Speed Fiend Free is the free version of the popular card game Speed Fiend. It is a fast-paced and addictive game that is perfectly suited for the iPhone's touch screen. Unlike most card games, Speed Fiend does not have turns. Players race against a computer opponent to be the first to play all their cards. The game is easy to learn and plays like an arcade game, adding the challenge of developing quick reflexes.

The rules of Speed Fiend are simple. Players play cards by dragging them onto the discard piles, with the requirement that the card played must be one higher or lower than the card on the pile. Players can tap their reserve deck to draw more cards. The goal is to play all your cards before your opponent.

In the free version of Speed Fiend, players have access to the first four out of nine levels of difficulty available in the full version. They also have a choice of four decks and can customize the position of the draw deck for handedness or preference. The game features faithful simulation of cards in the deck throughout the game, including discard piles.

Speed Fiend Free offers a taste of the addictive gameplay of Speed Fiend. If players enjoy the free version, they can upgrade to the full version, which offers five more difficult levels, two-player mode, leaderboards on GameCenter, and no ads.
