Black\: Thomas and Mason
White\: Sarah and Eric

This is a special 4-person game of Hex suggested by Mason. Eric can only move in columns A-H. Sarah can only move in columns I-R. Thomas and Mason can only move in rows 1-9 and 10-18, respectively. The move order is counterclockwise\: Mason, Sarah, Thomas, Eric. For simplicity, there is no swap.
