Black Hole Solitaire

Black Hole Solitaire is a space-themed card game based on the familiar ideas of Tri Peaks and golf solitaire. Your central task is to send every card into the black hole by selecting cards that count upward or downward in value.

The choice between easy and hard play changes how much planning the layout demands. Easy mode allows cards to move into empty spaces, while hard mode removes that convenience and asks you to manage the available sequence more carefully.

Select cards in an order that counts up or down in value from the current card.

Continue moving cards until every card has been sent to the black hole.

In easy mode, use empty spaces when they are available to support your sequence.

Choose hard mode when you want to plan around the stricter card arrangement.
