The lottery buying phase is nearly done. Starting at the following times you can go check to see if yours is the winning ticket:

EDT: 11 AM.
CDT: 10 AM.
MDT: 9 AM.
PDT: 8 AM.

(This coincides with the daily roulette reset.)

You will have 4 days from then to claim your plot, if you don't it will be recycled into the next lotto period and you will only be able to get back 50% of the ticket you purchased but did not act on.

For losing tickets, head for the placard you bought from to get your gil back. Good luck on the next lotto round in 4 days.
