The brief cites previous XL Autumn Series winners to show what the Main Events have paid out in similar fields. In last year's festival, "amormori" of Romania won the $250 Mystery Main Event for $55,782 after outlasting 2,319 entrants. The $25 Mystery Mini Main was won by "brocanuts," who collected $6,077 after a 4,413-player field.

# What to expect for players Players targeting value should note that mystery bounties are the majority of events and that the two headline Mystery Main Events require substantial entries to avoid overlays. The larger $109 Opening Event's increased guarantee to $100,000 could make that flight attractive to grinders. Satellites and multiple Day 1 flights are available for both Main Events.

# Practical timeline details The numbered events begin on Sept. 20 and conclude on Sept. 29. Day 2 for the Mini Main and Main Event is scheduled for Sept. 28 at 9:30 p.m. BST. Many events are scheduled in the evening BST timeslot, with several daytime flights across the series.

# Reading the schedule The published table provides dates, start times, buy-ins, and guarantees for each of the 41 numbered events. Players should consult the schedule for the precise start time and format of any event they plan to enter.
