatch the green pair revealed on the fourth shelf's second layer and let it complete the green spine receiver.
- Release the dark-red/burgundy pair from the left top column's bottom row after the red cars above it are checked.
- Route the purple pair from the right top column into the upper-right receiver and confirm the crystal 1 steps toward clearing.
- Open the gated fifth shelf on the spine after crystal 1 clears; release its cyan/light-blue group one pair at a time.
- Send the orange pair from the right top column's bottom row into the orange receiver.
- Complete the purple column by routing the remaining purple traffic from the lower-left box's second reveal.
- Fill the cyan/light-blue spine receiver and confirm its checkmark while the road falls from 10/14 toward 6/14.
- Route the late dark-red/burgundy group from the lower-left box's final layer into the bottom spine receiver.
- Release the last green and orange cars circling the lower exit and let the road drain from 6/14 through 4/14 to 0/14.
- Stop tapping and confirm every receiver checkmark and the Level Completed card.
Colors in this level:

Common Mistakes to Avoid
- Tapping the lower-left patterned box before the crystal 2 gate has cleared after two receiver completions.
- Releasing a spine shelf's hidden layer at 12/14 or 14/14 while the right vertical lane is full.
- Treating the crystal cylinder numerals as move limits or tappable dispatch queues.
Quick Tips for Car Sort Level 420 (quick clues)
- Let the crystal 2 gate clear before tapping the lower-left patterned box; two receiver completions must happen first.
- Watch for the green checkmark on each spine shelf before opening the next hidden row below it.
- At 12/14 or 14/14, stop tapping and let the L-road drain through the lower-left exit.
Board notes 5 details
- Layout
- A fourteen-space L-shaped road runs across the top, turns down the right side, and exits at the lower-left. Four wide receiver columns sit across the top (initially patterned/yellow/dark-red, empty, yellow/blue-patterned, and patterned/purple/orange). A vertical source spine of five shelves occupies the right-center with cyan, blue, green/pink, and hidden rows. Four crystal cylinders (2 at lower-left, 1/3/4 stacked on the right) gate the lower-left box and spine reveals.
- Goal
- Fill the four top columns as red, green, yellow, and purple; complete the five spine receivers as pink, blue/cyan, green, cyan/light-blue, and the late dark-red row; clear the gated lower-left source; and drain the road to 0/14.
- Opening
- The video opens at 12/14 with green, cyan, blue, red, and yellow already circling. The first visible dispatches route green into the center-left top column and cyan through the first spine shelf, earning the first receiver checks and stepping the crystal 4 toward 3.
- Danger Zone
- The road hits 12/14 and 14/14 when the lower-left patterned box opens while the vertical spine is still draining. Tapping behind the crystal 1 gate before it clears strands purple and dark-red cars without receivers.
- Mechanics
- Four crystal countdown cylinders (2, 1, 3, 4) are completion-driven gates that reduce as matching receivers check. Question-mark covers hide real colors on the spine and lower-left box. x/14 is road occupancy, not a move limit.
Frequently Asked Questions
What do the four crystal cylinders do on Level 420?
They are completion-driven countdown gates numbered 2, 1, 3, and 4. Each reduces when matching receivers check off. The lower-left 2 gates the patterned source box, and the right-side 1/3/4 gate successive spine shelf reveals.
Is 14 a move limit?
No. The x/14 badge is live road occupancy on the shared L-road; no move limit is shown in the video, so moves remains null.
When does the lower-left source box open?
After the crystal 2 cylinder clears, which requires two qualifying receiver completions. Only then can the patterned wavy group be tapped and its solid colors revealed.
