Sacrifice the Minions not working?

I missed out on the doomed minion icon last year because I played the minion game on the NA website instead of the OCE one so I was stoked when I found out they were reintroducing the game this year. However it's not working for me? Like I'll click the little button but nothing happens. Sorry if this is a dumb post but I am absolutely desperate for that icon (PS I've tried the game on my chromebook and desktop, doesn't work on either of them) am I just making a stupid mistake
