Meet Spiderette
Keep these points in mind. The smaller deck does not remove the need to manage suit changes. The tableau contains seven columns rather than ten. Spiderette on qifanvalve.com uses one 52-card deck with all four suits. Four complete same-suit King-to-Ace runs win the game.
The opening staircase
A few details help explain this feature. The seventh opening column contains seven cards. The first opening column contains one card and each following column contains one more. The opening tableau contains 28 cards altogether. Only the bottom card of each initial column is face up.
Twenty-four stock cards
Here are the details for this mode. A full stock deal adds one card to each of the seven columns. The final stock deal contains three cards for the first three columns. The stock is used in deals of seven, seven, seven and three cards. Spiderette begins with 24 cards in the stock.
Build down by rank
Here are the details for this mode. A single exposed card can land on another exposed card exactly one rank higher. Any exposed card may enter an empty column. A King can enter only an empty column because no rank is higher. A destination card may belong to a different suit.
Move a sequence
Keep these points in mind. A mixed-suit descending sequence cannot move as one group. A movable group must be face up and descend in one suit. The selected group's leading card determines which destination rank is legal. Selecting a shorter matching segment can reveal an available group move.
Expose another card
Keep these points in mind. Undo restores a hidden card's earlier state when the revealing action is reversed. No separate click is needed to reveal a newly uncovered card. An exposed hidden card can create another possible destination. Moving all exposed cards off a hidden card turns that hidden card face up.
Prepare to use the stock
This Spiderette version requires every column to contain a card before a stock deal. Any valid movable group can fill an empty column. An empty column prevents dealing even when only the final three stock cards remain. A stock deal may interrupt a sequence you were assembling.
Collect all four suits
The following details apply here. One run is needed for spades, hearts, clubs and diamonds. A complete face-up run is removed automatically from the bottom of a column. Four collected runs account for every card in the deck. A qualifying run contains thirteen cards of one suit from King down to Ace.
Useful practice controls
Here are the details for this mode. Replay starts the same Spiderette shuffle again. Undo reverses a successful move or stock deal while recent history is available. Hint suggests a legal move without checking every possible future continuation. A random Spiderette shuffle is not advertised as guaranteed winnable.

A few details help explain this feature. My Statistics records Spiderette separately from standard Spider. Spiderette has its own saved position in this browser when saving is enabled.
