Steam is an internet-based digital distribution, digital rights management, multiplayer, and social networking platform developed by Valve Corporation. Steam provides the user with installation and automatic updating of games on multiple computers, and community features such as friends lists and groups, cloud saving, and in-game voice and chat functionality.

The holiday sale from Steam, Valve's online game retailer, will offer three options for gamers: daily deals, flash sales, and community's choice. The sale starts today and runs for the next 15 days — until 10 a.m. on Jan. 2.

Daily deals will provide discounts on specific games for 24 hours. The Steam Holiday Sale also features 6 new "flash" deals every 12 hours.

Are there any titles you want to buy, but don't see on sale? That's where the "Community's Choice" section comes in. Every 24 hours, Steam will offer up three games and ask players which one they want to get the discount.
