How to Solve Car Sort Level 451 — Full Solution
- Tap the lower-middle tower and dispatch its exposed green pair, then its blue pair, into matching visible receivers.
- Release the lower-middle red pair, let the first wave circulate, then send its cream pair as the road moves through `6/20`, `8/20`, and `10/20`.
- Complete the cream receiver and wait for its striped bar and green check before opening another four-row tower.
- Dispatch the upper-left blue and green pairs, then send its burgundy pair only after those receivers have room.
- Use the lower-left red and blue rows to complete the visible red and blue receivers.
- Release the lower-left purple and green rows one at a time, pausing at the recorded `16/20` peak until a receiver checks.
- Send the upper-middle red and purple pairs, then its brown pair after the red receiver is complete.
- Route the upper-right and lower-right green and blue pairs to the remaining green/blue receivers.
- Complete the burgundy and purple towers with the remaining same-color pairs, waiting for each completion bar.
- Dispatch the late brown pairs from the upper-right and lower-right towers as the road passes through `10/20`, `12/20`, and `6/20`.
- Stop tapping after the last brown and purple pairs enter the road, then confirm all six receiver checks and `0/20` before the win card.
Colors in this level:
Cream, Blue, Green, Burgundy, Red, Purple, Brown
Common Mistakes to Avoid
- Treating the `20` denominator as a move budget instead of shared road capacity.
- Releasing another four-row tower while mixed blue, red, green, and purple traffic is already at `16/20`.
- Mistaking a striped completion bar for a countdown and tapping again before capacity returns.
Quick Tips for Car Sort Level 451 (quick clues)
- Use a receiver's striped bar and green check as the signal that road capacity has returned.
- Hold the upper-left burgundy pair until its blue and green traffic has reached matching receivers.
- Release the final brown and purple rows only after the road has fallen from the `16/20` middle peak.
Board notes 5 details
- Layout
- Three upper and three lower four-row towers surround one clockwise rectangular road. Every cream, blue, green, burgundy, red, purple, and brown row is visible from the opening `0/20` state.
- Goal
- Complete all six same-color receivers, use each striped completion bar to recover road capacity, and let the final brown and purple cars drain to `0/20`.
- Opening
- Start from the lower-middle tower with green, blue, and red, then send its cream pair after those cars have begun entering matching receivers; the first wave reaches `6/20`, `8/20`, and `10/20`.
- Danger Zone
- Do not add another full tower at the recorded `16/20` peak. The `x/20` badge is road occupancy, not moves, and a striped bar with a green check marks a completed receiver rather than a countdown.
- Mechanics
- Six open four-row towers feed one twenty-space clockwise road; there are no question-mark covers, keys, crystals, or numbered dispatch queues in the recorded solve.
Frequently Asked Questions
What does the `x/20` counter mean on Level 451?
It is the number of cars occupying the clockwise road. The recording peaks at `16/20`; it is not a move limit.
Are any colors hidden on Level 451?
No. All six four-row towers are open from the start, so route only the visible cream, blue, green, burgundy, red, purple, and brown pairs.
What is the safe final sequence?
Complete the burgundy and purple receivers, release the remaining brown pairs, then stop tapping and let the road drain to `0/20`.
