Your goal is to build the path for the bus to reach the end of the road! You'll get a few seconds to start building the road before the bus starts moving. On the bottom of the screen, you can choose from one of two tiles. Click on the tile you want and then drag it onto the map to place it. The square in each bottom corner tells you which piece will come next if you choose the current one.

If you haven't finished your path once the bus starts driving, it's okay! You'll still have time to build your path so long as the bus doesn't drive over the path. Once a bus drives over a tile, that road will turn white and you won't be able to move that tile. If you do replace one tile with another that hasn't been driven over, however, you will lose 50 points from your total score.

There are special tiles you can use that can grant bonus points. When you place the crossroad tile, it's important to note that the bus will drive in the current direction it's facing. For example, if it's driving horizontally, it will continue to move horizontally until another tile turns it. There's also roundabouts, which are yellow tiles on the map. A tile with a green icon is a metal tile and can only be a corner tile. A tile with an orange icon is a one way tile - you can only move in the direction the arrows are facing on those tiles. Purple tiles are teleportation tiles - you drive through one, you'll drive out of the other teleportation tile!

There are also some tiles you want to avoid! Blue tiles are water tiles, and you can't drive over those or place tiles on top of them.

Each level has a goal road length that is on the bottom of the screen. If you reach the goal early, you can click the STOP sign and earn double points!
