The start of May means one thing; the World Series of Poker is quickly approaching. While the series technically begins with the Casino Employees event on May 31st, the two biggest events on the schedule, using different definitions of big, are exactly one month away.

The Colossus, big in terms of field size, and the $111,111 buy-in High Roller for ONE DROP, big in terms of a mind-numbing price point, open the series for recreational players, professionals and High Rollers alike, with both events getting cards in the air on June 2nd. So, what do you need to know about each event before looking at the rest of the 2017 World Series of Poker schedule?

Back for a third straight year, The Colossus doesn’t only offer players a chance at a WSOP bracelet for a small $565 buy-in, but also a chance at a massive payout. This year’s event will boast an $8 million guaranteed prize pool and The Colossus will also see all six starting flights play into the money, meaning players could technically cash multiple times. Cashing more than once would be nice but every one of the over 20,000 players that take their shot in The Colossus will have their sights set on the top prize, where $1 million is guaranteed for the eventual winner.

Opposite to The Colossus, the High Roller for ONE DROP boasts the WSOP’s biggest buy-in and while the last few fields have failed to break 200 entrants, there is always a massive prize pool up for grabs. Last year, Fedor Holz took home the lion’s share of a $19 million prize pool, claiming nearly $5 million and his first WSOP bracelet, and this year’s early-June event should draw similar numbers, piggy-backing off the big buy-in Super High Roller Bowl.

While most will start their summer with the former, instead of the massive buy-in latter, players will be competing for massive prize pools no matter which even they choose come next month. That trend will likely continue throughout the summer, as last year’s WSOP set attendance records for the second straight year and awarded over $221 million in total prize money.
