Today is a big day at the 2015 World Series of Poker. At 4 p.m. local time in Las Vegas, the most noble and prestigious event the poker world has to offer will kick off — the $50,000 Poker Players' Championship.

This year will be the 10th installment of the event that high-stakes poker players from across the globe deem as the most important event of the year, and the one they all want to win more than anything. With an average field size of 124 entries and an average first-place prize of just under $1.7 million over the years, the field will be small, but immensely skilled, and there will be plenty of money to be won.

This year, two new games have been added to the mix, but this isn't the first time that this tournament has seen a format change. The event originally started as a $50,000 H.O.R.S.E. tournament in 2006. It was played in this format up until 2010, when it was then changed to an eight-game format with the addition of no-limit hold'em, pot-limit Omaha, and 2-7 triple draw. This year, two more games have been added, with badugi and no-limit 2-7 single draw now being in play.
