Titan takes Giant's eight-pile layout and deals three cards per pile instead of one, so you open with far more to juggle. Same tableau, same single pass through the stock.

Titan Solitaire is the two-deck, three-card-per-pile cousin of Giant Solitaire: where Giant starts you with a single card on each of its eight piles, Titan deals three, giving you more to work with right from the opening deal. Both games share the same eight foundations, the same alternating-color tableau, and the same single pass through the stock, so those extra starting cards are really the whole difference between them.
If you enjoy Titan, you should try Solitaire, a classic solitaire card game.
If you run into anything odd or have an idea that would make the game better, please contact me.

There are eight foundation piles.
Any ace in the foundation may be transferred to any vacant pile.
A card can be added to a foundation pile only if it's one rank higher and the same suit as the pile's current top card, so the only card that fits on a 7 of hearts is an 8 of hearts. There can be no more than 13 cards in a pile.
The top card of each foundation can be moved back into play if another pile will accept it.
Eight tableau piles of three cards each, dealt face-up.
A card can be added to a tableau pile only if it's one rank lower and the opposite color of the pile's current top card, so the only cards that fit on an 8 of hearts are the 7 of spades and 7 of clubs.
Cards on the tableau that are not covered by another card are free to be played onto the foundation or any other tableau pile.
Any card can fill an empty slot in the tableau.
If the cards are alternately red and black, groups of cards in succession from high to low can be shifted from one tableau column to another.
The stock is made up of leftover cards.
When you click on the stock, a card is dealt to the top of each tableau pile. There's only one pass through the stock, so make it count.
