Lappeenranta rained down 14 three-pointers in advancing to the EuroCup Qualifying Round despite a 95-86 loss at Keravnos Nicosia.
Finnish international Petri Virtanen and Ivan Harris combined for 43 points and 10 three-pointers as the Finns made their 16-point home win stand up for a 173-164 aggregate victory in the second elimination round.
Adrian Terrell Henning and Reinar Hallik each added 12 points for Mika Turunen's team, who made 14-of-31 (45%) from downtown.
Keravnos' Aleksandar Radojevic had 26 points and nine rebounds, Bryant Smith collected 22 points and nine rebounds while Panagiotis Trisokkas added 15 and 11 in the victory, but the Cypriots only made 1-of-16 three-pointers.
Nicosia came out looking to score as they had the 16-point deficit to make up and grabbed a 12-6 lead early.
But Pasi Riihela and Harris knocked down back-to-back three-pointers - Lappeenranta's fourth and fifth treys of the night - to pull ahead 17-13.
Yet another long ball, this one by Virtanen, gave the Finns a 22-18 lead after one period.
Harris and Hallik hit from long range to retain a 32-27 cushion before Radojevic converted a three-point play and Aleksandar Damjanovic's lay-up gave the Cypriots a 38-36 lead.
Virtanen answered right back with another long ball and Turunen's Lappeenranta led 44-42 at the break.
Keravnos went ahead 47-45 on Patrick Lee's jumper but Henning dunked and Harris hit from downtown to regain the lead and Virtanen matched Harris from long range to push the gap to 55-51 and hit again for 58-55.
Smith's jumper gave the Cypriots a 68-62 lead but it was Hallik's turn as he hit from downtown and then converted a three-point play to close within 72-68 after three periods.
Keravnos started the fourth on an 8-2 run to open a 10-point lead 80-70 only to see Virtanen and Harris score lay-ups to bring it back down to six.
The Cypriots' bulge was back up to 10 at 86-76 before Virtanen hit from downtown again and his free throw cut the lead to 86-80 with less than two minutes remaining.
Panayiotis Yiannis pushed the lead back to nine points - 90-81 - but Keravnos could not hit their three-pointers as they tried to get to that crucial 16-point mark.
Mika Turunen, head coach Lappeenranta:
"It was a tough game. We knew that we would not have an easy night, as Keravnos always plays very well at home. Number 12 and number 15 of Keravnos nearly killed us at the start but we played smart. I am very proud for my team as we had 3 players fouled out and our big man, who was injured last game, did not have time to prepare. This win is very important for the Finnish and Nordic basketball, as our team is the only team which qualified."
Petri Virtanen, Lappeenranta guard:
"We played very good especially in the first half. Then we became too confident and made several turnovers. We knew that Keravnos is a tough team. Our three-point shooting was really good tonight and won us the game. Keravnos won 19 offensive rebounds and this shows their strength and aggression."
Panayiotis Yiannaras, Keravnos assistant coach:
"Congratulations to Lappeenranta for the win and qualification. Our team tried very hard but Lappeenranta hit some very big three-pointers, in the first half especially. It seems that we failed to qualify after losing the first game by 16 points. We also had a very bad % from outside the three-point line, especially at crucial parts of the game. Congratulations to Lappeenranta and good luck in the competition.
Panayiotis Trisokkas, Keravnos forward:
"Firstly, congratulations to Lappeenranta and good luck in the competition. We started this season with a lot of dreams following last year’s great run in the FIBA Euro Cup Challenge, when we reached the Final. We have been knocked out because we lost the first game by 16 points and couldn’t cover the difference tonight. We did not start well tonight, as our plan was to win by 4 points each quarter and cover the difference. We managed, twice to take a 10 point lead, with lots of time to spare, but we missed the easy three-point shots at critical parts of the game. My team needs to pick up the pieces, as we have two very important games in the league. We all have to assume our responsibilities."
