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. Act fast to avoid collisions or missed slots.

  • Hidden: A bus’s color stays hidden until the bus in front moves.

  • 🚪 Garage: The gate only opens for the next bus of the correct color.

  • 🔒 Lock: A bus is locked for X turns and won’t move until the lock is lifted.

  • ❄️ Frozen: A bus is stuck in ice and won’t thaw for a set number of moves.

  • 📢 Megaphone: Instantly boards all passengers of a chosen color from the queue.

  • 🚍 Convoy: Linked vehicles move together — the one in front must go first.

  • ⛓️ Chain: Chained buses won’t move until the chain is broken.

  • 🍬 Gum: Gummed buses stick together and must enter the slot at the same time.

  • 🔑 Key: A key is required to unlock this bus before it can move.

  • 🚦 Transit: A bus arrives already filled with mixed passengers — sort them by color.

  • 🎨 Dye: A special bus paints its parking slot in its own color for the rest of the level.

  • 📈 Overload: Lanes/slots have capacity limits — if you push past them, the lane blocks and flow stalls. Manage traffic to avoid overflow.

  • 🦶 Kick Out: Certain slots will eject a parked bus after a short window. Clear or move it before it’s kicked out.

  • 💣 Bomb: Clear the matching bus before the countdown ends to avoid penalties.

  • 🟧 Cone: Traffic cones block entry from specific directions. Remove or route around them to proceed.

  • 🪜 Platform: Platforms carry or shift buses when aligned. Time your moves to ride or cross them safely.

  • 🔄 Rotate Bus: This bus rotates its facing after moves. Align its direction with the exit before sending it.

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