EA has launched its Origin Access Premier program, and alongside it the company is quietly ending its practice of regularly giving away free PC games through the Origin service. The "On the House" program has been tempting users into the Origin platform with free giveaways since 2014, but no more.

"Origin On the House will be retired and games will no longer be offered through the program," an EA spokesperson told Rock Paper Shotgun. "This change won't affect any games you downloaded from the service prior to that date--those are yours to keep forever."
