November 8–24 | The Day and Evening Series
This year’s OSS schedule is split into two parts: the Day Series, featuring tournaments scheduled for earlier hours (ideal for European players), and the Evening Series, with tournaments starting at U.S.-friendly times (marked with a flag in the lobby).
The four main events come with $4,250,000 in combined guarantees. All four tournaments have multiple starting flights, so you can play as many as you like, with your stacks combined for Day 2.
