“If you want to get in on the action, playing the Rate the Game beta contest is easy. First, visit your account management page, download and install the Arcade (1.5.0) Beta product you see in the game accounts section, then hop into the Arcade. To enter the contest, simply play, rate, and review an Arcade game. The first time you rate and review a new game each day the contest is running gives you another chance to win, so it pays to visit every day until the contest ends. At the end of the contest period we’ll randomly choose 500 eligible contestants to win StarCraft II: Heart of the Swarm beta keys!” -Blizzard
Go here to opt into the Arcade (1.5.0) Beta.
Remember! You can come back each day from now until the 29th to rate a game and get another chance to win a Heart of the Swarm beta key! There are only going to be 500 winners, so every day you play will really help!
Good luck!
