A standard entry offers the highest payouts, but you need to get all your player selections correct to win.
If even one selection is wrong, you lose the total amount you put into the wager. It's a high-risk, high-reward play. For example, a 10-player selection with a standard play gives you 300X the money you put in.
For a standard entry, these are the corresponding payouts.
2 player selections → 3X
3 player selections → 5X
4 player selections → 10X
5 player selections → 20X
6 player selections → 30X
7 player selections → 50X
8 player selections → 100X
9 player selections → 175X
10 player selections → 300X
11 player selections → 500X
12 player selections → 1000X
