To easily gain points, w hen you complete a stage where the last two digits on the clock are the same, fireworks will go off corresponding to the number. Each firework will give you 5,000 points. Go to World 1-1 and wait until the timer hits -99, then jump on the flag. This will set off nine fireworks, giving you 45,000 points. Repeat as desired. If you get over 1,000,000,000 points, the chance of getting a Starman from a halfway powerbox increases.
