The surfaces. Same bike and the same controls, but ice and snow change how the wheels behave, so lines that worked on tarmac need adjusting rather than relearning from scratch.

Moto Traffic Rider. It swaps obstacle courses for moving traffic, so the skill becomes reading gaps at speed rather than timing rotations in the air.

Yes. They all run free in your browser with no download and no account, so you can restart a course as many times as it takes.
