How to play
Draw one card, then place it on a foundation that needs its rank or into a holding pile. Only holding-pile top cards can build to foundations. Complete all four thirteen-card sequences, each ending at king.
Modes and local progress
Calculation Solitaire starts four foundations at ace, two, three and four. Their sequences advance by steps of one, two, three and four, wrapping after king; suits do not matter. Draw the other 48 cards once, keeping future foundation cards accessible in four holding piles. Inspect piles reveals only dealt cards, and Build reserve top lets you play an available top card even while holding a drawn card.
