Barys and Admiral were the days top scorers, with both teams netting six in comfortable home wins.
Admiral beat Dinamo Minsk 6-3 after three goals in the final session snapped a 3-3 tie. Denis Kuzmin got the go-ahead goal just 13 seconds after the restart before Felix Schutz got his second of the evening and Niclas Bergfors completed the scoring.
A few hours later Barys powered to a 6-1 success over Slovan. Roman Savchenko got the only goal of the first period, but the middle session proved decisive. Konstantin Pushkaryov and Kevin Dallman scored within 60 seconds of one another and even though Vaclav Nedorost pulled one back shortly afterwards, Konstantin Rudenko stretched the lead to 4-1 before the second intermission.
Third-period goals from Roman Starchenko and Konstantin Romanov completed the rout; Barys scored six times from just 26 shots on goal.
Medvescak had led twice earlier in the game but Andrew Hutchinson and Matt Anderson saw their second-period goals cancelled out by Sergei Dorofeyev and Kirill Kaprizov.
Sibir’s Mikko Koskinen also enjoyed a shut-out as his team beat Dinamo Riga 3-0. Dmitry Monya and Jonas Enlund seized the initiative for Sibir shortly after midway, and Oleg Gubin completed the scoring late on.
