Five places are left in the Round of 16 - and on Tuesday night we're going to find out who'll be taking them. We take you through the maths and what needs to happen on what is sure to be an exciting night!

Group A

• Frölunda Indians: Already qualified
• Vienna Capitals: Need to beat ZSC Lions by 4 goals to qualify. They can also do it if they win by three, but would need to score at least eight (i.e. 8-5, 9-6, 10-7 etc.). If it's 7-4 again, ZSC win the tie-break as higher seeds in the CHL ranking before the 2018/19 draw. However if Frölunda get 0 points in Aalborg, it's a three-way tie and Vienna would only need to win by a goal.
• ZSC Lions: Need to do no worse than lose to Vienna by two goals, or lose by three but not allow Vienna to score more then seven goals. If Aalborg win in regulation, the Lions will need at least a point.
• Aalborg Pirates: Eliminated, looking for first regulation win
   

Group B

• Red Bull Munich: Qualified, playing to secure top spot
• Malmö Redhawks: Qualified, playing to secure top spot
• TPS Turku: Eliminated
• Yunost Minsk: Eliminated, but have only ever lost once at home in the CHL
   

Group C

• Skellefteå AIK: Already qualified and top of the group
• HC Bolzano: Need to match IFK Helsinki's result as they hold the tie-break advantage.Therefore they will qualify if both teams lose
• IFK Helsinki: Must better HC Bolzano's result. If both get the same number of points, then IFK are eliminated due to worse Head-to-Head record
• GKS Tychy: Eliminated, playing to help Poland in the overall ranking and spoil Bolzano's party

• EV Zug: Qualified and secured top in the group
• Kometa Brno: Qualified
