SAN ANTONIO -

The rush is on for Mega Millions lottery tickets.

The jackpot for Tuesday night's drawing is now at $636 million -- the second largest jackpot on record, but the odds of winning are slim.

Chances recently became even slimmer when more numbers were added to the mix.

There used to be 56 numbers. Now there are 75.

Still, every ticket sold brings at least a glimmer of hope of becoming a multi-millionaire.

"Well, there's always a possibility," said Ramiro Gomez, a lottery player.

"Somebody will win somewhere," said Jimmy Toubin, a lottery player.

Here are some scenarios to help put the odds of winning in perspective:

The odds of an amateur golfer hitting a hole in one on a par 3 course is 1 in 12,500.

The odds of being named a Saint by the Pope is 1 in 20 million.

The odds of being struck and killed by a meteor in the next year is 1 in 75 million

The odds of winning the Mega Millions jackpot are even greater; 1 in 259 million.

"The odds are just astronomical.  I have a better chance to become President than to win anything lottery related," said Diego Galicia, who said he prefers not to play.

Still, ticket sales are booming, despite the odds.

Lottery officials said if no one wins by Christmas, the Jackpot could reach a record billion dollars.
