The teams continued to trade the lead with neither able to find any separation.
Aliaksei Trastsinetski's free throw put Minsk up 81-79 with 17 seconds left in overtime, but Chris Young went to the line with one second left and hit both to send it to a second extra period.
Minsk hit first, with Pavel Ulyanko's free throws giving them a four-point lead but Okapi wiped it out with six straight.
They won it on defence at the end, getting away with missed free throws down the stretch as they held Minsk scoreless for the final two minutes.
Raivio led Okapi with 25 points while Larry Anderson had 16 and Young 13.
