How do you get platinums on the arcade challenge things?

[AB-109]

You need to get a better time then whats specified for gold!

The times you need vary but usually it goes along with the trend eg.
Plat - 2mins
Gold - 3mins
Silver - 4mins
Bronze - 5mins

Just imagine it as an extra medal you can't see and use the pattern you can see to find out roughly what you need to get.

You can also get a list of times and strats on how to do them by just searchin at google or whatever (there are alot of sites) or try www.gamefaqs.com or http://www.mathgamehouse.com/ts2/
