Draco Calculation plays Calculation (Broken Intervals) solitaire card game. If you’re new to Calculation follow the in-game instructions, or tap the hint icon (?) if you need a suggestion. The game involves some strategy although easy to learn.

The game begins with an ace, two, three, and four dealt to their respective foundation stacks. The Ace foundation stack builds up in sequence regardless of suit to king. The Two stack builds by counting by twos, overflowing from queen (12) to ace and on up to king (2-4-8-10-Q-A-3-5-7-9-J-K). Play to the Three stack counting by threes, and the last counting by fours. The top deck card may be played to a foundation stack, or discarded to one of the piles beneath the foundation. The top card in each discard pile may be played to a foundation stack. The game is won once all cards have been played to the foundation; all four stacks have a king. If no more possible moves exist, the game is lost.
