Hearthstone News: Developers reveal how matchmaking works

Looks like we're going to need a new conspiracy theory.

If you've ever found yourself horribly frustrated in Hearthstone, getting beaten over and over by the same deck, only to switch to a counter and then never see your nemesis again....well, you're certainly not alone.

While it's sometimes tempting to believe that there's some hidden mechanism in the matchmaking system, analysing your match history and tweaking future match-ups accordingly, developer Max McCall piped up on the forums last night to finally put those fears to bed.

Here's a summary of what was confirmed:

  • Your skill rating - and only your skill rating - affects your next likely opponent.
  • This rating - your MMR - is adjusted at the end of each game, based on whether you won or lost, your opponent's rating, and your rating history.
  • At Legend and in Casual, players are paired up based on similar ratings. In Ranked play but below Legend, it's based on your star rank.
  • The matchmaking system is never, ever fed information about the deck type you're piloting, or decks that you've faced. Only the MMR matters.
  • When you queue up, the matchmaker assesses your MMR and looks for an opponent with the same MMR. If it finds one, the match begins. If not, it waits a few seconds and tries again. After that, it will start looking for a player with almost the same MMR. The pool keeps gradually widening until you're in a match.
  • Typically, a match will be found so quickly that the pool never has to be widened at all.

Looks like we have official word, then, that the only person we can blame when we go tumbling down the rankings is ourselves. Which is a bit of a bummer when you think about it really...
