First, 18 piles (or fans) of three cards are dealt. During this deal any ace encountered regardless of where it would end up in the pile will be moved to a foundation and be replaced with another card. As they become available, the other aces are placed on the foundations, which are all built up by suit.
The top cards of the piles are available to be built on the foundations or on each other's piles on the tableau. When building on the tableau, the cards are built either up or down by suit. Aces cannot be placed over kings, however, and vice versa.
When a gap occurs, it is immediately filled by three new cards from the stock. This is the only way cards from the stock are introduced from the game and the only way spaces are refilled. As in the original deal, any ace that comes up is immediately placed on the foundations.
Doom is a series of first-person shootervideo games developed by id Software. The series focuses on the exploits of an unnamed space marine operating under the auspices of Union Aerospace Corporation (UAC), who fights hordes of demons and the undead in order to survive.
Doom is considered to be one of the pioneering first-person shooter games, introducing to IBM-compatible computers features such as 3D graphics, third dimension spatiality, networked multiplayer gameplay, and support for player-created modifications with the Doom WAD format. Since the release of Doom in 1993, the series has spawned numerous sequels, expansion packs, and a film.
Since its debut, over 10 million copies of games in the Doom series have been sold.
