How to Beat Bus Fever Party Level 78
To beat level 78, start with the free buses on the outside, uncover the dark question-mark buses one at a time, and park only buses whose color the queue needs next. The dark buses hide their color until the road in front of them opens, so clear their approach early and keep a grey spot free for what comes out.
The lot holds about 35 buses. Three long buses lie across the top, short vertical buses stand in a line below them, and two rows of dark buses fill the middle above a dense group at the bottom.
| Waiting spots | VIP spot on the left, then grey spots, then green extra spots with a plus on the right |
|---|---|
| Buses at the start | about 35, in about 8 colors, plus hidden buses |
| Garages | none |
| Densest area | the center: two rows of dark question-mark buses with a packed group below them |
| Boosters on screen | VIP, Arrange, Jumble |
Dark Buses in the Middle
Look at the center first. Two rows of dark buses with a white question mark sit side by side there. A dark bus does not show its color until the path in front of it is clear, so you cannot plan around it at the start.
The edges are friendlier. Three long buses lie along the top with arrows pointing left, and the left and right sides have buses with free arrows. A short vertical bus stands alone at the top right. Below the dark rows is a packed group where the buses block each other.
Both the colors of buses and passengers are mixed up between runs, but each bus keeps its position and arrow. Your colors may differ from the screenshots, but the order by position works with any colors.
Level 78 Walkthrough Step by Step
-
Send out the free edges. Begin with the long buses at the top and the buses on the side columns, since their arrows point at open road. Soon the waiting row is almost full, and the message No spots available shows up when you tap with no free spot. The first dark buses to open often show a color you have not seen on the lot yet.

Video solution for level 78
This video runs through level 78 from start to finish. The colors in it may not be yours, so rely on where each bus stands.
-
Clear the top row. The long buses on top are gone now. Under them stands a line of short vertical buses that lock one another, so take them one at a time. Four buses are parked in the row, and each of them needs its passengers before you add another.

-
Uncover the dark buses. As the lines above the dark rows thin out, the question marks start to open. Each uncovered bus shows its color before it leaves, so you can decide whether to park it now. Do not take a hidden bus just to see what it is.

-
Open the middle. Now only one bus remains at the top right, and the dark rows stand on their own. Free the buses beside them, so their path opens one by one. Spots are limited here, so park a bus only when its passengers are near the head of the queue.

-
Finish the dark rows. The dark buses leave one after another and the middle empties. Only a single dark bus and a short bus beside it are left in the upper half. Three buses sit in the row and are filling, which leaves you room.

-
Take the bottom group. The last group sits at the bottom of the lot. Release its buses along the arrows, beginning with those that have a free path, and park the one the queue needs next. When the last bus fills, the level is cleared.

Why Level 78 Locks Up
The level locks up when all the grey spots hold buses that the queue does not need yet. The warning No spots available then blocks your taps until a parked bus fills and leaves. Hidden buses make this worse, because you cannot tell their color before you uncover them. When the row is nearly full, stop and wait until a parked bus leaves, then tap again. Tapping a locked or unneeded bus at that moment gains nothing, while a pause lets the parked buses board and free a spot. Do this each time the message appears, and tap again only after a bus has left the row. When a run stalls on this level, start over and plan the first five taps with more care; that is quicker than fighting a full row.
The second problem is the center. While the dark buses stay closed, you cannot see what is coming, and one wasted spot can cost the run. Open their approach with one or two exits at a time, and clear the vertical buses under the top row in turn rather than all at once, since they lock several arrows together.
Frequently Asked Questions
What do the dark buses with a question mark mean?
They are buses whose color is hidden. The color appears once the path in front of the bus is clear, so you see it before the bus leaves. Until then you cannot plan around it, which is why you should open their approach early and keep a spot free.
Why do the colors on my screen not match the screenshots?
The layout and arrows of level 78 are the same for everyone, but the colors of buses and passengers are shuffled between runs. Follow the steps by position: free edges, the top row, the dark rows, and the bottom group last.
What should I tap first on level 78?
The three long buses at the top and the buses on the side columns. Their arrows point at open road, so they park at once. Pick the ones the queue needs, and leave the dark rows alone until their approach is open.
What does the No spots available message mean?
It means every waiting spot is taken, so your tap does nothing. Let a parked bus board its passengers and drive off to free a spot. If none of them can fill soon, the game offers an extra spot for coins or an ad, or you can restart.
How many buses are on level 78?
About 35, in about eight colors, with two rows of dark question-mark buses among them. There are no garages. Most of the difficulty comes from the hidden colors in the center and from the packed group below them.
