What is the safe opening for Level 45?

Start with yellow, then use the cyan bus showing a counter around 16 to open the center.

What should I do when No spots available appears?

Stop dispatching and wait for a holding-row bus to depart before selecting the next visible color match.

The final pink-heavy tail needs a free regular bay; protect that space through the red, brown, and orange chain.

Yellow opens the multi-lobed center, followed by the cyan 16 bus. Later the row really does fill, so wait there rather than forcing another pick.

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

Dispatch the exposed yellow bus for the lower-left yellow route group.
Bring in the cyan match with the visible counter around 16 to open the central route.
Use red and brown as they become reachable, then add orange only after a regular bay is released.
Continue through green, cyan, and purple groups by visible passenger match while the multi-lobed loop contracts.
When No spots available appears, stop tapping and wait for a bus to depart.
Clear the remaining pink-heavy tail through the freed bays.

Colors in this level:

Blue, Brown, Cyan, Green, Orange, Pink, Purple, Red, Yellow

Do not dispatch another unmatched bus while No spots available is visible.
Do not occupy the center with a premature red, brown, and orange duplicate before the next exposed group is reachable.

Open yellow first, then use the cyan match around the central gap.
Treat No spots available as a wait state: let a bus depart before tapping again.
Preserve a regular bay for the final pink-heavy tail.

Board notes 5 details

Layout: A large multi-lobed route surrounds a rectangular opening. Yellow dominates the left arcs, brown fills upper inner bands, and pink and red occupy the side bends while cyan, green, orange, and purple appear through the solve. The lower queue is a large mixed field of horizontal, vertical, and diagonal buses.
Goal: Open the yellow and cyan sections, preserve the central opening through the red, brown, and orange phase, and keep a bay for the late pink tail.
Opening: Start with a yellow bus, then a cyan match showing a counter around 16. Red, brown, and orange counters around 16, 24, and 12 appear as the central route opens.
Danger Zone: No spots available appears once the regular holding row is full. Wait for a departure before dispatching another bus; premature queue additions can block the late pink route.
Mechanics: Yellow dominates the left arcs and brown the inner bands, with the late pink route held back until the end; No spots available appears when the row is full.
