Spider's tableau meets Klondike's one-card foundations in this one-deck hybrid, where clearing columns for Kings takes a mix of skill and a little luck.

Thomas Warfield blended Spider and Klondike into a single one-deck game, and Spidike Solitaire is the result. The triangular seven-column tableau is dealt exactly like Spiderette, so the board looks familiar the moment the cards fly out. The twist lives in how you win: instead of clearing full King-to-Ace sequences inside the columns, you carry cards up to four ordinary foundations one at a time, the way Klondike does.
That single change reshapes the whole game. You still build the tableau downward regardless of suit and slide same-suit runs from column to column, but the foundations quietly reward you for freeing low cards early. Aces and twos that would sit dead in classic Spider suddenly have somewhere to go, and the automatic collection keeps the board tidy while you plan.
It is a single-deck game, dealt through the stock in one pass of 7-7-7-3 cards with no redeals, so tempo matters. Empty columns fill only with Kings, which makes clearing a pile a real strategic decision rather than a free reset. Your odds of victory come down to a balance of skill and a little luck.
Spiderette Solitaire deals the same triangular board but scores whole sequences instead of single cards, and Spider Solitaire is the game Spidike borrows its tableau from.
Or step back to Klondike's roots with the original Solitaire.

4 foundation piles: Build up by suit from Ace to King. Cards are collected here one at a time and are moved automatically when a legal play is available.
7 tableau piles: The columns are dealt in a triangle, from one card up to seven, with every card face down except the top of each pile. Build down regardless of suit, and move runs only when they are all of the same suit.
Stock: Click to deal a full row of cards, one to each tableau pile, across a single pass through the deck. There are no redeals.
There are four foundation piles, all empty at the start.
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 the 7 of clubs is the 8 of clubs. Each pile runs from Ace up to King and holds thirteen cards.
Whenever a card can move to a foundation, the game collects it automatically. Cards cannot be taken back from the foundation once they have been placed.
There are seven tableau piles, dealt from one card in the first pile to seven in the last. Only the top card of each pile starts face-up; the rest are revealed as you uncover them.
A card can be added to a tableau pile only if it's one rank lower than the pile's current top card, of any suit, so the only card that fits on a 9 is any 8. A group of cards may be moved together only when it forms a descending run of a single suit.
Cards on the tableau that are not covered by another card can be played onto the foundation or onto another tableau pile.
Empty tableau columns may be filled only with a King, or with a same-suit run headed by a King.
The remaining cards after the deal make up the stock, and there is no separate waste pile.
When you click on the stock, one card is dealt to every tableau pile at once, even a pile that happens to be empty. You only get one pass through the stock, so spend each deal carefully.
