The NHL Entry Draft is held each June, allowing teams to select players who have turned 18 years old by September 15 in the year the draft is held. The draft order is determined by the previous season's order of finish, with non-playoff teams drafting first, followed by the teams that made the playoffs, with the specific order determined by the number of points earned by each team. Since 2016, the NHL holds a weighted lottery for the 15 non-playoff teams, allowing the winners to move up to the top three selections. From 1995–2012 the winner of the draft lottery was allowed to move up a maximum of four positions in the entry draft. The team with the fewest points has the best chance of winning the lottery, with each successive team given a lower chance of moving up in the draft. The Oilers have won the lottery three times, in 2010, 2012 and 2015. Between 1986 and 1994, the NHL also held a Supplemental Draft for players in American colleges.
