Twelve cards open Busy Aces, one in each tableau column. Most of the two decks remain in the 92-card stock, which you may pass through only once.
A suited run must be handled card by card
Build columns down by suit. Only individual exposed cards move, and any card can occupy an empty column. Eight foundations start with aces and build upward by suit through king. Only the exposed waste card is playable; there is no stock redeal.
Do not consume every receiving space
A new waste card can become a helpful receiver, but parking it in the last empty column may stop you from separating an existing run. Inspect which low cards are blocked before taking the draw. With duplicate ranks, choose the copy that exposes another card or preserves a useful suited receiver.
