Binary Star

Also known as Black Holes

Goal

Move all cards to the foundations.

At a glance

Just like Black Hole, but with two decks, six cards per pile, and a second foundation, starting with a king of hearts. It does not matter how many cards end up in each foundation at the end of the game.

Base game rules: Black Hole

Goal

Move all cards to the single foundation.

How to play

The foundation (the Black Hole) builds up or down by rank ignoring color and suit, wrapping around from King to Ace and from Ace to King.

There is no building on the tableau piles, and spaces are not filled. Only the top card can be moved.

Playing tips

Plan carefully - one wrong move and you may never be able to untangle the mess.
