Sudden Death

Sudden Death strips two decks down to their high cards — Nines through Aces, forty-eight cards — and runs its foundations up from Nine to Ace and then all the way back down again.

The name oversells it. With only six ranks in play across ten piles there is nearly always something legal to do, and the reference rates it Easy. The one thing to get right is the direction each pile commits to, since a pile cannot reverse once it has started — decide what each is for before you use it, and the rest follows.

Two decks stripped down to their high cards — every 2 through 8 removed, leaving 48 cards of Nine through Ace. Ten piles start with one card each. The foundations run up from Nine through King to Ace, then back down through King to Nine and finish on an Ace. Tableau piles build up or down in suit, but once a pile has committed to a direction it cannot reverse. There is no redeal.

The no-direction-change rule is the only real decision and it comes early: committing a pile upward means everything you later add there must continue upward. With only six ranks in play there are eight of each, so most cards have somewhere to go — decide what each pile is for and stick to it. Because the foundations run up and then back down, nearly every rank is wanted twice at separated moments, so a card that looks dead now often has a later window. Rated Easy, and the stripped deck is why: with six ranks and ten piles there is nearly always a legal move.
