To guarantee entry, you need to be in the top 8 (see below).\n\nClock settings and Rules are the same as for the ladder.\n\nThis tournament effectively uses the Site 9x9 ladder for its preliminaries.\n\n# Invitational Process:\nOn the 8th of January 2019, I will take a snapshot of the ladder and send invitations to the top 8 players. Each day thereafter, I will send additional invitations equal to the number of vacancies until the tournament is full, working down the ladder no further than position 30.\n\nIf you receive an invitation, decide quickly. The top eight will get ~24hrs to decide but thereafter the additional invitees could miss out as those above make late acceptances.\n\nIf for whatever reason, you need your invitation to be resent, just ask with a pm.\n\nInvitations Update:\nThe following is the order of invitation taken from the ladder at 9am 8-Jan-'19 GMT\n1. Thousand Rain - Invited 8-Jan-'19\n2. Vortex - Invited 8-Jan-'19\n3. jurkos - Invited 8-Jan-'19\n4. Sadaharu - Invited 8-Jan-'19\n5. lovecall - Invited 8-Jan-'19\n6.
