Challenging Solitaire Games

Spider is a challenging solitaire card game with an 8% win rate in four-suit mode, played with two decks totaling 104 cards. Cards are dealt into ten tableau columns. The goal is to build complete descending sequences from King to Ace within a single suit. Completed sequences are removed until all cards are cleared.

Forty Thieves is a two-deck solitaire game with only a 10% win rate, dealing 40 cards face-up into ten tableau columns. Players build eight foundation piles from Ace to King by suit, moving one card at a time in same-suit descending sequences. It is among the most difficult classic solitaire variants.

Scorpion is a single-deck solitaire game with an 8% win rate across seven tableau columns. The goal is to build four complete King-to-Ace sequences by suit within the tableau itself, with no separate foundations. Any face-up card plus all cards on top may move together when the bottom card matches suit and rank.

Calculation is a solitaire game with a 50% win rate using a standard 52-card deck. Four foundation piles are each built by a different numerical interval: by 1s, 2s, 3s, and 4s, wrapping around from King back to Ace. Four waste piles serve as temporary storage while working through the stock.

Accordion is a single-row solitaire game with only a 1% win rate, played with one 52-card deck. Cards are dealt into a line, and players move any card onto the card to its left or three positions left when they share suit or rank. The goal is to compress all 52 cards into one pile.

Canfield is a single-deck solitaire game with only an 8% win rate, featuring a 13-card reserve pile, four tableau columns, and a stock pile. Foundation piles begin on a randomly chosen rank rather than Ace, and all four suits must build upward from that rank, wrapping from King back to Ace as needed.

La Belle Lucie is a classic patience game with a 10% win rate, played with one 52-card deck. All 52 cards deal into seventeen fans of three, plus one single-card fan. Only the outermost card of each fan is playable. Foundations build Ace to King by suit. Two redeals allowed. Empty fans cannot be refilled.

Russian Solitaire is a single-deck Yukon variant with only a 13% win rate. All 52 cards are dealt into seven tableau columns. Unlike Yukon, sequences must build down by suit only — not alternating colors. Any face-up card or group may move regardless of internal order. Foundations build up by suit from Ace to King.

Easthaven is a single-deck solitaire blending Spider and Klondike mechanics with a 25% win rate. Seven tableau columns of three cards each start with one face-up card. The stock deals one card to each column simultaneously. Sequences build down in alternating colors toward four foundations built up by suit from Ace to King.
