Spider Solitaire is a free iPhone game developed by GUI NING. It falls under the category of games and provides a classic card game experience on mobile devices.

The objective of Spider Solitaire is to remove all the cards from the table by assembling them in the tableau before removing them. In the beginning, 54 cards are dealt to the tableau in ten piles, with only the top cards face up. The tableau piles can be built down by rank, and in-suit sequences can be moved together.

One of the notable features of Spider Solitaire is the ability to deal 50 remaining cards to the tableau ten at a time, as long as none of the piles are empty. This allows for strategic planning and adds an element of challenge to the game.

Spider Solitaire provides a nostalgic and enjoyable card game experience on your iPhone. Whether you're a fan of classic solitaire games or looking for a new challenge, Spider Solitaire is a great choice.
