In international club football, the Big Green has won the first ever international tournament known as Copa Rio in 1951, the 1999, 2024 and 2024 Copa Libertadores, the 2024 Recopa Sudamericana, and the 1998 Copa Mercosul.

When you see the odds presented as 30:1 or 3:1 that's actually just showing the payout for a winning bet, not the likelihood of that team winning. 30:1 doesn't mean that the team is 30x more likely to win, it means that if you bet on that team and they win you will receive $30 for every dollar you bet.

On a machine that pays 31-for-1, the machine keeps your bet when you make it, but pays 31 units on a win  still a total of 31 on your side after a win. So 31-for-1 is the same as 30-to-1, 16-for-1 is the same as 15-to-1, 10-for-1 is the same as 9-to-1, and so on.
