The Board of Governors approved a modification of the Lottery system in November of 1993 that, effective with the 1994 NBA Draft Lottery, increased the chances of the teams with the worst records in the league winning one of the top three picks in the draft while decreasing the lottery chances of the teams with the best records. The new system increased the chances of the team with the worst record drawing the first pick in the draft from 16.7 percent to 25 percent, while decreasing the chances of the team with the best record among lottery teams from 1.5 percent to 0.5 percent.
Under the system, 14 ping-pong balls numbered 1 through 14 are placed in a drum. There are 1,001 possible combinations when four balls are drawn out of 14, without regard to their order of selection. Prior to the Lottery, 1,000 combinations are assigned to the Lottery teams based on their order of finish during the regular season. Four balls are drawn to the top to determine a four-digit combination. The team that has been assigned that combination will receive the number one pick. The four balls are placed back in the drum and the process is repeated to determine the number two and three picks. (Note: If the one unassigned combination is drawn, the balls are drawn to the top again.)
