Card Games > Calculation
Calculation offers more scope for skill than many similar games; a skilled player can win Calculation at least nine times out of ten.
At the start of play, one ace, deuce, three, and four of any suit are removed from a standard deck of cards and laid out as the foundations. The ace foundation is to be built up in sequence until the king is reached, disregarding suit. The other foundations are similarly built up, but by twos, threes, and fours, respectively, until they each reach a king.
