I like 1, 3, 5 level subcategories to the four major categories. The other option would be fastest to X amount of points, which could be sorta fun, but relies almost ENTIRELY on RNG with the flashing bars.

You might want to include information about which exact game mode should be used, considering there are 8 game modes and the even numbered ones are two player modes. Child is 1, Slow is 3, Medium is 5 and Fast is 7.
