Elite League champions Cardiff were drawn in Group E alongside HC Davos (Switzerland), Bili Tygri Liberec (Czech Republic) and Vaxjo Lakers (Sweden).
The Group Stage starts on 24th August and finishes on 11th October. The 32 teams are divided into eight groups of four and each team plays six games – one home and one away against the other three teams in its group.
The first and second placed teams in each group then advance to the Play-off Stage.
With 16 teams in the play-offs, four rounds are required to determine the European club champions. The first three rounds are all two-game, home-and-away, aggregate-scoring series, similar to the previous seasons.
The play-offs start on 31st October and finish with the ultimate one-game final on 6th February 2018.
