Welcome to Test Season 2 of Hearthstone’s Ranked Play mode! At the beginning of each Ranked Play season, all players will have their ranks reset to Rank 25. Test Season 2 will last until the end of the month, which should allow you ample time to work your way up the ladder to become a Hearthstone legend! Your continued testing efforts help us make all of our games modes a better experience for all Hearthstone players, and your feedback is greatly appreciated.

Please note that during our Test Seasons, Ranked Play rewards will not be available.

Please continue to submit your feedback on our Ranked Play mode on our forums here. If you discover any bugs during your duels, our Bug Report forums can be found here - let us know about them!

Tired of being an Angry Chicken? Battle against other players of similar rank to ascend the Ranked Play ladder and become a Hearthstone legend!

Have a safe and happy New Year from all of us on the Hearthstone team!
