Master Spider is a Spider Solitaire card game. It requires the player to prove their mastery of the rules and requirements of this specific form of solitaire play.
On a gradient-green tabletop, the player rearranges one- or two-suit face-up and face-down cards in 10 columns and pulls cards from a 10-card-draw pile to create eight new descending order (K, Q, J...) columns. These columns are the legs of the spider. Whenever the player finishes a build, the game automatically sends it as a pile to one of the empty spaces above the columns.
The player can choose to play an easy-to-moderate difficulty mode with one suit by using the 1 Suit button or a hard-to-expert mode with two suits by using the 2 Suit button. If either mode causes them too many problems, they can use the Hint button to reveal a reordering possibility, the Undo button to reverse their last build decision, or the New Game button to start over entirely. They can transfer any part of a build to an entirely empty column space. They can also use the draw pile to add 10 cards at a time to the columns to fill any descending-order gaps. That said, they should wait to use the draw pile until they've built at least half the legs because these cards block current builds, which makes creating legs more difficult.
Master Spider also permits the player to select special card design options. When they use the Skins Button, they can pick default or classic, vintage, star, Slavic, king, skeleton, pirate, minimalist, gemstone, Christmas and cartoon design options.
