When you finish the 6th race, a victory screen appears containing many
multicolored marbles rolling everywhere against a black backdrop. It says
"Congratulations left player [or "right player" if player 2 won] you have
completed the ultimate race!" Below this, it calculates your points (based
on a bonus for finishing, a bonus for remaining seconds on the clock, and a
deduction for number of times you died) and adds this to your total score.
You then get a chance to see your name listed on the High Rollers list, after
which the game resets.
