One deck, seven Klondike piles, and Spider's same-suit runs: build down regardless of suit, but only matching-suit sequences move together in this hard, one-pack game.

Spiderette Solitaire is Spider Solitaire squeezed into a single deck. Instead of Spider's ten wide columns, the cards land on Klondike's familiar seven-pile staircase — one to seven cards per pile, with only the top card showing — while the remaining twenty-four cards wait in the stock. It has long been the classic answer for players who want Spider's sequence-building with just one pack of cards.
The rules will feel instantly familiar to Spider fans: build down regardless of suit, but only same-suit runs move together, and each tap of the stock throws a fresh card onto every column. Because a deal covers whatever you have built so far, timing your deals is half the battle.
It's a hard game, since sorting all four suits out of a single deck leaves little room for error. It uses one deck, and winning takes a mix of skill and luck.
Spider Solitaire is the game Spiderette shrinks down to one deck, and Spidike Solitaire takes the same triangular board but sends cards to the foundation one at a time instead of in full sequences.
When you want the simpler, no-suit-sorting version, original Solitaire is right there.

4 foundation piles: Completed sequences of thirteen cards, from King down to Ace in a single suit, are moved here. Fill all four to win.
7 tableau piles: Build down in any suit. Cards in sequence down in the same suit can be moved as a group. Any card or valid group can fill a space. At the start of the game, the piles are dealt one to seven cards; only the top card is shown.
Stock: Click to deal one card onto every tableau pile. No pile may be empty when you deal, and there are no redeals.
There are four foundation piles.
Single cards are never allowed to be moved to the foundation. Only once you have built a complete sequence on the tableau — thirteen cards of the same suit running from King down to Ace — can it be transferred to a foundation pile.
The game is won when every card has been sorted into descending order; in practice, that means completing all four suits.
There are seven tableau piles, dealt one to seven cards. The top card of each pile is dealt face-up, while the remaining cards are dealt face-down and turn over as they become uncovered.
A card can be added to a tableau pile only if it's one rank lower than the pile's current top card, regardless of suit, so any 5 fits on a 6. Groups of cards, however, only move together when they are in descending order of the same suit — so mixing suits is legal but costs you mobility.
Cards on the tableau that are not covered by another card can be played onto any other tableau pile.
Any card or movable group can fill an empty slot in the tableau.
The stock is made up of the twenty-four leftover cards.
When you click on the stock, one card is dealt face-up onto each tableau pile. You may not deal while any tableau pile is empty. The first three deals place seven cards each; the fourth and final deal places just three, and there are no redeals.
