The Cypriot side bagged eleven three-pointers from 21 attempts and that was the difference in the game with both teams quite extraordinarily shooting and scoring the exact same numbers inside.
There was nothing to separate the teams during the early exchanges and at 23-23 it always looked like being a war of attrition with plenty on the line for both rivals.
The visitors moved into the lead with a 7-2 run and a nice jam by Taj Gray, but a 12-2 burst by the home team swung the game back in their favour and they led 45-39 going into the third.
Chalon struggled to establish themselves and keep pace in the penultimate period with the home team always delivering a killer blow from outside whenever the French side threatened to get over the hump.
In the end, Chalon didn't have enough and Apoel gleefully eased away down the stretch to put a new perspective on the standings in the Group.
Apoel had five players in double-figures to highlight how well they played with Milan Dozet top scoring with 18 points including four triples.
Taj Gray left disappointed with a loss but the consolation of being the top scorer in the game with 19 points.
Gerben Van Dorpe, APOEL player:
"This was a very important game for us. We knew what we had to do. We let them run for some time and they managed to close the gap. In the end we did what we had to do. The last game is an all or nothing for us."
Raphael Gaume, Elan Chalon assistant coach
"No basketball was played today because of the referees..."
Nicolas Lang, Elan Chalon player
"We lacked intensity and we could not get into a rhythm. It was very hard to concentrate."
