Where are the three keys on Level 493?

Purple is on the opening yellow pair, pink is in the lower-right stack, and green is at the top-left stack.

Which key should be used first?

Use purple first because it is already on the road, then pink, and finally green as their stacks become reachable.

No. It is live road occupancy and later rises as high as `14/16`.

Car Sort Level 493 wraps a sixteen-space road around three chained receivers unlocked by a purple road key, a lower pink key, and an upper green key.

If the player asks you to sign in, open the video on YouTube instead.

From `2/16`, route the yellow pair carrying the purple key to its receiver.
After the purple chain disappears, sort the exposed blue traffic from the right tower.
Send visible red and green road pairs into open receivers.
Build the horizontal lime receiver before exposing another lower row.
Work through the lower-right burgundy/blue stack until the pink key appears.
Route the pink-key car and open the pink-locked center tower.
Clear the revealed red and later purple/burgundy rows from that tower.
Complete yellow above and blue below while occupancy stays under `14/16`.
Reach the green key at the top-left cyan stack without mixing its supporting rows.
Use the green key to remove the last central chain.
Fill the opened pink, purple, and burgundy central groups in order.
Complete top orange, green, yellow and bottom red, cyan, blue.
Let the final pink, cyan, and orange road traffic drain around the square.

Colors in this level:

Yellow, Purple, Blue, Red, Green, Lime, Pink, Burgundy, Cyan, Orange

Board notes 5 details

Layout: Three top and three bottom towers surround three chained central towers plus a horizontal lime receiver; occupancy opens at `2/16`.
Goal: Use the purple, pink, and green keys in reachable order, clearing each unlocked receiver before pursuing the next key.
Opening: Route the opening yellow pair carrying the purple key immediately so the right central chain unlocks.
Danger Zone: The road reaches `14/16`; opening unrelated covered rows before using an available key can strand several colors around the square.
Mechanics: Purple, pink, and green keys directly unlock matching central padlocks; no numbered source or completion countdown is present.
