Crowd Express features unique obstacles and block types that add depth and strategy to every level. Here’s a quick overview of how they work:

⏱️ Hurry

Buses move automatically after each action. You need to act quickly to avoid collisions or missing available slots.

❔ Hidden

The color of a bus remains hidden until the bus in front of it moves. Plan carefully, as you won’t know its color in advance.

🚪 Garage

The garage gate only opens for the next bus with the correct color. Sending the wrong color will not open the gate.

🔒 Lock

Locked buses cannot move for a specific number of turns. They will only become movable once the lock duration ends.

❄️ Frozen

Frozen buses are trapped in ice and cannot move. They will thaw automatically after a set number of moves.

📢 Megaphone

The megaphone instantly boards all passengers of a selected color from the queue .Use it to quickly clear or organize the waiting line.

🚍 Convoy

Convoy buses are linked together and must move as a group. The front bus must move first for the others to follow.

⛓️ Chain

Chained buses cannot move until the chain condition is met. If a chain shows a number, for example 10, you must send 10 buses to the parking area to break it and release the bus.

🍬 Gum

Gummed buses stick together and must enter a slot at the same time. They cannot be separated once attached.

🔑 Key

A key is required to unlock the bus. Until the key is collected, the bus cannot move.

🚦 Transit

Transit buses arrive already filled with mixed passengers. You must sort the passengers by color before proceeding.

🎨 Dye

Dye buses permanently paint their parking slot with their own color. The slot remains that color for the rest of the level.

📈 Overload

Lanes and slots have capacity limits. If you exceed the limit, the lane becomes blocked and traffic stops.

🦶 Kick Out

Some slots will eject a parked bus after a short time. Move or clear the bus before it is kicked out.

💣 Bomb

Bomb buses have a countdown timer. You must clear the matching bus before the timer ends to avoid penalties.

🟧 Cone

Traffic cones block entry from specific directions. You must remove the cone or find an alternate route.

🪜 Platform

Platforms shift or carry buses when aligned correctly. Timing is important to cross or ride them safely.

🔄 Rotate Bus

Rotate buses change their facing direction after each move. Align them with the exit before sending them forward.

💩 Mud

Mud tiles trap the first bus that drives over them, freezing it in place. The mud is consumed after one use, allowing the bus to move again afterward.

⚡ Shock

Shock buses temporarily disable all buses of the same color. That color becomes unmovable for one turn.

📦 Wrap

Wrapped buses toggle between open and closed states with every move. They can only be interacted with while open.

🙈 Cover

Covers hide the passenger queue and block visibility. You must remember the order of passengers to plan correctly.

⏩ Conveyor

Conveyor belts shift everything on them one tile in the shown direction after each move. Plan ahead to avoid unwanted repositioning.

🅿️ Slotter

Slotter buses provide a temporary advantage. When sent to the waiting area, they grant +1 additional slot.

🚜 Scoop

Snow piles block roads and prevent movement. Only buses with a scoop can clear the snow and open the path.

🧲 Magnetic

Magnetic buses stick when they collide with another vehicle.. Instead of returning to their starting position, they stop and remain attached.

Each obstacle introduces a new challenge. Understanding how they work will help you develop the right strategy to clear tough levels.
