In Roof Rails Online, you get to be a super cool runner balancing on super high roofs! You slide across railings, collecting colorful planks to make your path longer and jump from one roof to another. Watch out for gaps because if you fall, you have to start again! You can race against your friends or other players from all over the world. The fun part is making the longest bridge and zooming across rooftops while trying not to tumble. It's all about speed and balance, and you can show off your best moves! Let’s see who can reach the finish first!
