The Humble Bundle is shifting from its bi-weekly pay-what-you-want packages of independent game titles to a more common 24/7 digital storefront.

The Humble Bundle is a website that offers game titles at reasonable prices and shares its 10 percent sales with charity organizations such as American Red Cross, Child's Play, Electronic Frontier Foundation, World Land Trust and Charity Water. The online game store that used to offer bi-weekly purchase option of independent game titles, is extending to a 24/7 digital storefront.

The new Humble Store will work round-the-clock in offering games for multiple platforms including Steam and DRM-free versions at best prices. The new online store will continue to offer its popular pay-what-you-want Humble Bundle collections and Weekly Sales. Latest deals with best prices will be updated on the Humble Store to keep its customers engaged.

"The Humble Store is a permanent addition to our Humble site that will allow our customers to buy great games at great prices 24/7 and support charity with every purchase," the company said in a blog announcement.

To mark today's grand opening, the Humble Store is offering DRM-free downloads of select game titles for 50 to 75 percent off on their retail tags. These games include Don't Starve, Natural Selection II, Euro Truck Simulator 2, The Swapper, Prison Architect, Rogue Legacy, Chivalry: Medieval Warfare, Orcs Must Die! 2 and Gunpoint. The offer lasts only till 2 p.m. Eastern Time on Tuesday, before new titles take the discount shelves on the online store.

According to the company's data, more than $50 million earnings have been reported as of August. The company has contributed $20 million to partner charity foundations. The extension of the sales system marks a huge step in the company's path to success.
