Spiderette is Spider shrunk to one deck and dealt on the Klondike staircase. Baby Spiderette keeps that board and borrows one rule from Black Widow: any descending run moves as a unit, whatever suits it mixes. Seven columns of one to seven cards are dealt with only the tip of each turned, the remaining twenty-four wait in a stock that deals a card to every column at once, and the goal is the same as Spider's — build each suit from king down to ace within the columns and lift it off. With mixed runs free to travel, the game is about keeping same-suit sequences together on purpose, because only those ever leave the board.
Free runs are for digging, not for finishing. A mixed run moves whole, which makes uncovering hidden cards cheap. But only a single-suit run ever leaves the board, so every mixed run you build is one you must later sort. Dig with mixed runs early; build clean ones as the suits appear.
Fill every column before you deal. The stock refuses to deal while a column is empty, and a deal covers every column with a new card. Make the most of an empty column — relocate a run through it — then fill it and deal only when the board is exhausted.
Twenty-four cards is three and a half deals. The stock is small. Plan for the last deal of three cards, which lands on the first three columns only, and keep those columns tidy.
One deck means one of each. Every card has one higher card of its suit. When that card is buried, a same-suit run cannot grow past it; look for the copy before you commit the run.
Spider's identity is the collected suit run and the row-dealing stock. Spiderette scales the game to one deck on Klondike's staircase; Black Widow keeps two decks and lets mixed runs travel. Baby Spiderette is the meeting of the two: Spiderette's board with Black Widow's run rule, the most forgiving one-deck member of the family and a good first Spider.
