Play Diablo 3 for Free with Starter Edition
Diablo 3 Starter Edition serves as a free trial for the online rpg. You can reach level 13 without having to purchase a Diablo 3 game copy. Free players will have access to Global Play, and will be able to use the matchmaking feature for multiplayer adventures, but only with other Starter Edition edition players. Also, absolutely no Auction House access either for real money or Gold.
Blizzard said these restrictions can be removed if and when free players choose to purchase the game and upgrade to a normal account. “Any progress and achievements you earn while playing the Starter Edition will automatically carry over if you decide to upgrade to the full version of Diablo 3, and the Starter Edition restrictions will be removed.”
Diablo 3 Starter Edition can only be downloaded when you have a Battle.net account. If you do not have one, click here to make your own. If you have an existing Battle.net account (probably from playing the World of Warcraft MMO or other Blizzard titles) start downloading the free client by logging on to Battle.net. Detailed instructions can be found in the Diablo 3 Starter Edition FAQ.
