The biggest buy-in poker tournament – the Big One for One Drop – in history is back for 2016, but there are a few important changes that will be sure to catch a few people by surprise.

“The Big One for One Drop is back. This time at the iconic casino in Monte Carlo in a new reinvented format for recreational players only,” said Guy Laliberte, theCirque du Soleil founder who helped create the One Drop charity.

That’s right – recreational players only. Poker superstars like Daniel Negreanu, Antonio Esfandiari and Erik Seidel won’t be able to play under the format change. Laliberte hopes this will have a net-positive impact on the charitable initiatives of One Drop.

“From the beginning, we knew that The Big One for One Drop was a unique event,” said Laliberté. “This year, by shifting the focus to recreational players, we’re looking to bring fun and innovation to charitable giving. We believe the events in Monaco will attract high net-worth individuals from across the globe to enjoy the game, the networking opportunities and the incredible VIP experiences only available in one of the world’s most iconic settings.”

The €1 million buy-in Big One for One Drop runs October 14 – 16 at the Casino de Monte-Carlo in Monaco. Players will be able to re-enter until the end of Day 1 and €111,111 of each buy-in goes directly to the One Drop charity. One Drop works to provide better access to clean water in third world countries.

The other important change for 2016 is the buy-in. The $1 million buy-in has been replaced by a €1 million buy-in. At current exchange rates that equals $1.1 million buy-in making it the largest buy-in tournament in history.

“The Monte Carlo One Drop Extravaganza featuring the Big One for One Drop Invitational surrounded by a full slate of tournaments and cash games every day,” said Laliberte. “Players from around the world will come to this exclusive destination October 13 – 17.”

The festival schedule includes a day full of Step qualifiers with buy-ins of €10,000, €50,000 and €250,000. There are also seven other tournaments with buy-ins ranging from €10,000 to €100,000. A portion of each buy-in goes directly to the One Drop charity.

There is also a €1,000,000 buy-in cash game running on October 17.

The Big One for One Drop, which attracted a mix of top-flight professional players and wealthy businessmen looking to test their poker game in a high-stakes tournament, debuted at the 2012 World Series of Poker and was won by Esfandiari. It ran again two years later when Dan Colman beat Negreanu heads up to win the $15 million first place prize.
